Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light adjustment devices require a large number of external coupling wires, which complicates the structure and increases the risk of electrical coupling failures due to the long length of the conductive members.
Innovation Solution
A light adjustment device and manufacturing method that reduces the number of external coupling wires by using a conductive member with a body portion extending in the stacking direction and an insertion portion protruding from it, which is inserted between substrates and electrically coupled to the terminals, with a sealing member preventing excessive insertion and potential breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of external coupling wires are used to connect terminals of substrates in each light adjustment panel, then each panel can be electrically connected, but the number of wires increases, complicating the structure and increasing the risk of electrical coupling failures
Solution Approach 1:
The patent merges multiple separate external coupling wires into a single integrated conductive member that extends through the stacking direction of multiple light adjustment panels. This conductive member simultaneously connects corresponding terminals across multiple panels, reducing the total number of wires while maintaining electrical connectivity, thereby simplifying the structure and improving reliability.
Solution Approach 2:
The patent transitions from using multiple wires in the planar direction (horizontal connections) to using a single conductive member extending in the stacking direction (vertical dimension). This dimensional change allows one wire to replace multiple wires by utilizing the third dimension (depth/stacking direction) to establish electrical connections across multiple panels simultaneously.
2Ease of operation
If long external coupling wires are used to connect terminals, then electrical connections can be established across multiple panels, but the long wire length increases the risk of electrical coupling failures
Solution Approach 1:
The patent segments the long external coupling wire into multiple short segments, where each segment connects adjacent terminals within or between neighboring panels. By dividing the long connection path into shorter segments, the electrical coupling failure risk is reduced while maintaining the ability to establish electrical connections across the entire stack of panels.
Solution Approach 2:
The patent eliminates the need for long planar wires by utilizing the stacking direction (vertical dimension) to create short vertical connections. Instead of routing wires horizontally across multiple panels (long path), the conductive member extends vertically through the stack, creating short connection segments that reduce failure risk.
3Reliability
If the insertion portion of the conductive member is allowed to extend freely between substrates, then electrical coupling can be achieved, but the conductive member may be excessively inserted and break
Solution Approach 1:
The patent incorporates a sealing member between substrates that performs the preliminary action of limiting the insertion depth of the conductive member's insertion portion. This sealing member acts as a mechanical stop that prevents excessive insertion before the conductive member can be broken, thereby protecting the structural integrity while maintaining electrical coupling functionality.
Solution Approach 2:
The sealing member provides beforehand cushioning by being positioned between the substrates to prevent the insertion portion from being pushed too deep. This cushioning effect absorbs the excess insertion force and stops the insertion portion at a safe depth, preventing breakage while still allowing sufficient insertion for electrical coupling.
