Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws or thermal melting are used to fix the keyboard module to the housing, then the fixation is strong and reliable, but the assembly process is time-consuming and difficult to disassemble
Solution Approach 1:
The engagement structure is divided into multiple components: a mounting hole, an inclined portion, and an abutting portion. This segmentation allows the keyboard module to be fixed through a simple insertion motion that engages these separate elements, eliminating the need for time-consuming screw fastening or thermal melting processes while maintaining reliable fixation.
Solution Approach 2:
Instead of using traditional fastening methods where the fastener is actively driven into place (screws being tightened or thermal melting being applied), this invention inverts the approach by having the mounting structure passively engage the keyboard module through the inclined and abutting portions during a simple insertion motion, making both assembly and disassembly quick and easy.
2Reliability
If screws or thermal melting are used to fix the keyboard module to the housing, then the fixation is secure, but the assembly process is complex and prone to mistakes
Solution Approach 1:
The invention inverts the traditional fastening approach by making the mounting structure passive rather than active. The inclined portion and abutting portion automatically engage the keyboard module during insertion, eliminating the complex multi-step processes of screw fastening or thermal melting that are prone to assembly mistakes, while maintaining secure fixation.
Solution Approach 2:
The engagement structure is designed to self-align and self-engage during the insertion of the keyboard module. The inclined portion guides the module into place, and the abutting portion automatically locks it securely, eliminating the need for complex assembly procedures or specialized tools that increase the risk of mistakes.
3Strength
If traditional fixation methods are used, then the keyboard module is securely fixed, but manufacturing costs increase due to time-consuming assembly
Solution Approach 1:
By segmenting the engagement structure into a mounting hole, inclined portion, and abutting portion, the invention enables rapid assembly through simple insertion motions. This eliminates the need for time-consuming screw fastening or thermal melting processes, reducing manufacturing cycle time and labor costs while maintaining secure fixation of the keyboard module.
Solution Approach 2:
The inverted approach where the mounting structure passively engages the keyboard module through inclined and abutting portions during simple insertion dramatically reduces assembly time and complexity compared to traditional active fastening methods, thereby lowering manufacturing costs while ensuring reliable fixation.
