Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal front frames are used for fixing the liquid crystal display panel, then the structural strength is improved, but the manufacturing cost increases and the weight increases
Solution Approach 1:
The patent changes the material parameter from metal to plastic, and changes the manufacturing process parameter from impact molding to vacuum molding. This allows the front frame to maintain sufficient structural strength while significantly reducing weight and manufacturing cost. The vacuum molding process enables the plastic sheet to conform precisely to the mold, achieving the required structural integrity without the need for heavy metal materials.
Solution Approach 2:
The patent replaces expensive metal front frames with cheaper plastic front frames formed by vacuum molding. This substitution reduces manufacturing cost while still providing adequate structural support for the liquid crystal display panel. The plastic material, though less durable than metal, provides sufficient service life for the application.
2Stability of the object's composition
If metal front frames are used for fixing the liquid crystal display panel, then the structural stability is improved, but the manufacturing cost and developing period increase
Solution Approach 1:
The patent changes the material parameter from metal to plastic and the manufacturing process from impact molding to vacuum molding. This reduces manufacturing cost and eliminates the need for separate mold design for each liquid crystal module, thereby shortening the developing period while maintaining structural stability through proper vacuum molding techniques.
Solution Approach 2:
The vacuum molding process serves multiple functions: it forms the front frame structure, provides the necessary structural stability, and can be adapted to different module designs without requiring separate molds. This universal manufacturing approach reduces both cost and development time compared to metal frame fabrication.
3Strength
If metal front frames made by impact molding are used, then the structural strength is improved, but the volume and weight increase which is not beneficial for light and thin design
Solution Approach 1:
The patent changes the material parameter from metal to plastic and uses vacuum molding instead of impact molding. This allows the front frame to achieve the required structural strength with reduced volume and weight. The vacuum molding process enables the plastic sheet to conform precisely to the desired shape, eliminating the excess material volume associated with metal frame fabrication.
Solution Approach 2:
The patent uses a plastic sheet as a flexible material that can be molded into the required frame shape. This thin film approach allows the front frame to maintain structural integrity while having minimal volume and weight, enabling light and thin design of the liquid crystal module.
