Solution Overview

Problem

Existing force detection devices for welding points suffer from accuracy issues due to irregular welding point appearances and surface scratching during detection, especially when the detection finger directly contacts the welding points.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the detection finger directly contacts the welding points to detect welding strength, then the detection process is simple, but the accuracy is affected by irregular welding point appearances and surface scratching occurs

Engineering Contradiction:

Improvedetection process simplicityVSAvoiddetection accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent introduces a comb tooth component as an intermediary between the detection finger and the welding points. The comb teeth contact the welding points instead of the detection finger directly, eliminating surface scratching while the regular comb tooth structure provides consistent contact geometry for accurate detection regardless of welding point appearance variations

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If the detection finger directly contacts the welding points, then the device structure is simple, but surface scratching occurs and detection accuracy decreases

Engineering Contradiction:

Improvedevice structure simplicityVSAvoidsurface scratching

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The comb tooth component serves as a mediator that transfers the detection force from the detection finger to the welding points. This intermediary structure prevents direct contact between the detection finger and welding points, thereby eliminating surface scratching while maintaining a relatively simple overall device structure

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The comb tooth component is designed with specific geometric features (comb teeth with predetermined spacing and dimensions) that create a standardized contact pattern with the welding points, ensuring consistent detection conditions regardless of variations in welding point appearance

Inventive Principle:

Principle #32Color changes

3Device complexity

If the detection finger directly contacts irregular welding points, then no additional components are needed, but detection accuracy is compromised

Engineering Contradiction:

Improvenumber of componentsVSAvoidwelding strength detection accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The comb tooth component acts as an intermediary that standardizes the contact interface between the detection system and the welding points. The regular comb tooth structure compensates for irregularities in welding point appearance by providing a geometrically consistent contact pattern, thereby improving detection accuracy

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The comb tooth component transforms the detection interaction by changing the contact parameters - instead of direct finger-to-welding-point contact with variable geometry, the system uses comb teeth with controlled spacing, width, and height parameters that ensure consistent contact conditions for accurate detection

Inventive Principle:

Principle #35Parameter changes

AI summary

A comb tooth component for detecting a welding strength of a welding point of a row of welding points includes a connection block, and a row of elastic arms. The row of elastic arms is connected to one side of the connection block. The row of elastic arms has a comb tooth shape. The row of elastic arms extends along a longitudinal direction and is arranged in a row in a transverse direction perpendicular to the longitudinal direction. End portions of the row of elastic arms are arranged alternately with the row of welding points. The row of elastic arms sequentially push the row of welding points under a push of a transversally moving detection finger to detect the welding strength of the row of welding points.
