Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid support components are used to provide structural support, then supporting capability is improved, but rebound force is reduced and warping occurs during rolling processes
Solution Approach 1:
The patent employs a composite structure consisting of a rigid support component embedded in an elastic component. The rigid support component (made of materials like aluminum alloy or stainless steel) provides structural strength and support capability, while the elastic component (made of materials like silicone rubber or thermoplastic elastomer) provides rebound force and flexibility. This composite configuration allows the display module to maintain both supporting capability and rebound performance, resolving the contradiction between strength and reliability.
2Stability of the object's composition
If rigid support components are used to maintain display panel stability, then stability is improved, but warping occurs during rolling processes reducing lifespan
Solution Approach 1:
The patent uses an elastic component in the form of a flexible layer or film that encapsulates the rigid support component. This elastic component allows the display module to bend and roll without causing warping, while the embedded rigid support component maintains panel stability during use. The flexible nature of the elastic component enables repeated rolling and unrolling cycles, significantly extending the lifespan of the display module.
3Device complexity
If the rigid support component structure is simplified, then device complexity is reduced, but supporting and restoring performances are insufficient
Solution Approach 1:
The rigid support component is segmented into multiple layers with different elastic moduli. The first support layer has a lower elastic modulus for flexibility, while the second support layer has a higher elastic modulus for structural strength. This segmentation allows each layer to perform its specific function optimally, achieving both supporting and restoring performances without excessive structural complexity.
Solution Approach 2:
Different regions of the rigid support component have different elastic moduli tailored to their specific functions. The first support layer uses materials with lower elastic modulus where flexibility is needed, while the second support layer uses materials with higher elastic modulus where structural strength is required. This local quality optimization enables the structure to achieve superior supporting and restoring performances with controlled complexity.
