Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If markers are printed on paper, then they are easy to produce, but the boundary line is unclear and accuracy is insufficient
Solution Approach 1:
The marker uses a composite structure consisting of a base material layer and a color layer with different refractive indices. This composite material approach creates an optical contrast that defines clear boundary lines without requiring complex machining, thus maintaining ease of manufacture while achieving high precision.
Solution Approach 2:
The invention utilizes optical contrast through color layer design where the color layer has a different refractive index than the base material. This creates visible boundary lines through optical effects rather than physical boundaries, solving the precision problem while keeping the manufacturing process simple.
2Ease of manufacture
If markers are printed on paper, then they are easy to produce, but size changes due to expansion and contraction
Solution Approach 1:
The marker employs a composite structure with a base material layer and a color layer having different refractive indices. This composite design provides dimensional stability because the rigid base material resists expansion and contraction, while the color layer maintains its optical properties, ensuring consistent marker dimensions under varying environmental conditions.
3Manufacturing precision
If holes are cut and filled with resin to form markers, then accuracy is improved, but manufacturing time and labor increase
Solution Approach 1:
The invention replaces complex mechanical machining processes (cutting holes and filling with resin) with a simpler lamination process. The marker is formed by laminating a color layer onto a base material layer, which achieves high accuracy through optical contrast without requiring time-consuming mechanical operations, thus improving manufacturing efficiency.
Solution Approach 2:
The base material layer is prepared in advance with the marker pattern formed through simple lamination of the color layer. This preliminary preparation of the base material allows for rapid production while maintaining high accuracy, eliminating the need for time-consuming post-processing steps.
4Ease of manufacture
If simple markers are used, then manufacturing is easy, but boundary lines are unclear under strong illumination
Solution Approach 1:
The invention uses optical contrast created by the different refractive indices between the base material layer and the color layer. This optical contrast ensures that boundary lines remain clearly visible under various lighting conditions including strong illumination, while the manufacturing process remains simple. The color layer acts as an optical element that enhances visibility without adding manufacturing complexity.
