Solution Overview

Problem

Identifying similar variations of vehicle parts with varying levels of completeness during manufacturing is challenging due to the difficulty in distinguishing between parts with the same number of teeth, leading to confusion among operators.

Innovation Solution

A gear identification tool with a segmented assembly of bodies having distinct gear teeth profiles and movable attachment structures that allow precise alignment and misalignment based on teeth profiles, enabling quick identification and sorting of vehicle parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If teeth counting is used to identify vehicle parts, then part identification can be performed, but the process becomes lengthy and time-consuming

Engineering Contradiction:
Improvepart identification accuracyVSAvoididentification time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The identification tool is divided into multiple bodies, with each body having gear teeth configured to mesh with a specific number of teeth on vehicle parts. This segmentation allows operators to quickly identify parts by matching the correct body to the part's tooth count, eliminating the need to count all teeth manually and significantly reducing identification time while maintaining accuracy.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple vehicle parts with the same number of teeth are produced, then manufacturing variety is achieved, but confusion among operators increases

Engineering Contradiction:
Improvepart varietyVSAvoidoperator confusion
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Each body in the identification tool set has unique local characteristics - specifically, gear teeth configured for meshing with a particular tooth count. This local differentiation allows operators to quickly distinguish between different part types by finding the matching body, eliminating confusion even when parts have similar overall characteristics but differ in tooth count.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If a comprehensive identification tool covering all part variations is created, then all parts can be identified, but device complexity increases

Engineering Contradiction:
Improvepart identification coverageVSAvoidtool structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Rather than creating one complex tool to handle all part variations, the solution segments the identification function across multiple simpler bodies. Each body handles a specific tooth count configuration, making individual bodies simple and easy to manufacture while collectively providing comprehensive coverage for identifying all part variations in the production line.

Inventive Principle:
Principle #1Segmentation

AI summary

A gear identification tool includes a segmented assembly including a first body and a second body movable relative to each other. The first and second bodies are coupled to each other by an attachment structure. The first body includes a plurality of first gear teeth configured to mesh with first predetermined gear teeth of a first gear. The first gear teeth have a first teeth profile. The second body includes a plurality of second gear teeth configured to mesh with second predetermined gear teeth of a second gear. The second gear teeth have a second teeth profile that is different than the first teeth profile.
