Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If external equipment and third-party assistance are used to monitor bow performance parameters, then measurement precision is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:

Improvebow performance parameter measurementVSAvoidmonitoring system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple sensors (draw weight sensor, draw length sensor, arrow speed sensor) and the performance module into an integrated monitoring system that is mechanically coupled to the bow components. This merging eliminates the need for separate external equipment while maintaining measurement precision.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The monitoring system is designed to be self-contained, with sensors automatically detecting bow performance parameters and the performance module independently processing and displaying data. The system serves itself without requiring third-party assistance or external equipment.

Inventive Principle:

Principle #25Self-service

2Measurement precision

If external equipment and third-party assistance are used to monitor bow performance parameters, then measurement precision is improved, but ease of operation worsens

Engineering Contradiction:

Improvebow performance parameter measurementVSAvoidmonitoring system operation

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The sensors automatically detect and the performance module independently processes bow performance parameters without requiring external equipment or third-party assistance. The system operates autonomously, improving ease of use while maintaining measurement precision.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The performance module provides real-time feedback by displaying measured parameters (draw weight, draw length, arrow speed) directly to the user through an integrated display. This immediate feedback eliminates the need for external equipment and makes the system easy to operate.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If multiple accessories with independent power supplies are added to the bow, then adaptability is improved, but device complexity worsens
