Solution Overview

Problem

Conventional torque tools with illuminator-based warnings face challenges in providing precise and convenient torque value indications, as users struggle to determine if the target torque has been reached due to large percentage ranges or the need to count multiple illuminators, leading to potential tool damage or insecure workpiece fixation.

Innovation Solution

A torque tool with a segmented warning system featuring a primary warning unit and secondary warning unit, using luminescent colors and multiple illuminators to provide staged light warnings within defined intervals, allowing users to quickly and accurately determine the torque value's relation to a predetermined value.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If an interval indication method with different color lights is used to show percentage ranges, then users can know the general torque range, but the percentage range of each interval is relatively large, reducing indication precision

Engineering Contradiction:

Improveease of reading torque rangeVSAvoidprecision of torque percentage indication

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The warning assembly is segmented into a primary warning unit with different luminescent colors for broad intervals and a secondary warning unit with multiple illuminators for fine-grained percentage stages within each interval. This segmentation allows the primary unit to provide easy-to-read color-coded ranges while the secondary unit provides precise percentage indication through staged illuminator activation.

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If multiple illuminators are used to indicate each 10% torque increase, then the torque value indication is more accurate, but the number of illuminators is relatively large, making it inconvenient for users to check

Engineering Contradiction:

Improveprecision of torque percentage indicationVSAvoidconvenience of checking torque percentage

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The warning system is divided into a primary warning unit that displays broad torque ranges using different luminescent colors (easy to read) and a secondary warning unit that provides detailed percentage stages within each range (precise but fewer elements). This segmentation reduces the total number of illuminators needed while maintaining both precision and ease of reading.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the warning assembly serve different functions: the primary warning unit uses color changes for quick range identification, while the secondary warning unit uses staged illuminator activation for precise percentage indication within each color range. This local differentiation optimizes both precision and ease of operation.

Inventive Principle:

Principle #3Local quality

3Measurement precision

If a numerical indication on an indicator screen is used to show torque value, then the torque value can be precisely displayed, but the user is distracted to watch the indicator screen while operating the tool, reducing convenience and safety

Engineering Contradiction:

Improveprecision of torque value displayVSAvoidconvenience and safety of operation

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The numerical indicator screen is replaced with an optical warning system using luminescent colors and staged illuminators. This substitution provides precise torque value indication through visual cues that are immediately perceivable during operation, eliminating the need for users to focus on a digital display and maintaining both precision and operational convenience.
