Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If upper and lower metallic shells are used to sandwich the display panel, then the display structure is strong and protective, but the thickness and weight of the device are increased
Solution Approach 1:
The patent replaces rigid metallic shells with a flexible bendable cover comprising a cover body and adhesive layer. The cover body is made of flexible material that can be bent and adhered to the display module, providing protection while significantly reducing weight and thickness compared to traditional metallic shell structures.
Solution Approach 2:
The patent uses composite material structure for the bendable cover, combining a flexible cover body material with an adhesive layer. This composite structure provides both mechanical protection and strong adhesion to the display module, replacing the need for heavy metallic shells while maintaining protective strength.
2Strength
If upper and lower metallic shells are used to sandwich the display panel, then the display structure is strong and protective, but the thickness of the device is increased
Solution Approach 1:
The flexible bendable cover can be made as a thin film structure that conforms to the display module surface, providing protection without adding significant thickness. The cover body is designed to be thin yet flexible, allowing it to adhere closely to the display module without creating bulk.
Solution Approach 2:
The protective structure is segmented into the cover body and adhesive layer as separate functional components. The adhesive layer provides the bonding function while the cover body provides protection, allowing each component to be optimized for its specific function with minimal thickness.
3Reliability
If metallic shells are used for the display structure, then the display is protected, but material cost and manufacturing cost are increased
Solution Approach 1:
The patent replaces expensive metallic shells with a more cost-effective flexible cover material. The cover body can be made from inexpensive flexible materials that provide adequate protection for the display module, significantly reducing material cost while maintaining protective function.
Solution Approach 2:
The composite structure of flexible cover body and adhesive layer uses lower-cost materials compared to metallic shells. The adhesive layer can be applied through simple coating processes, reducing manufacturing complexity and cost while achieving reliable adhesion and protection.
4Stability of the object's composition
If metallic shells are used with manual assembly, then the display structure is stable, but assembly time and labor cost are increased
Solution Approach 1:
The adhesive layer is pre-applied to the cover body or display module before assembly, eliminating the need for complex fastening operations during assembly. This preliminary bonding action allows for rapid assembly while ensuring stable attachment of the cover to the display module.
Solution Approach 2:
The patent replaces mechanical assembly methods (screws, clips, or other fasteners) with adhesive bonding. This substitution eliminates complex mechanical fastening operations, reducing assembly time and labor requirements while providing stable and uniform attachment across the entire cover surface.
5Device complexity
If metallic shells are used with gaps between shell and panel, then the assembly is simple, but dust and water vapor can enter the device
Solution Approach 1:
The patent extracts and eliminates the gap problem inherent in metallic shell structures by using a flexible cover that can conform perfectly to the display module surface. The adhesive layer ensures complete contact between the cover and module, removing the gaps that would allow dust and water vapor ingress.
Solution Approach 2:
The flexible cover body can be bent and molded to match the exact contours of the display module, ensuring complete surface contact without gaps. This flexibility allows the cover to adapt to the module shape, eliminating the air gaps and contamination pathways present in rigid metallic shell assemblies.
