Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If single-color printing method is used for icon areas, then manufacturing process is simplified, but design freedom and design variety are limited
Solution Approach 1:
The patent applies parameter changes by utilizing the reflective properties of metal materials to create varied icon designs. By changing the physical parameter of using reflective metal patterns instead of printed colors, the system achieves diverse visual effects (reflective icons, transparent icons, mixed icons) without requiring multiple printing processes, thus maintaining manufacturing simplicity while greatly expanding design freedom
Solution Approach 2:
The patent employs composite materials by combining metal materials with transparent window materials to create icon areas with different optical properties. The metal patterns are integrated into the transparent window structure, creating composite regions that exhibit both transparency and reflectivity, enabling diverse icon designs through material composition rather than printing
2Adaptability or versatility
If separate printing process is performed for icons, then design flexibility is improved, but manufacturing process time increases
Solution Approach 1:
The patent merges the icon formation process with the sensing electrode pattern formation process. Both the sensing electrode patterns and the metal pattern parts for icons are formed simultaneously in the same manufacturing process, eliminating the need for separate printing steps. This integration maintains design flexibility through metal pattern variations while significantly reducing manufacturing time
Solution Approach 2:
The patent implements preliminary action by pre-forming the metal pattern parts during the sensing electrode pattern formation stage. The metal patterns are prepared in advance as part of the base structure, so that when icon designs are needed, they are already in place and can be selectively activated or configured without additional processing steps
3Productivity
If metal pattern parts are used for icons, then manufacturing efficiency is improved, but additional material costs may increase
Solution Approach 1:
The patent applies universality by using metal materials that serve multiple functions simultaneously. The same metal pattern parts function as both the icon display elements and the signal input units for touch sensing. This multi-functionality eliminates the need for separate materials for icons and sensors, reducing overall material usage and cost while maintaining high manufacturing efficiency
Solution Approach 2:
The metal pattern parts are self-serving by performing dual roles as both visual display elements (icons) and functional sensing elements (signal input units). This self-service capability means that a single material component fulfills multiple requirements, reducing the total quantity of materials needed and simplifying the manufacturing process
