Tool-Free Fixing Assembly for Circuit Board Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server component fixation methods, such as using screws or bolts, complicate installation, removal, and maintenance by requiring hand or power tools, leading to inefficient and troublesome processes.
Innovation Solution
A fixing assembly comprising a contact component, stoppers, and a trigger that allows for the installation and removal of circuit boards without tools, where the trigger pushes the stopper to secure the circuit board in place, preventing unwanted displacement during installation and removal of function units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fasteners (screws or bolts) are used to fix circuit boards, then the fixation is reliable and secure, but the installation, removal, and maintenance processes become complicated and require hand or power tools
Solution Approach 1:
The fixing assembly is divided into separate functional components: stoppers for positioning, contact components for actuation, and triggers for release. This segmentation allows the system to achieve reliable fixation through multiple stoppers while enabling tool-free operation through the trigger mechanism that releases the stoppers sequentially.
Solution Approach 2:
The contact component acts as an intermediary between the trigger and the stopper. When the trigger is pressed, it moves the contact component, which in turn pushes the stopper to change its position. This intermediary mechanism translates the simple trigger action into the complex motion required for secure, tool-free fixation and release.
2Reliability
If conventional fasteners (screws or bolts) are used to fix circuit boards, then the fixation is secure, but the installation and maintenance processes become time-consuming and inefficient
Solution Approach 1:
The stoppers are pre-positioned in a blocking state that automatically engages with the circuit board upon insertion. This preliminary positioning ensures secure fixation without requiring additional fastening actions, while the trigger mechanism is pre-configured for rapid release, dramatically improving installation and maintenance efficiency.
Solution Approach 2:
The fixing assembly transitions from a static fastener system to a dynamic system where stoppers can move between engaged and disengaged states. The trigger mechanism enables rapid state changes, allowing the system to maintain secure fixation during operation while enabling quick release for maintenance, thus improving productivity.
3Ease of operation
If a trigger mechanism is used to push stoppers for tool-free installation, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The fixing assembly is designed to be self-servicing through the trigger mechanism. Once the trigger is pressed, the contact component automatically pushes the stopper into the correct position without requiring external tools or complex adjustment procedures. This self-service capability simplifies operation despite the increased structural complexity.
Solution Approach 2:
Multiple functions are merged into integrated components: the contact component serves both as a transmission element and a positioning element, while the stopper combines positioning and locking functions. This merging reduces the number of separate parts needed, thereby reducing overall device complexity while maintaining tool-free operation capability.
