Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If onboard electronic components are housed in a smaller size to meet volume constraints, then device compactness is improved, but heat management capability deteriorates
Solution Approach 1:
The patent extends the heat dissipation pathway from the electronic components through the temple structure to the ear, utilizing the third dimension (length along the temple) to provide adequate heat transfer surface area without increasing the volume of the housing containing the electronics. This allows compact electronics housing while maintaining effective heat management.
2Temperature
If heat dissipation surface area is increased to improve heat management, then temperature control is improved, but device weight increases
Solution Approach 1:
The temple structure serves multiple functions: it provides structural support for wearing the device, acts as a heat dissipation pathway, and contributes to the overall device aesthetics. By making the temple multi-functional, the patent avoids adding separate heat dissipation components that would increase weight, instead utilizing the existing temple structure for thermal management.
3Temperature
If heat dissipation surface area is increased to improve heat management, then temperature control is improved, but device complexity increases
Solution Approach 1:
The patent combines the heat dissipation function with the existing temple structure by thermally coupling the electronic components to the temple. This merging of functions eliminates the need for separate heat dissipation components and simplifies the overall device design while achieving effective thermal management.
4Ease of operation
If electronics are positioned closer to the user's body for wearability, then ease of operation is improved, but harmful thermal effects worsen
Solution Approach 1:
The patent extracts the heat from the vicinity of the user's face by providing a dedicated heat dissipation pathway through the temple structure that conducts heat away from the electronic components and away from the user's face to the ear, thereby eliminating thermal discomfort while maintaining wearability.

AI summary
Apparatuses, systems for electronic wearable devices such as smart glasses are described. The wearable device can comprise a frame, an elongate temple and an articulated joint. The frame can define one or more optical element holders configured to hold respective optical elements for viewing by a user in a viewing direction. The temple can be moveably connected to the frame for holding the frame in position when the device is worn by the user. The articulated joint can connect the temple and the frame to permit movement of the temple relative to the frame between a wearable position in which the temple is generally aligned with the viewing direction, and a collapsed position in which the temple extends generally transversely to the viewing direction. The articulated joint can include a base foot fixed to the frame and oriented transversely to the viewing direction.
