Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a computer mouse with scroll wheel is used for rotation-based input, then rotation control is achieved, but ease of operation deteriorates on certain electronic devices
Solution Approach 1:
The patent replaces the mechanical scroll wheel system with an image processing-based detection system. Instead of relying on a physical scroll wheel, the system captures images of the physical object (e.g., a cup or container) and detects rotation through image analysis, substituting mechanical input with optical detection and processing.
Solution Approach 2:
The system achieves universality by working with any physical object that can be captured by the device's camera, not requiring a specialized mouse or controller. The same image processing mechanism works regardless of the object's shape, size, or material, making the rotation input method universally applicable across different electronic devices and usage scenarios.
2Adaptability or versatility
If image processing is used to detect physical object movement, then adaptability improves, but device complexity increases
Solution Approach 1:
The system leverages the electronic device's existing camera and processing capabilities to perform the detection function. Rather than adding dedicated hardware for rotation detection, the device uses its own built-in components (camera, processor) to self-service the detection task, minimizing additional complexity while maintaining adaptability.
Solution Approach 2:
The system creates a digital copy (image) of the physical object and analyzes the sequence of copies to detect movement. By working with image data rather than direct physical sensing, the system simplifies the detection process and reduces hardware complexity while maintaining the ability to detect rotation of various physical objects.
