Watch Display Connecting Member Positioning for Compact Solar Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display device configurations for watches, which include a liquid crystal display panel and a solar panel, face challenges in arranging connecting members due to the panel's presence, requiring larger solar panels and limiting the arrangement of electronic components.
Innovation Solution
A display device design that positions the connecting members near the outer peripheral portion of the liquid crystal panel, avoiding contact with it, allowing for a more compact and efficient arrangement of the solar panel and electronic components, utilizing a coil spring configuration for connection between the solar panel and circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid crystal display panel is arranged between the solar panel and circuit board, then the display functionality is achieved, but the arrangement space for connecting members is restricted
Solution Approach 1:
The connecting member is positioned in the planar dimension near the outer peripheral portion of the liquid crystal display panel, rather than being constrained to the vertical stacking dimension. This spatial reconfiguration in another dimension resolves the conflict between display functionality and connecting member arrangement.
2Area of moving object
If the liquid crystal display panel is made larger, then the display area is increased, but the solar panel needs to be increased in size to accommodate the connecting member arrangement
Solution Approach 1:
The connecting member is extracted from the central arrangement space and repositioned to the outer peripheral portion of the liquid crystal display panel. This extraction frees up the central area, allowing the solar panel to maintain a smaller size while still accommodating all necessary connections.
3Illumination intensity
If the connecting member is arranged to avoid the liquid crystal display panel, then the display visibility is maintained, but the connecting member arrangement becomes more complex
Solution Approach 1:
The connecting member is positioned locally at the outer peripheral portion of the liquid crystal display panel, a specific location that naturally avoids interference with the display area. This localized placement maintains display visibility while simplifying the overall arrangement compared to more complex routing paths.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables effective space utilization, miniaturization of the device, and cost reduction by allowing the use of coil springs instead of flexible boards, while maintaining the visibility and functionality of the watch's display.
Implementation Method 1
a connecting member arranged in a position which is in a vicinity of an outer peripheral portion of the ODF liquid crystal panel and in which the connecting member is not in contact with the ODF liquid crystal panel, the connecting member being configured to connect the solar panel and the circuit board
