Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If non-premium golf balls (range balls) are used for practice, then durability and cost-effectiveness are improved, but flight distance and performance accuracy deteriorate due to flight restrictions
Solution Approach 1:
The system changes the parameter of flight distance through mathematical transformation. It detects the actual flight distance of the range ball and applies a transformation function to calculate what the distance would be with a premium ball, effectively converting the restricted flight parameter to an unrestricted equivalent
Solution Approach 2:
A transforming module acts as an intermediary between the actual flight trace and the displayed feedback. This module processes the captured trace data and converts it into corrected trace information that reflects premium ball performance, mediating between the physical reality of range ball flight and the desired feedback representation
2Loss of information
If non-premium golf balls are used, then cost is reduced, but measurement precision of performance feedback deteriorates
Solution Approach 1:
The system transforms the measured parameters by applying correction functions that adjust flight distance, air time, and other performance metrics from range ball values to equivalent premium ball values, restoring measurement precision without increasing cost
Solution Approach 2:
The system implements feedback by providing corrected performance information to the golfer. The transforming module generates accurate feedback data that reflects what the performance would be with a premium ball, allowing the golfer to receive precise performance assessment while using cheaper range balls
3Device complexity
If linear scaling is applied to correct flight restriction, then simplicity is maintained, but measurement precision deteriorates due to inability to account for non-linear flight characteristics
Solution Approach 1:
The system transitions from static linear scaling to dynamic transformation functions that adapt based on shot parameters. The transforming module selects and applies different transformation functions based on detected conditions, allowing precise correction of non-linear flight characteristics while maintaining manageable system complexity through automated selection
Solution Approach 2:
The system changes the transformation approach from fixed linear scaling to variable transformation functions that adjust correction factors based on shot distance, ball type, and other parameters. This enables accurate correction of non-linear flight behavior while the system manages complexity by automatically selecting appropriate transformation functions
