Pin-Detachment Guide Member for Glasses Side Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side shield fixing structures for industrial glasses are inconvenient to disassemble, prone to damage, and result in high error rates due to screw coupling schemes that require complex tool manipulation and can harm the glasses during assembly and disassembly.
Innovation Solution
A pin-detachment guide member is introduced, featuring a rotatable knob, detachable member, and operating groove, allowing the side shield to be easily fixed and removed from the glasses by screw coupling through upper and lower wings, ensuring secure attachment and convenient detachment without damaging the glasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a screw coupling scheme is used to fix the side shield to the temple of glasses, then the side shield can be firmly coupled to the glasses, but the assembly process becomes complex and prone to damage
Solution Approach 1:
The fixing member is divided into multiple components: a pressing support that contacts the temple, hooks that engage with through-holes in the side shield, and an elastic member that provides fixing force. This segmentation allows each component to perform its specific function independently, simplifying the overall assembly process while maintaining firm coupling.
Solution Approach 2:
Instead of using traditional screw threads that require rotational assembly, the invention uses hooks that are inserted into through-holes and an elastic member that is pressed to engage. The assembly process is inverted from a rotational screwing action to a linear pressing and hooking action, which is simpler and less prone to damage.
2Strength
If hooks are inserted into through-holes from the inside to fix the side shield, then firm coupling is achieved, but disassembly becomes very inconvenient
Solution Approach 1:
The elastic member automatically engages with the hooks when pressed, and the hooks automatically engage with the through-holes in the side shield. The system uses its own elastic force to both assemble and disassemble itself - pressing the elastic member assembles it, while releasing it allows natural elastic recovery to disassemble it, eliminating the need for complex tool manipulation.
3Ease of manufacture
If through-holes are formed in the temple of glasses to attach the side shield, then the side shield can be fixed, but the glasses become prone to damage
Solution Approach 1:
The through-holes are extracted from the temple of glasses and relocated to the side shield only. The fixing member's hooks engage with these holes in the side shield, while the pressing support contacts the temple surface without requiring holes in it. This extraction preserves the integrity of the glasses temple while still achieving firm attachment.
