Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual recording methods are used for tracking exercise, then device complexity is reduced, but measurement precision and reliability of exercise data are deteriorated due to human error and forgetfulness
Solution Approach 1:
The exercise measuring device automatically detects and records exercise data without requiring manual intervention. The tag attached to the weight portion and reader in the measuring device work together to automatically identify weight, count repetitions, and track exercise metrics, eliminating the need for users to manually record data and ensuring accurate tracking.
Solution Approach 2:
The patent replaces manual recording mechanisms with automated detection systems. Instead of relying on human memory and manual writing, the system uses a tag-reader interface to automatically detect weight portions and exercise parameters, converting a manual mechanical process into an automated electronic detection and recording system.
2Productivity
If automated measurement devices are added to track exercise, then measurement precision and exercise management are improved, but device complexity and cost are worsened
Solution Approach 1:
The exercise measuring device is divided into separate functional components: a tag attached to the weight portion containing exercise information, and a reader in the measuring device that detects the tag. This segmentation allows each component to be simple and inexpensive individually, while providing sophisticated automated measurement capabilities when combined.
Solution Approach 2:
The measuring device integrates multiple functions into a single unit: weight detection through tag reading, repetition counting through sensors, and data recording. This multi-functionality improves exercise management efficiency without requiring multiple separate devices, thereby limiting the increase in overall system complexity.
3Loss of information
If detailed exercise tracking is implemented, then loss of information is reduced, but device complexity and data processing requirements are worsened
Solution Approach 1:
Exercise information is pre-encoded into tags attached to weight portions before use. The tag contains predetermined information about weight and exercise parameters, which are automatically read by the measuring device during exercise. This preliminary encoding of information eliminates the need for complex real-time data processing during exercise execution.
