Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart home devices often rely on voice control, which can be inconvenient or impossible in certain situations, necessitating a non-voice control method for user interaction.
Innovation Solution
A control method and device utilizing a radar wave sensor to monitor user actions, allowing for the performance of corresponding functions by the home device, including distance recognition and body contour identification, with the ability to turn off power when the user is out of range and providing prompt information for unmatched actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice control is used for smart home devices, then control convenience is improved, but usability deteriorates when users cannot speak
Solution Approach 1:
The system implements multiple control modes including voice control and gesture control through radar wave sensors. The control device can switch between different control methods based on user needs, making it universally applicable whether the user can speak or not. The radar wave sensor detects gestures such as hand waving, pointing, and clapping to trigger corresponding device functions.
2Adaptability or versatility
If radar wave sensors are added for gesture control, then adaptability is improved, but device complexity increases
Solution Approach 1:
The radar wave sensor acts as an intermediary device that translates physical gestures into control signals for the smart home device. Instead of directly processing complex gesture data, the sensor serves as a mediator that converts various hand movements into standardized control commands, simplifying the overall system architecture while maintaining gesture control capability.
3Loss of energy
If distance recognition is implemented, then energy saving is improved, but measurement precision requirements increase
Solution Approach 1:
The system continuously monitors user distance through the radar wave sensor and provides feedback control. When the user moves beyond a predetermined distance threshold, the system automatically transitions to a low-power state or turns off. The feedback mechanism adjusts device operation based on real-time distance measurements, enabling energy saving while maintaining acceptable measurement precision through continuous monitoring rather than high-precision single-point measurement.
