Resilient Lock Cover Plate for Chassis Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing chassis designs for electronic devices face challenges when trying to remove the back cover section due to interference from the hard disk drawer, which limits the ease of access and maintenance.
Innovation Solution
A chassis design incorporating a cover plate with a resilient lock and lead pins, where the resilient lock is fixed to the hard disk drawer and includes a positioning pin that latches and unlatches to secure and unlock the cover plate sections, allowing for smooth sliding and removal of the back cover section without disturbing other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a hard disk drawer is installed within the chassis, then storage capacity is improved, but the back cover section cannot be removed due to interference
Solution Approach 1:
The cover is divided into a front cover section and a back cover section that can be independently removed. The resilient lock with positioning pin allows the back cover section to be detached from the front cover section, enabling separate access to each portion without requiring removal of the entire cover assembly.
Solution Approach 2:
The resilient lock provides a dynamic locking mechanism that can transition between locked and unlocked states. The positioning pin can be inserted into or removed from the through hole in the resilient lock, allowing the back cover section to be securely fastened during normal operation and easily detached when maintenance is needed.
2Ease of repair
If the back cover section is made removable for maintenance access, then ease of repair is improved, but the hard disk drawer may be disturbed
Solution Approach 1:
The cover assembly is segmented into independent front and back sections with the resilient lock mechanism enabling selective detachment of the back section. This segmentation allows maintenance personnel to access and service the back cover without affecting the front cover or the hard disk drawer, maintaining drawer stability during normal operation.
Solution Approach 2:
The resilient lock acts as an intermediary mechanism between the front and back cover sections. It provides a controlled interface that allows the back cover to be securely attached during normal use and easily detached for maintenance, while preventing any disturbance to the hard disk drawer through its intermediate locking action.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables easy removal and installation of the back cover section without interfering with the hard disk drawer, enhancing maintenance accessibility and operational efficiency.
Implementation Method 1
the resilient lock is resiliently deformed, the positioning pin is latched within the through hole

AI summary
A cover plate for locking a chassis includes a first cover section provided on top of the chassis, a second cover section provided on top of the chassis and having a positioning pin, and a resilient lock defining a through hole corresponding to the positioning pin. When the resilient lock is in a first position, the positioning pin is latched in the through hole, one end of the first cover section abuts against one end of the second cover section, and the cover plate is locked. When the resilient lock is in a second position, the positioning pin is removed from the through hole, the first cover section is slid toward the second cover section, and the cover plate is unlocked.
