Auto-Locking Enclosure Cover for Tamper-Resistant Burial Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underground enclosure covers are time-consuming to secure and may be susceptible to tampering if not properly bolted, posing a risk of unauthorized access.
Innovation Solution
An enclosure cover assembly with a latch assembly that automatically locks onto the enclosure box, featuring a spring-biased mechanism and a latch stop to ensure secure locking, and a cover removal tool for easy unlocking and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded bolt is used to secure the enclosure cover to the enclosure box, then the enclosure is more secure against tampering, but the time required to secure the cover increases
Solution Approach 1:
The latch assembly is pre-installed on the enclosure cover and automatically engages with the enclosure box when the cover is placed on the box. The spring mechanism is pre-loaded to provide automatic latching without requiring manual bolt tightening, thus eliminating the time-consuming securing process while maintaining security
Solution Approach 2:
The latch assembly is designed to automatically lock the enclosure cover to the box without human intervention. When the cover is installed, the latch assembly self-actuates through the spring mechanism to engage the locking position, providing secure fastening without requiring worker action to tighten bolts
2Reliability
If a threaded bolt is used to secure the enclosure cover, then the enclosure is more secure, but the ease of operation decreases
Solution Approach 1:
The latch assembly automatically performs the securing function when the cover is installed. The spring-loaded mechanism self-actuates to engage the latch in the locking position, eliminating the need for manual bolt tightening operations and significantly improving ease of operation while maintaining security
Solution Approach 2:
The complex operation of threading and tightening bolts is extracted from the securing process. The invention replaces manual bolt operations with an automatic latch mechanism that engages through simple cover placement, making the operation trivial while maintaining secure fastening
