Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If QR codes or NFC tags are used to enable users to access information, then information accessibility is improved, but the interaction becomes unnatural and user experience deteriorates
Solution Approach 1:
The patent replaces optical (QR code) and electromagnetic (NFC) interaction systems with a mechanical bone conduction system. Users physically touch and rub the tag surface, generating mechanical vibrations that are transmitted through bone to the device, creating a more natural tactile interaction while maintaining information accessibility.
Solution Approach 2:
The patent introduces bone conduction as an intermediary mechanism between the user's finger and the device. The vibration signal serves as a mediator that carries information from the physical tag to the digital device through the user's bone structure, enabling natural interaction without requiring visual attention or complex electronic communication protocols.
2Loss of information
If NFC tags or QR code scanners are used, then information access is enabled, but power sources are required and costs increase
Solution Approach 1:
The patent makes the system self-powered by using the user's own mechanical energy from touching and rubbing the tag. The bone conduction mechanism converts this mechanical energy directly into detectable vibration signals, eliminating the need for external power sources in the tag itself while maintaining information access capability.
Solution Approach 2:
The patent replaces electronic power-dependent systems (NFC, QR scanning) with a passive mechanical system. The tag contains no active electronic components or power sources; instead, it relies on mechanical vibrations generated by user interaction, which are then detected and converted into usable signals by the device.
3Ease of manufacture
If traditional RFID tags are used, then cost is reduced compared to NFC, but functionality and information access capability are limited
Solution Approach 1:
The patent changes the detection parameter from electromagnetic field response (traditional RFID) to mechanical vibration frequency and pattern analysis. By encoding information in the temporal and spatial characteristics of vibrations generated when users rub different areas of the tag, the system achieves enhanced information access capability while maintaining the simplicity and low cost of passive tag construction.
Solution Approach 2:
The patent utilizes mechanical vibration as the core information transmission mechanism. Different regions of the tag generate distinct vibration patterns when touched, allowing encoding of multiple data points. This approach maintains the passive, low-cost nature of RFID tags while dramatically expanding functionality through vibration-based information encoding.
