Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electrical components are arranged in a small space to achieve miniaturization, then device size is reduced, but heat dissipation becomes insufficient
Solution Approach 1:
The patent introduces a transparent conductive line extending from the lens frame to the front surface of the lens, creating a new spatial dimension for heat dissipation. This allows heat to be conducted along the conductive line to the outer surface of the device, effectively utilizing the three-dimensional space available in the wearable device structure to resolve the heat dissipation problem caused by miniaturization.
2Temperature
If heat diffuser is added to improve heat dissipation, then heat management improves, but device space is insufficient
Solution Approach 1:
The transparent conductive line serves multiple functions: it acts as a heat dissipation pathway while also maintaining the optical transparency of the lens assembly. By making the conductive element transparent, the patent eliminates the need for separate heat diffuser components that would occupy space, as the conductive line integrates heat management functionality into the existing lens structure without compromising optical performance.
Solution Approach 2:
The transparent conductive line functions as a thin-film heat conduction path that can be integrated into the lens assembly. This thin-film approach allows heat dissipation without adding significant volume, as the conductive line has minimal thickness while still providing effective thermal conduction from the electrical components to the external environment.
3Temperature
If transparent conductive line is used for heat dissipation, then heat is dissipated effectively, but manufacturing complexity increases
Solution Approach 1:
The patent combines the heat dissipation function with the existing transparent conductive lines used for other purposes in the display system. By merging multiple functions into the same transparent conductive structure, the patent avoids the need for separate manufacturing processes for heat management components, thereby reducing overall manufacturing complexity despite the innovative heat dissipation approach.
