Innovation Solution
A connecting member with an elastically deformable securing member, made of plastic, that detachably connects to a receiving member within a housing, reducing production costs and improving safety by simplifying the installation process and eliminating the need for complex assembly techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal rivets are used for wall-hanging structures, then connection strength is improved, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent replaces expensive metal rivets with a disposable plastic connecting member that includes a breaking portion. This plastic connector is designed to be broken after use to facilitate disassembly, eliminating the need for expensive metal materials and complex riveting processes while maintaining adequate connection strength during the product's service life.
Solution Approach 2:
The patent replaces the mechanical riveting system with a breaking-based connection system. Instead of using metal rivets that require hot melt technology and complex assembly equipment, the invention uses a plastic connector with a breaking portion that can be easily broken to disconnect components, substituting a simple breaking action for a complex mechanical riveting process.
2Strength
If metal rivets are used for wall-hanging structures, then connection strength is improved, but assembly complexity and risk increase
Solution Approach 1:
The plastic connecting member with a breaking portion is designed as a disposable component that simplifies assembly. The breaking portion allows for easy disconnection by simple breaking actions, eliminating the need for complex riveting tools and procedures, thereby reducing assembly complexity and associated risks.
Solution Approach 2:
The patent replaces the complex mechanical riveting system with a simple breaking-based disconnection mechanism. The breaking portion is designed to be easily broken to disconnect the connecting member from the mounting hole, substituting a simple breaking action for a complex riveting and disassembly process.
3Ease of manufacture
If plastic material is used for connecting member, then manufacturing cost is reduced, but connection strength may decrease
Solution Approach 1:
The patent applies local quality by designing different portions of the plastic connecting member with different structural characteristics. The breaking portion is specifically designed with reduced thickness or structural weaknesses to facilitate easy breaking for disconnection, while other portions maintain sufficient thickness and structural integrity to provide adequate connection strength during the product's service life.
Solution Approach 2:
The patent uses composite material design by combining plastic material with a specifically engineered breaking portion structure. The breaking portion may incorporate design features such as reduced thickness, notches, or structural weaknesses that facilitate controlled breaking, while the overall plastic connector maintains sufficient strength through its geometry and material properties.
