Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If column-by-column splicing of light boards is used, then the light box can be assembled, but tolerance accumulation affects viewing quality
Solution Approach 1:
The patent introduces an arc-shaped bracket as an intermediary component between the light boards. The bracket provides a precise arc-shaped positioning structure that serves as a reference for splicing multiple light boards, eliminating tolerance accumulation by providing a consistent geometric reference throughout the assembly process.
Solution Approach 2:
The patent replaces traditional mechanical positioning methods with magnetic positioning posts. These posts use magnetic attraction forces to hold light boards in precise positions on the arc-shaped bracket, providing more stable and accurate positioning compared to purely mechanical connection methods.
2Adaptability or versatility
If different specifications of light boards are used for various shapes, then the light box can accommodate shape variety, but manufacturing cost and time increase
Solution Approach 1:
The patent designs light boards with universal dimensions and standardized splicing structures that can be used across different light box shapes. The arc-shaped bracket and magnetic positioning posts provide a flexible framework that allows the same light board specifications to be adapted to various configurations, eliminating the need for custom-manufactured boards for each shape.
Solution Approach 2:
The patent employs adjustable magnetic positioning posts that can be repositioned along the arc-shaped bracket. This dynamic positioning capability allows the same set of light boards to be configured for different shapes by adjusting the position of the magnetic posts, providing versatility without requiring different board specifications.
3Adaptability or versatility
If traditional positioning mechanisms are used, then material ductility and thermal variation can be accommodated, but precise positioning cannot be achieved
Solution Approach 1:
The patent replaces traditional mechanical positioning mechanisms with magnetic positioning posts. The magnetic attraction provides continuous, precise positioning force that is not affected by material ductility or thermal expansion, maintaining positioning precision while accommodating material variations through the flexible magnetic field.
