Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If human judgment is used to determine whether an object is moved to the specified position, then the gameplay becomes less engaging and fun, but the detection accuracy and automation level remain low
Solution Approach 1:
The patent replaces manual human judgment with an automated optical detection system. The sensor array captures reflected light from the target object, and the processing circuit automatically analyzes color saturation values to determine positional accuracy, eliminating the need for human visual assessment while maintaining high detection precision.
Solution Approach 2:
The detection system performs self-assessment by automatically comparing the detected color saturation of the target object against predetermined thresholds. The system independently determines whether the object is at the specified position without requiring external human intervention, achieving self-service automation.
2Measurement precision
If human eyes are used to decide object position, then the detection accuracy is low and subjective, but the device complexity is minimal
Solution Approach 1:
The patent utilizes color saturation analysis to detect object position. Different positions of the target object reflect different amounts of light, resulting in varying color saturation values in the captured image. By measuring these color changes and comparing them to predetermined thresholds, the system achieves precise, objective position detection.
Solution Approach 2:
The patent replaces subjective human visual judgment with an automated optical measurement system. The sensor array and processing circuit objectively measure color saturation values and compare them against predetermined thresholds, eliminating human subjectivity and significantly improving detection accuracy and consistency.
3Ease of operation
If automated optical detection is implemented, then the fun and engagement of gameplay is enhanced, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces manual position verification with automated optical detection, allowing children to play without adult supervision for position checking. This substitution enhances gameplay ease and engagement while the system provides immediate automated feedback.
Solution Approach 2:
The optical sensor device serves multiple functions: detecting object position, determining color saturation, and providing gameplay feedback. This multi-functionality justifies the device complexity by consolidating multiple detection capabilities into a single integrated system that enhances overall gameplay experience.
