Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple splicing units are combined to create large-sized electronic devices, then the device size and functionality are improved, but optical consistency and static electricity control at joints deteriorate
Solution Approach 1:
The patent applies local quality by implementing a light shielding layer specifically at the joint regions between splicing units, where optical inconsistency occurs. The light shielding layer has different properties (light blocking function) compared to the main display areas, addressing the local optical problem at joints while maintaining overall device functionality. This localized treatment resolves the contradiction by improving joint optical consistency without compromising the large device size.
2Area of stationary object
If multiple splicing units are combined to create large-sized electronic devices, then the device size and functionality are improved, but static electricity accumulation at joints worsens
Solution Approach 1:
The patent introduces an intermediary component - the light shielding layer with conductive properties - at the joint regions between splicing units. This intermediary layer serves dual functions: it shields light to improve optical consistency and simultaneously provides a conductive path to dissipate static electricity accumulation. By placing this intermediary element at the critical joint locations, the patent resolves the static electricity problem while maintaining the benefits of large device size achieved through splicing.
3Reliability
If a light shielding layer is added at joint regions, then optical consistency is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the light shielding layer to perform multiple functions simultaneously: light shielding to improve optical consistency and static electricity dissipation through its conductive properties. By making this single component multi-functional, the patent improves joint optical consistency without proportionally increasing device complexity, as one layer addresses both optical and electrical issues rather than requiring separate components for each function.
