Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Circuit boards used in OCP infrastructure are prone to bending and cracking due to mechanical stress, leading to increased material, assembly, and manufacturing costs, necessitating a solution to enhance mechanical strength and stability while maintaining installation convenience.
Innovation Solution
A fixing device comprising a circuit board with a peripheral recess, a fixing bracket with lateral arms and guiding rails, and a latching structure that includes a rotating arm and fixing pillar to securely attach an expansion unit, along with ribs for additional support and heat resistance, allowing for improved mechanical strength and easy installation/detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the circuit board is made larger to accommodate OCP expansion slots, then the storage and calculation abilities are improved, but the circuit board becomes more prone to bending and cracking due to increased size and mechanical stress
Solution Approach 1:
The fixing bracket is divided into multiple functional parts: a board for mounting, two lateral arms extending from opposite sides of the board, and two guiding rails on the lateral arms. This segmentation allows each part to perform its specific function - the lateral arms provide structural support while the guiding rails guide the expansion unit, collectively enhancing the circuit board's mechanical strength without limiting expansion capability
Solution Approach 2:
The fixing bracket integrates multiple functions into a single component: it provides structural support through the board, lateral reinforcement through the lateral arms, and guidance through the guiding rails. By merging these functions into one integrated bracket, the design strengthens the circuit board while maintaining expansion capability without requiring multiple separate components
2Quantity of substance
If the circuit board is made larger to fit OCP specifications, then the storage infrastructure capacity is improved, but the circuit board becomes more susceptible to cracking during assembly and operation
Solution Approach 1:
The fixing bracket is pre-installed on the circuit board before the expansion unit is installed. The lateral arms and guiding rails are positioned in advance to provide structural reinforcement and guidance pathways, preventing the circuit board from bending or cracking during the subsequent assembly process when the expansion unit is inserted
3Ease of manufacture
If a traditional fixing method is used, then the assembly process is simple, but the circuit board lacks sufficient mechanical strength and stability
Solution Approach 1:
The guiding rails on the lateral arms provide dynamic guidance for the expansion unit during insertion and removal. The rails allow controlled movement along the insertion slot while maintaining structural support, enabling easy assembly and disassembly without compromising the circuit board's mechanical stability

AI summary
A fixing device includes a circuit board, an insertion slot, and a fixing bracket. The circuit board has a peripheral recess, and the insertion slot is disposed on the circuit board. The fixing bracket is fixed in the peripheral recess, and the fixing bracket has a board, two lateral arms, and two guiding rails. The two lateral arms are connected to two corresponding sides of the board, and the two lateral arms are integrally formed from the board. In addition, the two guiding rails are respectively disposed at the two lateral arms, in which the two guiding rails extend towards the insertion slot.
