Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing adapter assemblies for attaching modules like SSDs to electronic apparatuses face instability due to rotational forces, leading to potential separation of the module from the main member and instability in electrical connections.

Innovation Solution

An adapter assembly comprising a main member, a fixing member, a first interposing member with a male thread, and a second interposing member with a female thread and a rotation stopper, which securely attaches the module by preventing relative rotation between the second interposing member and the module, ensuring the male thread is screwed into the female thread without issues, thus stabilizing the connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the coupling member is firmly screwed into the opening so that the head is tightly pressed against the end of the module, then the module is securely held, but the module might be separated from the main member because of rotational force

Engineering Contradiction:

Improveholding forceVSAvoidconnection stability

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The invention divides the fastening function into two separate components: the coupling member for axial fastening and the rotation prevention member for rotational constraint. This segmentation allows each component to specialize in one function, preventing the conflict between holding force and rotational stability that plagued the single-coupling-member design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rotation prevention member acts as an intermediary component between the coupling member and the module. It receives the rotational constraint function from the coupling member's tightening action and translates it into a stable, rotation-free connection, mediating the conflict between tight pressing and rotational force.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the coupling member is loosely screwed, then rotational force is reduced, but the ground of the module via the main member becomes unstable

Engineering Contradiction:

Improveelectrical connection stabilityVSAvoidholding force

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

By separating the axial fastening function (coupling member) from the rotational constraint function (rotation prevention member), the system can achieve both strong holding force and stable electrical connection. The coupling member provides firm axial contact for grounding, while the rotation prevention member eliminates rotational instability without requiring excessive tightening force.

Inventive Principle:

Principle #1Segmentation

3Device complexity

If a single coupling member is used for both fastening and rotation prevention, then the device complexity is reduced, but the module may rotate or become unstable during attachment

Engineering Contradiction:

Improvenumber of componentsVSAvoidattachment stability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rotation prevention function is extracted from the coupling member and implemented as a separate rotation prevention member. This extraction allows the coupling member to focus solely on axial fastening while the dedicated rotation prevention member handles rotational constraints, improving overall attachment stability.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

An adapter assembly is used to attach a module having a mating interposed portion to an attachment member having a mating fixing portion. The adapter assembly comprises a main member having a fixed portion and an interposed portion, a fixing member, a first interposing member having a first interposing portion and a second interposing member having a rotation stopper and a second interposing portion. When the module is attached to the attachment member, the fixed portion is interposed and fixed between the fixing member and the mating fixing portion, and the mating interposed portion is interposed and held between the interposed portion pressed by the first interposing portion and the second interposing portion. During the attachment process of the module, the rotation stopper prevents the second interposing member from being rotated relative to the module.
