Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screwing fashion is used to fix antenna module, then connection strength is improved, but operation complexity increases and assembly/disassembly time increases
Solution Approach 1:
The patent replaces the traditional screwing mechanical system with a snap-fit mechanism consisting of a buckle, elastic member, and fastening recess. This substitution eliminates the need for screwdrivers and wrenches, transforming a complex tool-based mechanical operation into a simple tool-free snap-in/snap-out action while maintaining secure connection strength.
Solution Approach 2:
The elastic member automatically engages the buckle with the fastening recess through elastic force, creating a self-locking mechanism that secures the antenna module without requiring additional fastening operations. The mechanism serves itself by using the elastic deformation of the member to both install and lock the connection.
2Reliability
If screwing fashion is used to fix antenna module, then connection reliability is improved, but assembly/disassembly speed decreases
Solution Approach 1:
The elastic member is pre-loaded and positioned within the buckle structure before assembly. When the antenna module is inserted, the elastic member is already ready to engage the fastening recess, eliminating the need for sequential fastening operations. This preliminary preparation enables rapid one-action assembly while ensuring reliable engagement.
Solution Approach 2:
The multi-step screwing process is replaced with a single-snap snap-fit mechanism. The elastic member and buckle system provides both rapid assembly and dependable connection through its spring-loaded engagement design, achieving high productivity without sacrificing connection reliability.
3Manufacturing precision
If tools are required for antenna module installation, then connection precision is improved, but safety risk increases
Solution Approach 1:
The patent extracts and eliminates the need for external tools (screwdrivers, wrenches) from the assembly process. By integrating the fastening function directly into the antenna module structure through the buckle and elastic member system, the harmful factor of tool-based operations and associated safety risks are completely removed while maintaining precise connection through the designed snap-fit geometry.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quicker and safer maintenance or replacement of antenna modules by eliminating the need for tools and reducing the risk of falls from elevated positions, thereby improving operational efficiency and safety.
Implementation Method 1
The fastener includes a buckle and an elastic member respectively connected to the buckle and the second connection portion of the waveguide. When the buckle is pushed out of the fastening recess by the unlocking assembly, the second connection portion is separable from the first connection portion.
