Solution Overview

Problem

The assembly and disassembly of two-piece upper and lower motherboards in a COM-HPC structure are inconvenient due to potential connector damage during electrical connection and difficulty in separation.

Innovation Solution

A fixing auxiliary device with support frames, support members, and elastic members that facilitate secure attachment and easy detachment of the motherboards, using threaded, magnetic, or snap-fit connections, along with elastic components to stabilize and guide the components during assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If two-piece upper and lower motherboards are used to achieve compact layout, then occupied space is reduced, but connector damage risk increases during electrical connection

Engineering Contradiction:

Improveoccupied spaceVSAvoidconnector damage risk

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The patent applies preliminary action by providing guide pillars on the first motherboard that align with guide holes on the second motherboard before electrical connection. This pre-alignment ensures that connectors engage properly without collision, preventing damage while maintaining the compact two-piece structure. The guide pillars are positioned to guide the insertion process, so the compact layout is achieved without increasing connector damage risk.

Inventive Principle:

Principle #10Preliminary action

2Volume of moving object

If two-piece upper and lower motherboards are used to achieve compact layout, then occupied space is reduced, but separation difficulty increases during disassembly

Engineering Contradiction:

Improveoccupied spaceVSAvoidseparation difficulty

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The patent applies segmentation by dividing the connection system into distinct functional elements: guide pillars for alignment, connectors for electrical connection, and fastening structures for secure attachment. The guide pillars are detachably connected to the first motherboard, allowing them to be separated independently. This segmentation enables easy separation during disassembly while maintaining the compact two-piece structure during operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses guide pillars as intermediary elements between the first and second motherboards. These pillars provide alignment guidance during assembly and can be easily detached during disassembly, serving as a mediator that facilitates both secure connection and easy separation. The intermediary structure allows the compact layout to be maintained while operation remains simple.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If guide pillars are detachably connected to first motherboard, then alignment guidance is provided, but device complexity increases

Engineering Contradiction:

Improvealignment guidanceVSAvoidstructure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The guide pillars serve multiple functions: they provide alignment guidance during assembly, act as structural support elements, and enable easy separation during disassembly. By making the guide pillars detachably connected rather than permanently fixed, the same structure achieves both guidance functionality and simplified disassembly without significantly increasing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A fixing auxiliary device includes a support frame, an elastic member, and a plurality of first support members. The first support member includes a first segment, a second segment, and a third segment which are connected in sequence. The third segment is detachably connected to the support frame, the first segment is configured to extend into a first component. An end of the second segment facing away from the third segment includes a first stop surface configured for stopping the first component from moving towards the support frame. The elastic member is configured to provide an elastic force to a second component to press against the support frame.
