Rotating Spacer Mechanism for Quick Circuit Board Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server designs have complex assembly and disassembly processes due to the height mismatch between circuit board connectors and housing partitions, requiring extra components for space adjustment, leading to increased costs and complexity.
Innovation Solution
A housing module with a spacer system that includes pivoting components and a locking mechanism, allowing the circuit board to be easily assembled and disassembled without detaching the spacer, by rotating the spacer within the housing to accommodate boards of varying heights and reducing friction through protruding and constraining portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the height of the connector is smaller than the distance between the bottom of the partition and the circuit board, then the circuit board can be freely assembled and disassembled, but the partition cannot provide sufficient support for taller components
Solution Approach 1:
The partition is designed with a rotatable section that can pivot between a horizontal position (providing support for tall components) and a vertical position (clearing the path for circuit board insertion and removal). This dynamic transformation allows the same structure to serve multiple functions depending on the operational state.
Solution Approach 2:
The partition is divided into multiple sections: a fixed section, a rotatable section, and a connecting section. This segmentation allows the rotatable portion to independently change orientation while the fixed portions maintain structural integrity and positioning.
2Strength
If the height of the connector or components on the circuit board is greater than the distance between the bottom of the partition and the circuit board, then sufficient support is provided, but the fixing components have to be unlocked to detach the partition, complicating the assembly process
Solution Approach 1:
The partition's rotatable section can dynamically change from a horizontal support position to a vertical clearance position, eliminating the need to unlock and remove the entire partition structure. This dynamic movement simplifies the assembly and disassembly process while maintaining component support when needed.
Solution Approach 2:
Instead of removing the partition to access the circuit board, the partition's rotatable section inverts its orientation (from horizontal to vertical) to clear the access path. This inversion approach maintains the partition's presence while enabling board replacement.
3Adaptability or versatility
If a detachable partition is used to accommodate different component heights, then adaptability is improved, but extra cost and complexity are introduced
Solution Approach 1:
The partition incorporates a rotatable mechanism that allows a single structure to adapt to different component heights by changing its orientation. This dynamic adjustment eliminates the need for multiple detachable partition configurations, reducing overall system complexity.
Solution Approach 2:
The partition structure serves multiple functions: it provides support for tall components when horizontal, and clears the access path when vertical. This multi-functionality eliminates the need for separate structures for different purposes, reducing complexity and cost.

AI summary
A housing module having a circuit board quick-assembling function is applied to an electronic device with a circuit board having a specific height. The housing module includes a housing, an spacer and two pivoting components. The housing includes a substrate and several lateral boards. The spacer includes a main body, two pivoting portions and a locking portion. The pivoting portions are disposed on corresponding sides of the main body, the locking portion stretches from a lower side of the main body and is fixed on the circuit board via an external fixing component. The pivoting portions pass through the lateral boards and are connected to the pivoting portions. While the circuit board slides relative to the substrate to push the spacer, the main body is rotated inside the housing via the pivoting portions to lift the lower side.
