Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If survey-grade GPS trackers with ground planes are used, then measurement precision is improved, but weight and device complexity increase
Solution Approach 1:
The invention extracts and removes the ground plane component from the GPS antenna system. By eliminating this heavy metallic structure, the tracker weight is significantly reduced while maintaining survey-grade accuracy through alternative signal processing methods and antenna designs that don't require traditional ground planes.
Solution Approach 2:
The invention changes the operational parameters of the GPS system by using multi-frequency signals (L1, L2, L5) and advanced signal processing algorithms. This allows the system to achieve high precision without relying on the physical ground plane structure, thereby reducing weight while maintaining measurement accuracy.
2Measurement precision
If survey-grade GPS trackers with ground planes are used, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The invention removes the complex ground plane structure from the GPS antenna design. This simplification eliminates the need for large metallic structures and complex mounting requirements, reducing overall device complexity while maintaining high precision through software-based corrections and multi-frequency signal processing.
Solution Approach 2:
The invention replaces the mechanical ground plane structure with electronic and software-based solutions. Advanced signal processing algorithms and multi-frequency reception replace the physical ground plane's function of improving signal accuracy, thereby reducing mechanical complexity while maintaining measurement precision.
3Device complexity
If recreational or map-grade GPS receivers are used, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The invention changes the signal processing parameters by utilizing multiple GPS frequencies (L1, L2, L5) and advanced correction algorithms. This allows the system to achieve survey-grade precision without the complex hardware requirements of traditional survey-grade receivers, effectively decoupling precision from hardware complexity.
Solution Approach 2:
The invention replaces hardware-based precision mechanisms with software-based signal processing and multi-frequency analysis. This substitution allows the system to achieve high measurement precision through computational methods rather than complex mechanical or electrical hardware structures.
4Measurement precision
If GPS trackers are attached to horses for racing, then location tracking is enabled, but weight impact on horse performance increases
Solution Approach 1:
The invention extracts and removes the heavy ground plane component from the GPS tracker, significantly reducing the weight that must be carried by the horse. This weight reduction is achieved without compromising the survey-grade measurement precision needed for accurate race position data and performance analysis.
Solution Approach 2:
The invention changes the technical parameters of the GPS system to achieve high precision through multi-frequency signal processing and advanced algorithms rather than through heavy hardware components. This parameter change enables lightweight tracker design that minimizes impact on horse performance while maintaining the measurement precision required for racing applications.
