Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display apparatuses face challenges in assemblability due to the need for screws, which increase manufacturing costs and time, and hinder the implementation of a slim design due to thickness limitations.
Innovation Solution
A display apparatus with a snap button coupling mechanism, featuring a moving part and a fixing part, allows for removably coupled components, eliminating the need for screws and enabling easier assembly and a slimmer design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to couple components, then the components can be securely fastened, but the manufacturing cost increases and assembly time increases
Solution Approach 1:
The patent removes screws and coupling tools from the assembly process by implementing a snap-button coupling mechanism. The coupling members are integrated directly into the chassis and cover structures, allowing components to be fastened through simple insertion and snapping actions without requiring external fastening tools or separate screw components.
Solution Approach 2:
The coupling members are designed to be self-fastening through elastic deformation. When the cover is inserted onto the chassis, the elastic coupling members automatically deform and snap into place, securing the components together without requiring external tools or additional assembly steps.
2Strength
If screws are used to couple components, then the components can be securely fastened, but the manufacturing cost increases
Solution Approach 1:
The patent combines the coupling function with the existing chassis and cover structures. The coupling members are integrated into these components rather than being separate parts, eliminating the need for additional screws and reducing the total number of components. This integration simplifies the manufacturing process and reduces material costs.
Solution Approach 2:
The coupling members are designed as simple, inexpensive plastic components that can be easily manufactured and replaced if needed. Their simple geometry and use of common materials make them much cheaper than metal screws, while still providing sufficient coupling strength for the application.
3Strength
If screw threads are used for assembly, then components can be coupled, but the display apparatus thickness must exceed the screw thread length
Solution Approach 1:
The patent removes the screw threads entirely from the coupling mechanism. Instead of using threaded fasteners that require significant insertion depth, the design employs snap-button coupling members that achieve secure fastening through elastic deformation and geometric interlocking, requiring minimal thickness.
Solution Approach 2:
The patent changes the coupling mechanism from mechanical threading to elastic snapping. This parameter change allows the coupling members to achieve secure fastening with much smaller dimensions, enabling the display apparatus to achieve a thinner profile while maintaining coupling strength.
