Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If integrated monitoring systems are built into free weights and exercise equipment, then measurement precision and reliability are improved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The system divides the monitoring function into separate components: attachment devices with sensors are detached from the main exercise equipment. These modular attachments can be connected to different pieces of equipment as needed, avoiding the complexity of integrating monitoring systems into each individual piece of equipment while maintaining measurement precision.
Solution Approach 2:
The patent introduces an intermediary computing device that acts as a bridge between the simple attachment devices and the user's smartphone or tablet. This intermediary handles data processing and communication, allowing the attachment devices to remain simple while achieving reliable and precise fitness tracking through the coordinated system.
2Adaptability or versatility
If wearable devices are used to track motion and vitals, then adaptability and ease of operation are improved, but measurement precision for strength training metrics deteriorates
Solution Approach 1:
The attachment devices are designed with specialized sensors positioned at specific locations on the exercise equipment where force and motion data can be most accurately measured. This localized measurement approach provides precise strength training metrics while maintaining the adaptability of wearable technology through various attachment options for different exercises.
3Measurement precision
If commercial gym machines with integrated monitoring are used, then measurement precision is improved, but cost and device complexity increase
Solution Approach 1:
The monitoring functionality is extracted from expensive commercial gym machines and placed into inexpensive attachment devices that can be used with any equipment. This extraction allows precise fitness tracking without requiring costly specialized equipment, making the system affordable for home use while maintaining measurement accuracy.
4Measurement precision
If force sensors are integrated into attachment devices, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The attachment devices are designed to perform multiple functions: they can measure force when equipped with sensors, or they can work with smartphone sensors and user input when sensors are not present. This multi-functionality allows the same basic attachment design to provide accurate measurements through different methods, reducing device complexity while maintaining measurement precision across various configurations.
