Pivoting Lock Mechanism for Computer Access Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locking and covering arrangements for computer desktops and workstations often require cumbersome dual locking mechanisms, such as padlocks and key locks, which are inconvenient and do not adequately prevent unauthorized access, as they allow users to pry open the cover despite being locked.
Innovation Solution
A computer cover retention bar integrated with a padlock and/or Kensington lock setup, featuring detents or hooks that ensure the cover remains fully closed when locked, preventing unauthorized access by decoupling the cover from the chassis only when the locking device is removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a padlock or Kensington lock is used alone, then the locking mechanism is simple, but the cover can still be pried open by users
Solution Approach 1:
The patent combines a retention bar with detents/hooks and a linkage mechanism with an external lock into a single integrated system. The retention bar is displaceable between a retracted position and an extended position, and the linkage connects the lock to the retention bar, creating a unified security mechanism that prevents both unauthorized locking and prying open of the cover.
Solution Approach 2:
The locking mechanism is divided into separate functional components: an external locking device (padlock or Kensington lock), a linkage mechanism, and a retention bar with detents. This segmentation allows each component to perform its specific function while working together as a coordinated system, where the linkage translates the locking action into retention bar movement.
2Reliability
If a dual locking arrangement (padlock plus key lock) is used, then security is improved, but the arrangement becomes cumbersome and inconvenient to manage
Solution Approach 1:
The patent merges the functions of multiple locking mechanisms into a single external lock interface. The external locking device controls both the linkage mechanism and the retention bar through one locking action, eliminating the need for separate key locks while maintaining enhanced security. The user interacts with only one lock, significantly improving convenience.
3Ease of operation
If the cover is removed through physical manipulations, then the cover can be opened, but the process is cumbersome and awkward
Solution Approach 1:
The retention bar is pre-positioned in the extended position during normal operation, maintaining the cover in a securely closed state. When the external lock is unlocked, the linkage automatically moves the retention bar to the retracted position, preparing the cover for easy removal. This preliminary positioning eliminates the need for awkward manual manipulation during the removal process.
4Reliability
If the retention bar is provided with detents or hooks, then the cover remains fully closed when locked, but the mechanism becomes more complex
Solution Approach 1:
Instead of using complex multi-point locking mechanisms to prevent cover separation, the patent inverts the approach by using a simple displaceable retention bar that, when extended with detents or hooks, naturally prevents the cover from being pried open. The complexity is minimized by using a single movable bar rather than multiple fixed locking points.

AI summary
A computer cover retention bar (or lock bar) is provided that is functionally integrated with a padlock and/or Kensington lock setup in such a way that full closure via the padlock and/or Kensington lock will ensure that the retention bar, itself provided with detents or hooks that themselves act to keep the cover fully closed with respect to a chassis or body of the desktop or workstation, cannot be moved. This then ensures that the locking action of a padlock or Kensington lock goes a measure beyond the norm, in that a cover can indeed remain fully closed without, e.g., affording unauthorized individuals from prying open the cover.
