Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional methods using tables, mobile phone apps, or formulas are used to set grinding angle, then grinding angle can be obtained, but the process requires relatively exact measurements, a certain level of skill and experience, and is complex

Engineering Contradiction:

Improvegrinding angle measurement precisionVSAvoidsetting process complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary device (the grinding angle setting device with indicator and scale) that mediates between the support means adjustment and the grinding angle determination. This intermediary translates the complex relationship between support position and grinding angle into a simple visual indication, eliminating the need for users to perform measurements or calculations themselves

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical measurement and calculation process with a visual indication system. Instead of requiring users to mechanically measure distances and calculate angles using formulas or apps, the system uses an indicator pointer and scale to directly display the grinding angle, substituting complex mechanical operations with simple visual reading

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If traditional methods requiring exact measurements and calculations are used, then grinding angle can be determined, but the process requires skill and experience leading to uncertainties and potential errors

Engineering Contradiction:

Improvegrinding angle accuracyVSAvoidoperational simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device performs the measurement and calculation functions automatically through its mechanical linkage and indicator system. The support means adjustment automatically moves the indicator along the scale to show the correct grinding angle, making the system self-servicing and eliminating the need for user skill in measurement and calculation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent implements a feedback mechanism where the position of the support means is continuously reflected by the indicator position on the scale. This real-time visual feedback allows users to verify the grinding angle setting without needing to understand the underlying measurements or calculations, improving both reliability and ease of operation

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If multiple components like tool setter with holes and shoulders are used to adjust support position and tool protrusion, then grinding parameters can be set, but the device complexity increases

Engineering Contradiction:

Improvegrinding parameter adjustabilityVSAvoidsetting device complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal setting device that handles multiple grinding parameters (support position and tool protrusion) through a single integrated mechanism. The indicator-scale system serves multiple functions by showing different grinding angles for different configurations, eliminating the need for separate adjustment mechanisms for each parameter

Inventive Principle:

Principle #6Universality (Multi-functionality)
