Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing electrical component sockets cause damage to terminals and scratches on the upper surface of electrical components during testing due to oblique downward forces applied by the cover member.

Innovation Solution

The electrical component socket incorporates a movable support member, a lever member, a link member, and interlocking mechanisms that ensure a downward force is applied to the cover member, preventing lateral displacement and rubbing against the component.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If the cover member pivots in a closing direction about the pivot shaft to press the electrical component, then the electrical component is pressed, but a force in an oblique downward direction acts on the electrical component causing lateral displacement and terminal damage

Engineering Contradiction:

Improvepressing forceVSAvoidlateral displacement and terminal damage

Core Design Contradiction:

ForceVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a pivot shaft as an intermediary component between the cover member and the electrical component. The pivot shaft serves as a fulcrum that transforms the oblique downward force into a vertical pressing force, mediating the force transmission to eliminate harmful lateral displacement while maintaining effective pressing action on the electrical component.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent inverts the traditional pivot mechanism by positioning the pivot shaft at the base end of the cover member rather than at the leading end. This inversion changes the force vector direction, causing the cover member to press downward vertically on the electrical component rather than applying an oblique force, thereby preventing terminal damage and lateral displacement.

Inventive Principle:

Principle #13The other way round (Inversion)

2Force

If the cover member pivots in a closing direction to press the electrical component, then pressing action is achieved, but the cover member rubs against the upper surface causing scratches

Engineering Contradiction:

Improvepressing forceVSAvoidscratches on upper surface

Core Design Contradiction:

ForceVSObject-generated harmful factors

Solution Approach 1:

The patent inverts the pivot point location from the leading end to the base end of the cover member. This inversion fundamentally changes the contact geometry between the cover member and electrical component, ensuring that the cover member presses downward on the top surface without rubbing against the upper surface, thereby preventing scratches while maintaining effective pressing action.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent applies local quality by ensuring that only the base end of the cover member contacts the electrical component at a specific localized point on the top surface. The pivot shaft positioning creates a precise contact point that applies pressure without sliding or rubbing, concentrating the force application in a way that prevents surface damage while achieving the pressing function.

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If a pivot shaft is introduced to change the force direction, then lateral displacement is suppressed, but the device complexity increases

Engineering Contradiction:

Improvelateral displacementVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the pivot shaft to serve multiple functions simultaneously: it acts as a fulcrum for the cover member, a support element, and a force direction transformer. This multi-functionality allows the single component to address lateral displacement issues while integrating seamlessly into the existing socket structure, minimizing the need for additional separate components and reducing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the pivot shaft function with the existing cover member structure, combining the support and pivoting functions into a unified mechanism. The pivot shaft is integrated with the socket main body and cover member assembly, creating a compact combined structure that achieves lateral displacement suppression without adding significant complexity to the overall device architecture.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Provided is an electrical component socket including: a movable support member that is provided on a side of one end of a main body so as to be movable in an up-down direction; a cover member of which a side of a base end is pivotably coupled to a support portion of the movable support member; a lever member of which a side of a base end is pivotably coupled to the side of the one end of the main body; and a link member of which a side of a base end is pivotably coupled to a side of another end of the main body. The cover member is locked to a locked portion of the link member by a closing operation of the cover member. The locked portion and the support portion push down the cover member by a closing operation of the lever member.
