Wearable Display Dual Circuit Boards Signal Line Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices, such as AR glasses, face challenges with increased volume and weight due to the large number of signal lines connecting electronic components, limiting design flexibility and comfort when worn on the head.
Innovation Solution
A dual operating system is implemented, with independent processors and circuit boards for each eye, using a board-to-board connector for synchronization, and a connection member in the lens frame to reduce the number of signal lines and distribute weight more evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If many connectors are provided to electrically connect multiple electronic components, then signal connection completeness is improved, but device volume increases
Solution Approach 1:
The patent divides the electronic components into two separate groups: a first group including a first display member and first electronic component disposed on a first circuit board, and a second group including a second display member and second electronic component disposed on a second circuit board. This segmentation reduces the need for numerous connectors by creating modular, independently functional units that can be connected through fewer interface points.
2Device complexity
If many signal lines are concentrated on one side, then connection simplicity is improved, but calorific value increases
Solution Approach 1:
The patent segments the signal lines and electronic components into two separate circuit boards, distributing the signal lines and heat-generating components across different physical locations. This prevents concentration of signal lines on one side and distributes thermal load, reducing localized calorific value while maintaining connection simplicity through standardized interface connectors.
3Volume of moving object
If electronic components are integrated in a compact space, then device miniaturization is improved, but design flexibility is limited
Solution Approach 1:
The patent employs segmentation by creating modular first and second circuit boards that can be independently designed, configured, and optimized. This modularity enables compact integration while maintaining design flexibility, as each module can be separately adjusted or replaced without affecting the entire system. The segmented architecture allows for adaptable configuration of display members and electronic components within a reduced overall device volume.
