Matthias et al. discloses an automotive radar provided with a housing and a cover, where multiple radar sensors are disposed at a preset angle to one another.
Shigemoto discloses a connector detachably mounted in a connector port with an O-ring.
Phillip et al. discloses a sensor assembly comprising a housing base made of an aluminum alloy
Shi et al. as modified above discloses the radar of claim 6. However, Shi et al. as modified above fails to explicitly disclose a heat dissipation assembly comprising heat dissipation pads and heat dissipation pieces. This feature is disclosed by Matthias et al. where the support 14 is provided to dissipate heat from the printed circuit board 16, the support 14 comprises facets 74 and 76 that support the radar antennas 144 and 146, and fins 110, 112, 114 that dissipate heat away from the fins (Matthias et al. p. 4-5; Fig. 1). The combination of Shi et al., Matthias et al., Shigemoto, and Phillip et al. would be obvious with a reasonable expectation of success to dissipate heat from the antenna assemblies, protect the radar antennas and reduce detection errors (Matthias et al. p. 2, 8), to simplify manufacturing by press-fitting (Shigemoto Col. 4, lines 45-50) and prevent water immersion into the case from the connector port (Shigemoto Col. 3, lines 42-43), to improve EMC shielding and dissipate heat (Phillip et al. ¶ [0005]).
Claim(s) 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shi et al. (CN 112213726 A, cited by applicant in IDS dated 24 April 2024) in view of Matthias et al. (FR 3063160 A1, cited by applicant in IDS dated 11 October 2024), Shigemoto (US 7,776,046 B2) and Phillip et al. (US 2015/0331087 A1) as applied to claim 6 above, and further in view of Zhang et al. (CN 110082767 A, cited by applicant in IDS dated 24 April 2024).
Regarding claim 10 (Original), Shi et al. discloses:
[Note: what is not explicitly taught by Shi et al. has been struck-through]
The radar according to claim 6
Zhang et al. discloses:
the radar further comprises a sealing ring (Zhang et al. sealing ring 282, Fig. 4), the base (Zhang et al. base 26, Fig. 4) is provided with a sealing groove (Zhang et al. sealing ring groove 262, Fig. 4), the sealing ring is provided on the sealing groove (Zhang et al. “a second sealing ring 282 is provided on one side of the sealing ring groove 262” - ¶ [0053]), and when the upper cover (Zhang et al. intermediate shelf 25, Fig. 4) covers the base, an inner wall (Zhang et al. positioning protruding ring 255, Fig. 4) of the upper cover abuts against the sealing ring (Zhang et al. “The positioning protruding ring 255 is installed in the sealing ring groove 262” - ¶ [0053]).
It would have been obvious to someone with ordinary skill in the art prior to the effective filing date of the claimed invention to incorporate the features as disclosed by Zhang et al. into the invention of Shi et al. as modified above to yield the invention of claim 10. Shi et al., Matthias et al., Shigemoto and Phillip et al. are considered analogous arts to the claimed invention as they disclose the features listed below.
Shi et al. discloses a blind spot warning radar with a first detection assembly and a second detection assembly configured to provide a superimposed viewing angle greater than 180 degrees.
Matthias et al. discloses an automotive radar provided with a housing and a cover, where multiple radar sensors are disposed at a preset angle to one another.
Shigemoto discloses a connector detachably mounted in a connector port with an O-ring.
Phillip et al. discloses a sensor assembly comprising a housing base made of an aluminum alloy
Zhang et al. discloses a radar assembly comprising sealing rings and sealing ring grooves between base and top cover.
Shi et al. as modified above discloses the radar of claim 6. However, Shi et al. as modified above fails to explicitly disclose the radar further comprises a sealing ring, the base is provided with a sealing groove, the sealing ring is provided on the sealing groove, and when the upper cover covers the base, an inner wall of the upper cover abuts against the sealing ring. This feature is disclosed by Zhang et al. where the base 26 comprises a sealing ring groove 262, a sealing ring 282 is provided in the sealing ring groove 262 and the positioning convex ring 255 of the intermediate shelf 25 abuts the sealing ring 282 (Zhang et al. Fig. 4). The combination of Shi et al., Matthias et al., Shigemoto, Phillip et al., and Zhang et al. would be obvious with a reasonable expectation of success to dissipate heat from the antenna assemblies, protect the radar antennas and reduce detection errors (Matthias et al. p. 2, 8), to simplify manufacturing by press-fitting (Shigemoto Col. 4, lines 45-50) and prevent water immersion into the case from the connector port (Shigemoto Col. 3, lines 42-43), to improve EMC shielding and dissipate heat (Phillip et al. ¶ [0005]) and to provide a sealed installation (Zhang et al. ¶ [0025])
