Tool-Free Latch Actuation for Enclosure Lid Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical component enclosures require the use of specialized tools, such as screwdrivers, to actuate small latch components for lid removal, making the process time-consuming and complicated due to the need for precise tool manipulation.
Innovation Solution
The electrical component enclosure assembly incorporates latch actuation elements that allow for manual actuation without tools, providing physical feedback to ensure proper latch engagement and disengagement, simplifying lid removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If small latch components are used to secure the lid, then the enclosure provides secure retention, but the latch components cannot be actuated by hand and require specialized tools
Solution Approach 1:
A flat, bladeless actuation element is introduced as an intermediary between the user's hand and the latch component. This actuation element extends from the lid and can be manually pressed to actuate the latch, eliminating the need for specialized tools while maintaining secure lid retention through the original small latch components
2Reliability
If multiple latches are used on the enclosure, then the lid security is improved, but the time required to actuate all latches increases
Solution Approach 1:
Multiple actuation elements are combined into a single integrated structure that can simultaneously actuate multiple latch components. The actuation elements are configured so that a single user action can disengage all latches at once, maintaining high lid security through multiple latches while dramatically reducing the time required for lid removal
3Device complexity
If precise tool manipulation is required to actuate latches, then the latch mechanism remains compact, but the operational complexity increases
Solution Approach 1:
Instead of requiring the user to manipulate a small tool precisely to actuate the latch, the design is inverted so that the latch actuates the user-friendly actuation element. The actuation elements extend outward from the lid with sufficient length and appropriate stiffness to be easily pressed by hand, eliminating precise manipulation requirements while keeping the latch mechanism compact
