Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional input devices (keyboards, mice, joysticks) are used, then device simplicity is maintained, but gesture detection capability and user immersion in virtual environments deteriorates
Solution Approach 1:
The patent replaces traditional mechanical input devices with a magnetic field-based detection system. Magnetic generators create magnetic fields that are detected by magnetic sensors, eliminating the need for mechanical components like keyboards, mice, or joysticks. This substitution enables contactless gesture detection while maintaining system simplicity through non-mechanical operation.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary between the user's hand gestures and the detection system. Magnetic generators embedded in the wearable object create magnetic fields that respond to hand gestures, and magnetic sensors detect these field changes. This intermediary mechanism enables indirect detection of gestures without direct mechanical contact.
2Measurement precision
If magnetic sensors and generators are disposed on the wearable object, then gesture detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges the magnetic generators and magnetic sensors onto a single wearable object. This integration allows the wearable object to both generate magnetic fields and detect their changes, creating a self-contained gesture detection system. The merging of these components simplifies the overall system architecture while maintaining high detection accuracy through the close proximity of sensors to the magnetic field sources.
