Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple optical patterns are detected and decoded simultaneously, then scanning efficiency is improved, but processing power requirements increase

Engineering Contradiction:

Improvescanning efficiencyVSAvoidprocessing power

Core Design Contradiction:

ProductivityVSPower

Solution Approach 1:

The patent segments the scanning process into distinct phases: detection phase where multiple optical patterns are identified, and decoding phase where they are processed. This segmentation allows the system to manage processing power by handling detection and decoding separately, improving overall scanning efficiency without overwhelming processing resources.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary detection of multiple optical patterns before full decoding. By detecting patterns first and then decoding them in a controlled manner, the system prepares data in advance, reducing the computational burden during actual decoding and improving scanning efficiency.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If user input is required to adjust the count of optical patterns, then accuracy is improved, but ease of operation decreases

Engineering Contradiction:

Improvecounting accuracyVSAvoiduser interaction complexity

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent implements feedback mechanisms where the system presents detected optical patterns to the user and allows verification or correction of the count. This feedback loop improves counting accuracy by enabling user validation while maintaining ease of operation through intuitive interaction interfaces.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system provides self-service capabilities by automatically detecting and counting optical patterns, then allowing optional user adjustment. The default automatic counting serves most cases, while user input is only required when corrections are needed, balancing accuracy with ease of operation.

Inventive Principle:

Principle #25Self-service
