Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device housings lack dynamic visual effects, as their exterior decorative features are static and fail to meet consumer demands for a 'cool' appearance.
Innovation Solution
A housing design incorporating a flexible first textured membrane and a flexible second textured membrane, stacked with different texture patterns, which deform under external forces to change refraction angles and create dynamic interference effects, allowing for dynamic texture changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static texture patterns are used on the housing, then the manufacturing process is simple, but the visual effect is static and cannot dynamically change
Solution Approach 1:
The patent applies the dynamics principle by making the second textured membrane flexible instead of rigid, allowing it to deform under external forces such as finger pressing or sliding. This deformation dynamically changes the refraction angle of light rays passing through the membrane, thereby dynamically altering the interference effect between the first and second texture layers. The housing transitions from a static appearance to a dynamic one that responds to user interaction, resolving the contradiction between visual adaptability and structural complexity.
Solution Approach 2:
The patent employs parameter changes by modifying the physical state of the second textured membrane from rigid to flexible, enabling it to change its thickness and refraction angle parameters in response to external forces. When a user presses or slides on the housing, the membrane's thickness at the pressed position changes, which alters the refraction angle and consequently changes the interference pattern. This dynamic parameter adjustment allows the housing to display different visual effects without changing its basic structure, achieving adaptability while controlling complexity.
2Adaptability or versatility
If flexible textured membranes are used to achieve dynamic visual effects, then the appearance can change with user gestures, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the housing into multiple functional layers: a first textured membrane with a first texture layer and first bearing layer, and a second textured membrane with a second texture layer and second bearing layer. Each layer has a specific function - the bearing layers provide structural support and facilitate deformation, while the texture layers create the visual effects. This segmentation allows each layer to be manufactured and optimized independently, reducing the overall manufacturing precision requirements compared to a single integrated structure.
Solution Approach 2:
The patent uses composite materials by combining different functional layers - flexible bearing layers and textured film layers - to create the textured membranes. The bearing layers are made from flexible materials that can deform under external forces, while the texture layers are patterned films that create optical effects. This composite structure allows each material to be selected and manufactured according to its specific requirements, then assembled together, thereby reducing the overall manufacturing precision burden while achieving dynamic texture changes.
