Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrodes are wired to a chest band for biosignal measurement, then measurement reliability is improved, but mobility and breathing freedom deteriorate
Solution Approach 1:
The system is divided into separate modules: a sensor module with electrodes and armband, and a control module with processing electronics. This segmentation allows the electrodes to be positioned for reliable signal acquisition while the control module can be worn separately, improving mobility and comfort without compromising measurement reliability.
2Stability of the object's composition
If a chest band is used to secure electrodes, then electrode position stability is improved, but breathing restriction increases
Solution Approach 1:
The restrictive chest band is removed from the system. Instead, electrodes are attached to the armband or body using minimal restraint, extracting the harmful breathing restriction while maintaining electrode position stability through alternative securing methods.
3Reliability
If wiring is used to connect electrodes, then signal transmission reliability is improved, but mobility is reduced
Solution Approach 1:
The mechanical wiring system is replaced with wireless communication technology. The sensor module transmits biosignal data wirelessly to the control module, eliminating physical wires and significantly improving user mobility while maintaining reliable signal transmission through modern wireless protocols.
4Adaptability or versatility
If a modular detachable connector interface is used, then adaptability and ease of repair are improved, but device complexity increases
Solution Approach 1:
The connector interface is designed with universal functionality to handle multiple tasks: electrical connection for power and data transmission, mechanical attachment for module assembly, and signal synchronization. This multi-functionality reduces the need for separate specialized connectors, thereby limiting the increase in device complexity while achieving high adaptability.
