Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If wearable devices are designed with compactness, portability, and low power consumption, then device characteristics are improved, but interaction capability deteriorates
Solution Approach 1:
The patent replaces traditional mechanical touch interfaces with electromagnetic wave-based interaction. The receiving apparatus detects electromagnetic waves (such as radio waves) that carry interaction information, eliminating the need for physical buttons, screens, or other mechanical components, thus achieving compactness while maintaining interaction capability
Solution Approach 2:
The patent introduces electromagnetic waves as an intermediary carrier between the user and the wearable device. Instead of direct mechanical contact, the user's body (particularly the hand) serves as a conduit to receive and transmit electromagnetic wave signals, enabling interaction without physical interface components
2Volume of moving object
If wearable devices are designed with compactness and portability, then device characteristics are improved, but interaction efficiency deteriorates
Solution Approach 1:
The receiving apparatus is designed to detect multiple types of electromagnetic waves and perform various interaction functions through a single component. The same apparatus can detect different wave characteristics to identify various interaction modes (tapping, rubbing, sliding), eliminating the need for multiple specialized interfaces and improving interaction efficiency
3Use of energy by moving object
If wearable devices are designed with low power consumption, then energy efficiency is improved, but interaction capability deteriorates
Solution Approach 1:
The receiving apparatus operates in a periodic detection mode, continuously monitoring for electromagnetic waves but activating full processing only when waves are detected. This allows the device to maintain low power consumption during idle states while quickly responding to interaction signals when needed
Solution Approach 2:
The user's body itself serves as part of the interaction interface, utilizing the natural electromagnetic properties of the human body to receive and transmit signals. This eliminates the need for additional powered components in the interaction interface, reducing overall power consumption while maintaining interaction capability
