Claim(s) 1 - 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over as applied to Shah (US 20190177123 A1), in further view of Gillingham (US 5931264 A); in further view of Ong (NPL Ong, E. H. (2019). Design and development of 3D visual mapping system for elevator shaft inspection. Master's thesis, Nanyang Technological University, Singapore).
Regarding claim 1 Shah teaches An elevator inspection system, comprising: a sensor implement; a robotic platform, which is portable, supporting the sensor implement, the robotic platform configured for inspecting and performing maintenance to one or more components previously installed in a hoistway; a controller operationally connected to the robotic platform and the sensor implement, wherein the controller is configured to: (Shah [0013] reads “Aspects of the present invention relate to an elevator inspection and maintenance system including a mechatronic body movable via remote or automatic operation, and an inspection and maintenance head installed on the mechatronic body. The inspection and maintenance head is fitted with a sensor or a manipulation tool to perform an inspection or a maintenance operation on at least one component of an elevator system, remotely or automatically.”);
and thereafter utilize the hoistway model data for as a reference point for maintaining the one or more components previously installed in a hoistway, by being configured to: control movement of the robotic platform within the hoistway; (Shah [0013] reads “Aspects of the present invention relate to an elevator inspection and maintenance system including a mechatronic body movable via remote or automatic operation, and an inspection and maintenance head installed on the mechatronic body. The inspection and maintenance head is fitted with a sensor or a manipulation tool to perform an inspection or a maintenance operation on at least one component of an elevator system, remotely or automatically.”);
and engage the one or more components, with the robotic platform to execute corrective measures, upon identifying, from the sensor data compared with the hoistway model data, when the one or mere components installed in the hoistway is outside of predetermined tolerances. (Shah [0034 – 0035] reads “The manipulation tool 164 can be any tool known in the art, configured to manipulate or perform a maintenance operation on any hoist way equipment 106. There may be more than one manipulation tools in inspection and maintenance head 160. Some examples of such manipulation tools include screw driver, a gripper, wire cutter, adhesive gun, soldering iron, welding tool, etc. In some embodiments, the manipulation tool 164 includes a movable claw that is used by the system 150 for gripping various types of equipment 106 within the hoist way 102 to closely inspect equipment 106 using the sensors in the sensor hub 162.”);
Shah does not teach develop hoistway model data from sensor data of the hoistway, from sensed locations and shape boundaries of the hoistway shaft and doorway openings formed in the hoistway shaft, by moving the sensor implement within the hoistway via the robotic platform, wherein the hoistway model data is a three-dimensional hoistway model of the hoistway, including sill to sill distances, guide rail to guide rail distances, sill to guide rail distances, and tilt and twist of the hoistway; and inspect the one or more components previously installed in the hoistway to determine, from sensor data compared with hoistway model data, that an operational parameter or an alignment of the one or more components previously installed in the hoistway is outside predetermined positioning and operating tolerances;
Gillingham in analogous art, teaches and inspect the one or more components previously installed in the hoistway to determine, from sensor data compared with hoistway model data, that an operational parameter or an alignment of the one or more components previously installed in the hoistway is outside predetermined positioning and operating tolerances; (Gillingham column 3 lines 8 - 7 reads “According to another embodiment of the present invention, the device is equipped with optical sensors for detecting the occurrence of rail support brackets and splice joints or fishplates disposed between adjacent rail segments. The occurrence of such brackets and joints is recorded, along with their positions along the length of the guide rail. These data may then be used to identify not only at which point the rail profile has most deviated from its intended linear path, but also which rail brackets or joints may be adjusted to correct the deviations” and column 4 lines 9-24 reads “As noted hereinabove, nonlinearities occur in the guide rails 20, 22 during installation, as the rails are first installed; during operation, as the elevator moves within the hoistway 12 during normal operation thereby stressing and thereby possibly moving the rails; and due to building settling, thermal expansion, etc., over an extended period of time. For a modem, high-rise, high-velocity elevator system, it is necessary to maintain any misalignment of the elevator guide rails within a close tolerance. It is therefore necessary to precisely measure the profile of the elevator guide rails 20, 22 over their entire length.”);
It would have been obvious to one with ordinary skill in the art, before the effective filing date of the claimed invention to have modified the teachings of Shah with that of Gillingham to include a method of measuring tolerances and modifying existing items in the elevator shaft. This would allow for quicker and safe inspection and maintenance of components in the elevator shaft. (Gillingham column 2 lines 4 – 7 reads “What is needed is a method and apparatus for reducing the time required to survey an elevator guide rail”);
Shah/Gillingham does not teach develop hoistway model data from sensor data of the hoistway, from sensed locations and shape boundaries of the hoistway shaft and doorway openings formed in the hoistway shaft, by moving the sensor implement within the hoistway via the robotic platform, wherein the hoistway model data is a three-dimensional hoistway model of the hoistway, including sill to sill distances, guide rail to guide rail distances, sill to guide rail distances, and tilt and twist of the hoistway;

This also applies to elevator shaft” and page 102 reads “Cloud/Mesh Dist tool is used to calculate the distance between the point clouds of the surface to the best fitted flat plane.“);
It would have been obvious to one with ordinary skill in the art, before the effective filing date of the claimed invention to have modified the teachings of Shah/Gillingham with that of Ong to include more advanced sensors and computational software. This would all the system take more accurate measurements of the elevation shaft, thereby providing an improved inspection. (Ong abstract reads “In this thesis, the design and development of an 3D visual elevator shaft inspection system concept is proposed, which has potential to improve the yield and speeds up the elevator shaft inspection process”);

(Gillingham [0009] reads “For other misalignments, workers may attempt to loosen the mounting bracket, move the rail accordingly, and resecure the rail in the correct position. Upon completion of the realignment, it is then necessary to again survey the rails to determine if the realignment has been successful”);

For other misalignments, workers may attempt to loosen the mounting bracket, move the rail accordingly, and resecure the rail in the correct position.”);
Regarding claim 6 Shah/Gillingham/Ong teaches The system of claim 1, wherein the controller is configured to engage the guide rail by loosening rail securing bolts, aligning the guide rail, and tightening rail securing bolts.

The relative location data, collected for each point along the rail 32, may then easily be used as a basis to determine the exact local deflection or profile of the rail 32 along its length” and column 4 lines 9-24 reads “As noted hereinabove, nonlinearities occur in the guide rails 20, 22 during installation, as the rails are first installed; during operation, as the elevator moves within the hoistway 12 during normal operation thereby stressing and thereby possibly moving the rails; and due to building settling, thermal expansion, etc., over an extended period of time. For a modem, high-rise, high-velocity elevator system, it is necessary to maintain any misalignment of the elevator guide rails within a close tolerance.
