Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing structures for removable electronic devices, such as disk drive arrays, require complex components, leading to increased manufacturing costs and complicated manipulation.
Innovation Solution
A fixing structure comprising a handle body, a backplane, a screw member, and an elastic member, where the screw member is stopped by a mechanism within the handle body and extends through the backplane, allowing for easy attachment to a bay with reduced component complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional holder devices use complex components (combined screw, floating screw, screw sleeve, hand turn screw) to achieve holding and fixing functions, then the fixing reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple fixing components (holder body, backplane, screw member, elastic member) into an integrated assembly where the holder body and backplane form a unified structure. The elastic member is embedded within the holder body, and the screw member passes through both components, merging their functions into a single coordinated mechanism that achieves reliable fixing without requiring separate complex components
Solution Approach 2:
The holder body serves multiple functions simultaneously: it provides structural support, houses the elastic member, guides the screw member, and interfaces with both the electronic device and the bay. The backplane provides both mounting surface and structural reinforcement. This multi-functionality reduces the need for additional specialized components
2Strength
If conventional holder devices use multiple complex components for fixing, then the fixing strength is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The fixing mechanism is segmented into distinct functional modules: the holder body (with integrated elastic member), the backplane, and the screw member. Each module can be manufactured separately using standard processes, then assembled together. This segmentation allows each component to be optimized for its specific function while simplifying the overall manufacturing process compared to creating a single complex integrated component
Solution Approach 2:
The elastic member is designed to be self-contained within the holder body, providing automatic tension and positioning without requiring external adjustment mechanisms. The screw member self-guides through the aligned openings in the holder body and backplane, and the stopping mechanism automatically limits screw insertion depth. These self-service features eliminate the need for complex assembly procedures and specialized manufacturing processes
3Reliability
If conventional holder devices use complex fixing mechanisms, then the holding function is improved, but the ease of operation deteriorates
Solution Approach 1:
The holder device incorporates dynamic elements that automatically adapt during operation. The elastic member dynamically adjusts its tension as the screw member is inserted or removed, providing continuous holding force without requiring manual adjustment. The stopping mechanism dynamically limits screw insertion based on the electronic device's position, automatically preventing over-insertion without requiring operator intervention
Solution Approach 2:
The complex adjustment and control functions are extracted from the operator's tasks and embedded into the device structure itself. The stopping mechanism is built into the holder body's opening, automatically preventing over-insertion. The elastic member is pre-loaded within the holder body, automatically providing tension. This extraction of functions from manual operation to built-in device features greatly simplifies the user's interaction while maintaining reliable holding
