Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual manufacture of the scale is carried out taking into consideration the intended placement location, then measurement precision is improved, but manufacturing cost increases
Solution Approach 1:
The invention separates the scale into two parts: a universally manufacturable base unit and a location-specific correction factor. The correction factor (derived from GPS coordinates or manual input) is segmented as a separate data element that adapts the universal device to local gravity conditions, eliminating the need for individualized manufacturing while maintaining measurement precision.
Solution Approach 2:
The invention changes the gravity parameter dynamically based on location data. Instead of manufacturing different scales for different locations, the system modifies the measurement parameter (gravity value) according to GPS coordinates or manually entered location data, allowing a single universal design to adapt to various gravitational environments.
2Ease of manufacture
If the scale is manufactured according to a predetermined standard and adjusted at the actual location, then manufacturing cost is reduced, but operational delay and adjustment cost increase
Solution Approach 1:
The invention performs the adjustment action preliminarily through pre-stored correction factors associated with GPS coordinates or location codes. When the scale is first used at a location, the correction factor is automatically retrieved and applied, eliminating the need for time-consuming on-site calibration procedures and enabling immediate operational readiness.
3Measurement precision
If GPS receiver is equipped for automated location determination, then adjustment accuracy is improved, but manufacturing cost and system complexity increase
Solution Approach 1:
The invention introduces an intermediary layer (correction factor database) between the location determination system and the measurement system. Whether GPS or manual input is used, the location data is transformed into a correction factor that mediates the adaptation process, simplifying the overall system architecture and reducing complexity while maintaining accuracy.
4Ease of manufacture
If manual geographic position input is used, then manufacturing cost is reduced, but measurement reliability and security decrease due to input errors and manipulation
Solution Approach 1:
The invention implements feedback mechanisms through validation procedures that check the plausibility of entered location data and correction factors. The system provides feedback to the user about potential input errors and verifies that the correction factor corresponds to the entered location, preventing manipulation and ensuring measurement reliability while maintaining manual input simplicity.
