Locking Quick-Release Pin Assembly with Concealed Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Equipment without holes to accommodate traditional locks poses a safety risk during maintenance, as quick-release pins can be easily removed, creating hazardous conditions.
Innovation Solution
A locking quick-release pin assembly featuring a cover with tabs that conceal the button portion of the pin, allowing locks to be secured through the tabs, preventing unauthorized removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional padlock is used, then the lock cannot be removed without the key providing security, but the equipment must have holes that accommodate the lock shaft which limits applicability
Solution Approach 1:
The quick-release pin assembly serves multiple functions: it acts as both a locking mechanism and a universal interface for various lock types (padlocks, combination locks, security tags). The assembly can be used on equipment with quick-release pin holes regardless of the specific lock type, making it universally applicable while maintaining security through the concealed button design
2Ease of operation
If a quick-release pin is used, then the assembly can be easily installed and removed, but anyone can remove it creating safety hazards
Solution Approach 1:
The cover acts as an intermediary between the quick-release pin button and the operator. It allows the pin to be installed easily while blocking unauthorized removal attempts. The cover with its locking mechanism mediates the interaction, permitting only authorized removal through proper locking/unlocking procedures while maintaining ease of installation
3Ease of operation
If the button portion is exposed, then the quick-release pin can be easily operated, but unauthorized removal becomes possible creating hazardous conditions
Solution Approach 1:
The cover provides different qualities to different parts of the assembly: the button area is concealed and protected within the cover body, while the tab areas remain accessible for locking operations. This local differentiation allows secure operation while preventing unauthorized button access, eliminating the hazard of unintended removal
