Solution Overview

Problem

Conventional server chassis handling is inconvenient due to screw fixation requiring time-consuming unscrewing and engagement structures that are not adaptable to various rack heights, making it difficult to easily withdraw or replace chassis in rack servers.

Innovation Solution

A handle structure with a holding member, press member, and adjustable hook that includes a clasp portion and fastening holes, allowing for easy engagement and disengagement with retaining holes on the rack, facilitating easy withdrawal and adjustment to accommodate different rack heights.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the chassis is fixed by screws fastened on two outer sides, then the chassis can be securely fixed to the rack, but the screws have to be unfastened one by one which is time-consuming and inconvenient

Engineering Contradiction:
Improvefixation strengthVSAvoidtime for removal
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The fixation system is segmented into multiple independent fastening points (first fastening element at the end of the press member, and second fastening element at the clasp portion), allowing simultaneous or sequential engagement with multiple retaining holes. This segmentation enables the entire fixation process to be completed through a single pressing action rather than multiple individual screw operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The press member acts as an intermediary mechanical element that translates a single pressing force into simultaneous engagement of both the first and second fastening elements with their respective retaining holes. This intermediary mechanism converts one simple user action into a complex multi-point fixation event, dramatically reducing the time and effort required for chassis removal.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If an engagement structure is used to fix the chassis to the rack, then the time and labor for unfastening are reduced, but the engagement structure cannot be applied to various rack servers having various heights

Engineering Contradiction:
Improvetime for unfasteningVSAvoidadaptability to various rack heights
Core Design Contradiction:
Loss of timeVSAdaptability or versatility

Solution Approach 1:

The press member is designed with rotational freedom around the pivot portion, making it a dynamic component that can adjust its orientation and position. This dynamic characteristic allows the press member to adapt to different rack heights and configurations while maintaining the quick-release functionality. The clasp portion can be positioned at different angles to engage with retaining holes at various vertical positions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The handle structure serves multiple functions: it provides secure fixation through dual fastening elements, enables quick release through the press member mechanism, and adapts to various rack heights through the adjustable clasp portion. This multi-functional design makes the system universally applicable to different rack server configurations while maintaining operational efficiency.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If a fixed-length hook is used in the handle structure, then the structure is simple, but it cannot accommodate various rack heights

Engineering Contradiction:
Improvehandle structure complexityVSAvoidadaptability to various rack heights
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The press member is designed with rotational freedom around the pivot portion, making it a dynamic component that can adjust its orientation and position. This dynamic characteristic allows the press member to adapt to different rack heights and configurations while maintaining the quick-release functionality. The clasp portion can be positioned at different angles to engage with retaining holes at various vertical positions.

Inventive Principle:

AI summary

A handle structure includes a holding member (110), a press member (130), and a hook (150). The holding member (110) includes a holding portion (112) and a space (114) formed in the holding portion (112). The press member (130) includes a press portion (134) and a plurality of adjustment holes (136). The press portion (134) is movably disposed in the space (114). The adjustment holes (136) are disposed on the other end of the press member (130) opposite to the press portion (134). The hook (150) includes a clasp portion (152) and at least one fastening hole (154). The fastening hole (154) is adjustably positioned corresponding to any of the adjustment holes (136), and the clasp portion (152) is movable along with the movement of the press portion (134), wherein the clasp portion (152) protrudes out of the holding member (110). The hook (150) moves by pressing the press portion (134).
