Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer devices face challenges in achieving easy installation and disassembly of components while maintaining a hot-plugging function, necessitating a device that facilitates quick attachment and detachment while ensuring effective locking and unlocking mechanisms.
Innovation Solution
A locking device with a blocking element, fixing element, and operating element that allows for relative motion between the locking component and operating element, enabling secure attachment and detachment of components through a coordinated movement mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If components are designed for easy installation and disassembly, then ease of operation is improved, but locking reliability may deteriorate
Solution Approach 1:
The locking component is designed with movable elements that can dynamically transition between locked and unlocked states. The operating element moves relative to the locking component to engage or disengage locking protrusions, providing both secure locking when engaged and easy release when actuated.
Solution Approach 2:
The operating element serves as an intermediary between the user and the locking mechanism. It translates user input into locking component actuation, enabling easy operation while maintaining reliable locking through the intermediate mechanical advantage and controlled engagement.
2Reliability
If a locking mechanism is designed for secure attachment, then locking reliability is improved, but device complexity increases
Solution Approach 1:
Multiple locking functions are merged into a single integrated locking component that works with the blocking element and operating element. The locking protrusions and blocking features are combined in one assembly, reducing overall device complexity while maintaining secure attachment capability.
Solution Approach 2:
The locking mechanism incorporates self-aligning and self-latching features where the locking component automatically engages with the blocking element when components are assembled, and can be released by a simple operating element actuation, reducing the need for complex control systems.
3Productivity
If quick release mechanism is implemented, then productivity is improved, but locking reliability may worsen
Solution Approach 1:
The locking component is pre-positioned and spring-loaded or bias-mounted to automatically engage with the blocking element upon component assembly. This preliminary engagement ensures reliable locking is established before the component is fully installed, and quick release is achieved by simply reversing the assembly action.
