Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rigid nature of motherboards and batteries limits the flexibility of flexible screens, which can only be bent at the edges, and the thin and light features of flexible screens are not fully realized due to these constraints.
Innovation Solution
A power supply module with a flexible substrate and arrayed battery cells connected in series and parallel by flexible connectors, allowing the battery cells to be distributed across the substrate for enhanced flexibility and power supply to a flexible display screen, along with wireless charging capabilities and a flexible packaging film for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid motherboards and batteries are used, then structural stability is improved, but flexibility of the display device deteriorates
Solution Approach 1:
The battery is divided into multiple battery cells arranged in an array on the flexible substrate. Each battery cell is independently connected through flexible connectors, allowing the battery structure to be segmented and flexible while maintaining stability through the organized array configuration
Solution Approach 2:
The rigid battery structure is replaced with a flexible substrate containing arrayed battery cells. The flexible substrate and flexible connectors enable the battery to bend and flex, eliminating the rigid structure while maintaining structural integrity through the distributed array configuration
2Reliability
If rigid batteries are used, then power supply stability is improved, but weight of the display device increases
Solution Approach 1:
The battery is segmented into multiple smaller battery cells distributed in an array on the flexible substrate. This segmentation reduces the weight concentration and allows for a lighter overall structure while maintaining power supply stability through the collective capacity of multiple cells connected in series and parallel
3Quantity of substance
If traditional battery structures are used, then power capacity is improved, but flexibility of the display device deteriorates
Solution Approach 1:
The battery capacity is distributed across multiple battery cells arranged in an array, with series connections increasing voltage and parallel connections increasing capacity. This segmented approach maintains high power capacity while enabling flexibility through the distributed configuration on the flexible substrate
Solution Approach 2:
The battery cells are arranged in a two-dimensional array on the flexible substrate rather than a single block structure. This spatial distribution in multiple dimensions allows the battery to flex and bend while maintaining electrical connections through the flexible connectors and electrode patterns
