Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional communication module handles are prone to damage during insertion and removal from host devices, especially in environments with limited clearance, and may obstruct movement or cause damage to the communication module or host device due to their inflexible design.

Innovation Solution

A handle design featuring a base, grasp, and hinge with a detent mechanism that allows the grasp to rotate from an extended position to a collapsed position upon application of a detent-releasing force, facilitating deformation without damage, and incorporating flexible connectors and recesses/protrusions for enhanced durability and clearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the handle is designed to be rigid for structural strength, then the handle can provide stable support during communication module operation, but the handle is prone to damage during insertion and removal from host devices, especially in environments with limited clearance

Engineering Contradiction:

Improvestructural strengthVSAvoiddamage resistance during insertion and removal

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The handle transitions from a static rigid structure to a dynamic system with multiple degrees of freedom. The hinge mechanism allows the handle to rotate between extended and collapsed positions, while the detent mechanism provides controlled stability during operation. This dynamic design enables the handle to adapt its rigidity based on operational requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The handle is divided into separate components: a base, a grasp portion, and a hinge mechanism connecting them. This segmentation allows each component to perform its specific function - the base provides mounting stability, the grasp portion provides user interface, and the hinge enables positional transitions - while collectively solving the contradiction between rigidity and damage resistance.

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If the handle is designed to be inflexible for maintaining extended position, then the handle provides stable support, but the handle obstructs movement or causes damage in environments with limited clearance

Engineering Contradiction:

Improvehandle position stabilityVSAvoidobstruction and damage in limited clearance environments

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The handle employs a dynamic design that allows it to switch between extended and collapsed positions. During communication module operation, the detent mechanism maintains the handle in a stable extended position. When clearance is limited, the handle can be collapsed to avoid obstruction, thus resolving the contradiction between stability and space requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The handle's effective length and position parameters are changed through the hinge mechanism. The handle can transition from an extended state (providing stable support) to a collapsed state (reducing space occupation). This parameter change capability allows the handle to adapt to different operational environments without causing harm.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If the handle is designed to allow free rotation for ease of manipulation, then the handle facilitates insertion and removal, but the handle becomes prone to damage during manipulation

Engineering Contradiction:

Improvemanipulation easeVSAvoiddamage resistance during manipulation

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The handle provides controlled movement through the hinge mechanism rather than free rotation. The detent mechanism creates discrete stable positions (extended and collapsed) that guide user manipulation. This dynamic control allows easy transition between positions while preventing uncontrolled movement that could cause damage.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The detent mechanism provides predetermined stable positions that cushion the handle during manipulation. When the user operates the handle, the detent ensures the handle settles into defined positions rather than experiencing uncontrolled movement, thereby preventing damage while maintaining ease of operation.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A communication module handle may include a base, a grasp, a hinge, and a detent. The hinge may connect the base and the grasp. The detent may be configured to maintain a position of the grasp relative to the base in an extended position. In response to the detent being subjected to a detent-releasing force, the detent may release the grasp from the extended position to a collapsed position. The grasp may be rotatable relative to the base by way of the hinge in the collapsed position.
