Equipment Cabinet Securing Assembly with Integrated Latch and Door Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing equipment cabinets with hinged sections lack an efficient and secure mechanism to lock the sections together, potentially allowing unauthorized access or accidental opening.
Innovation Solution
A securing assembly comprising a knob with a pocket and a latch, which can be rotated to engage or disengage the sections, and further secured by a door lock when the front door is closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a securing assembly is added to lock hinged sections together, then security and prevention of accidental opening are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated securing assembly: the latch mechanism for locking sections, the knob for operation, and the door lock integration all merge into one unit. This resolves the contradiction by achieving high security through functional integration rather than adding separate complex components, thereby improving reliability while controlling device complexity.
Solution Approach 2:
The securing assembly serves multiple purposes: it locks hinged sections together to prevent unauthorized access, prevents accidental opening, and integrates with the door lock system. This multi-functionality approach improves security comprehensively without requiring separate dedicated mechanisms for each function, thus improving reliability while avoiding proportional increases in device complexity.
2Reliability
If a securing assembly with latch and knob is implemented, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The securing assembly is designed to be operated directly by the user through the knob without requiring external tools or complex procedures. The latch engages and disengages automatically when the knob is rotated, providing self-service operation that maintains ease of use while achieving secure locking, thus resolving the contradiction between security and ease of operation.
Solution Approach 2:
The knob serves as an intermediary mechanism that translates simple user rotation into the engagement or disengagement of the latch. This intermediary design allows users to operate the secure locking system through a simple, intuitive motion rather than directly manipulating complex latch mechanisms, thereby maintaining ease of operation while achieving high security.
3Reliability
If the latch is engaged with the second section, then security is improved, but ease of operation deteriorates due to difficulty in opening
Solution Approach 1:
The latch mechanism is designed to be dynamically controllable through the knob rotation. When the knob is rotated, the latch transitions between engaged and disengaged states, allowing the system to switch between secure locked and easily opened states. This dynamic control resolves the contradiction by making the latch engagement reversible and controllable through simple user action.
Solution Approach 2:
Instead of requiring complex procedures to open the locked sections, the system inverts the approach: a simple rotation of the knob in the opposite direction automatically disengages the latch. This inversion principle allows authorized users to easily open the sections by reversing the locking action, maintaining security during normal operation while enabling easy authorized access.

AI summary
An equipment cabinet can include a cabinet section and a door supported by the cabinet section to be movable between an open orientation and a closed orientation. A door lock can be movable to a locked orientation to lock the door to the cabinet section, with the door in the closed orientation. A securing assembly that is coupled to the cabinet section can include a handle and a body. The door lock, in the locked orientation to lock the door to the cabinet section, can engage the body to block movement of the handle between the engaged orientation and the free orientation.
