Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surface electromyography (sEMG) systems are used, then non-invasive monitoring is achieved, but measurement precision is insufficient for deep core and lower back muscles
Solution Approach 1:
The system divides the monitoring function into multiple specialized sensors placed at different locations on the body. Multiple EMG sensors are positioned on the core and lower back regions to capture signals from specific muscle groups, allowing non-invasive monitoring while improving precision through distributed measurement points.
Solution Approach 2:
The system introduces a sophisticated signal processing unit as an intermediary between the sensors and the user. This processor filters, amplifies, and analyzes the weak EMG signals from deep muscles, converting them into actionable feedback. The intermediary processing layer enables detection of deep muscle activity that would otherwise be obscured by noise.
2Measurement precision
If feedback is provided after activity completion, then data analysis accuracy is improved, but real-time performance optimization is lost
Solution Approach 1:
The system performs preliminary processing of EMG signals during the activity itself. The processor continuously analyzes muscle engagement patterns in real-time, preparing feedback information as the exercise occurs. This preliminary action enables immediate corrective feedback without waiting for post-activity analysis, allowing users to optimize their form during the actual workout.
Solution Approach 2:
The feedback mechanism operates continuously throughout the exercise rather than intermittently or only after completion. The system maintains constant monitoring and provides ongoing guidance, ensuring that useful feedback action continues without interruption. This continuous feedback loop allows users to make real-time adjustments while maintaining proper technique throughout the entire exercise session.
3Loss of information
If visual or auditory feedback methods are used, then information delivery is achieved, but user distraction during exercise increases
Solution Approach 1:
The system replaces traditional visual and auditory feedback mechanisms with haptic feedback through vibration motors. Instead of using light displays or sound signals that compete for the user's attention, the system uses tactile vibrations transmitted through the wearable device. This mechanical substitution delivers feedback information through the sense of touch, which does not distract from the visual and auditory focus required during exercise.
4Ease of operation
If basic fitness trackers with EMG capabilities are used, then convenience is improved, but measurement precision and depth of analysis are insufficient
Solution Approach 1:
The system applies local quality by positioning specific EMG sensors over the core and lower back muscle regions where they are most needed. Rather than using generic sensors placed arbitrarily, the system strategically locates sensors to capture signals from specific muscle groups. This localized sensor placement, combined with region-specific signal processing, delivers targeted analysis for core and lower back muscles while maintaining the convenience of a wearable format.
