Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional projecting mechanism is used, then the device structure is simple, but the projection process is unstable and produces large vibrations
Solution Approach 1:
The projecting mechanism is divided into multiple independent components: guide rod, slider, first elastic element, second elastic element, and mounting sleeve. Each component performs a specific function, with the guide rod providing guidance, the slider enabling linear motion, and the elastic elements providing shockproofing. This segmentation allows for optimized performance of each part while maintaining overall system reliability.
Solution Approach 2:
The patent implements a double-shockproof mechanism using two elastic elements (first and second elastic elements) positioned at different locations along the guide rod. These elastic elements provide beforehand cushioning by absorbing vibrations and shocks before they can affect the projection stability, thereby improving reliability without requiring a completely complex mechanism design.
2Object-affected harmful factors
If shockproof mechanisms are added to reduce vibrations, then projection stability improves, but device complexity increases
Solution Approach 1:
Two elastic elements are strategically positioned along the guide rod to provide beforehand cushioning against vibrations and shocks. The first elastic element is located between the slider and one end of the guide rod, while the second elastic element is located between the slider and the other end, ensuring vibration absorption occurs before harmful effects propagate through the system.
Solution Approach 2:
The mounting sleeve acts as an intermediary component that facilitates the connection between the second elastic element and the guide rod. It provides a stable mounting structure with guide holes and mounting holes, allowing the second elastic element to function effectively as a shockproofing element while maintaining structural integrity and reducing complexity.
3Stability of the object's composition
If multiple elastic elements and guide rods are used, then sliding stability and shockproof effect increase, but manufacturing complexity increases
Solution Approach 1:
The mounting sleeve is designed as a multi-functional component that simultaneously serves as a support structure, a guide for the second elastic element, and a connector between components. It features guide holes for the guide rod and mounting holes for the second elastic element, consolidating multiple functions into a single part that reduces assembly complexity while maintaining sliding stability.
Solution Approach 2:
The mounting sleeve acts as an intermediary that simplifies the connection between the second elastic element and the guide rod structure. By providing pre-formed mounting holes and guide holes, it facilitates easier assembly and manufacturing of the double-shockproof mechanism, reducing the complexity that would otherwise arise from directly connecting multiple components.
