Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable device with control circuit, power circuit, and personal data device is created to provide audible messages, then emotional support and user well-being are enhanced, but device complexity increases
Solution Approach 1:
The patent combines multiple functional circuits (control circuit, power circuit, personal data device) into a single integrated keychain device, merging recording, storage, playback, and communication functions into one portable unit that can be carried on keys
Solution Approach 2:
The keychain device performs multiple functions simultaneously: it records audio messages, stores them in memory, plays them back through a speaker, and enables two-way wireless communication with external devices, making a single device serve diverse therapeutic and communication needs
2Ease of operation
If wireless communication capability is added for message presentation, then accessibility of encouragement messages is improved, but power consumption increases
Solution Approach 1:
The wireless communication and audio playback functions operate periodically or on-demand rather than continuously, activating the control circuit and personal data device only when message transmission or recording is needed, thereby reducing overall power consumption while maintaining accessibility
