Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a touchscreen display device is made thin and lightweight, then portability and aesthetic appearance are improved, but structural strength and durability deteriorate
Solution Approach 1:
The patent employs a composite structure combining multiple materials with different properties: a flexible polymer layer (ELASTOMER) for cushioning, a metal layer (ALUMINUM) for structural strength, and a glass layer for display protection. This composite approach allows the device to maintain both thinness and structural integrity by leveraging the complementary strengths of each material.
Solution Approach 2:
The patent implements a multi-layer nested structure where the flexible polymer layer, metal layer, and glass layer are stacked and integrated together. Each layer is nested within the device housing, with the flexible layer positioned between the display and the housing, the metal layer providing internal reinforcement, and the glass layer forming the outer display surface. This nesting arrangement maximizes space utilization while maintaining structural strength.
2Device complexity
If the device structure is simplified to reduce complexity, then manufacturing cost is reduced, but impact resistance and durability worsen
Solution Approach 1:
The flexible polymer layer serves multiple functions simultaneously: it acts as a cushioning element to absorb impact, provides structural support, and serves as part of the display assembly mounting structure. This multi-functionality reduces the need for separate protective components, simplifying the overall device structure while maintaining impact resistance.
Solution Approach 2:
The patent merges the protective cushioning function with the structural support function by integrating the flexible polymer layer into both the display assembly and the housing structure. The metal layer is also integrated to provide both structural reinforcement and attachment points for internal components. This merging of functions reduces component count and structural complexity while maintaining durability.
