Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If personal health monitoring devices are strapped to the wrist or chest for smaller form factor, then portability and wearability are improved, but the device shifts position during strenuous athletic activities causing inaccurate data collection
Solution Approach 1:
The patent employs a flexible adhesive patch that conforms to the contours of the user's body (chest, abdomen, or back). This flexible film structure maintains intimate contact with the skin surface during movement, preventing device shifting while preserving the compact form factor. The adhesive layer acts as a flexible mounting substrate that secures the electronics without rigid constraints.
2Ease of operation
If traditional acrylate-based adhesives are used for attaching the wearable device, then ease of attachment is improved, but harmful effects on the user's skin occur
Solution Approach 1:
The patent fundamentally changes the chemical composition parameters of the adhesive material. Instead of using traditional acrylate-based adhesives, the invention employs a biocompatible adhesive formulation that eliminates harmful chemicals while maintaining effective bonding properties. This parameter change in material composition resolves the contradiction between ease of attachment and skin safety.
3Adaptability or versatility
If a single wearable device is used to monitor multiple activities, then device versatility is improved, but comprehensive workload details including core body temperature prediction are not provided
Solution Approach 1:
The patent implements a multi-functional sensor array within a single wearable device that simultaneously monitors multiple physiological parameters (heart rate, temperature, acceleration, ECG) and biomechanical metrics. This universal monitoring capability across diverse activities generates comprehensive workload data, including the ability to predict core body temperature, thereby resolving the information loss contradiction.
4Duration of action of moving object
If the wearable device is designed for continuous monitoring during strenuous activities, then monitoring duration is improved, but device shifting occurs leading to unreliable data
Solution Approach 1:
The patent employs a pre-applied adhesive patch that is attached to the skin before the monitoring session begins. This preliminary attachment action creates a secure baseline position that prevents device shifting throughout the entire duration of strenuous activities. The adhesive is applied in advance to ensure stable contact, thereby maintaining data reliability over extended monitoring periods.
