Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a digital interface with local control element is integrated into the implement, then load weight determination accuracy and anti-interference capability are improved, but device complexity increases
Solution Approach 1:
The patent replaces analogue signal transmission with digital interface communication. The local control element processes sensor signals digitally and transmits data through a digital interface, substituting the traditional mechanical/hydraulic signal transmission system with an electronic digital system, thereby improving measurement precision and anti-interference capability
Solution Approach 2:
The patent introduces a local control element as an intermediary between the sensor and the work vehicle control system. This intermediate device processes sensor signals locally, performs load weight calculations, and communicates through a digital interface, thereby improving measurement accuracy while isolating the complexity from the work vehicle side
2Measurement precision
If vehicle modifications are required for load weight determination, then measurement capability is improved, but ease of operation and adaptability deteriorate
Solution Approach 1:
The patent designs the implement with a standardized digital interface and local control element that can be integrated into different work vehicle systems without modifying the vehicle itself. The implement becomes a self-contained unit with universal compatibility, allowing the same implement to be used across multiple vehicle platforms while maintaining load weight measurement capability
3Device complexity
If analogue signal transmission is used between implement and vehicle, then device complexity is reduced, but reliability deteriorates due to signal interference
Solution Approach 1:
The patent substitutes analogue signal transmission with digital interface communication. Digital signals are more resistant to interference and noise compared to analogue signals, thereby improving reliability and signal transmission stability while maintaining acceptable system complexity through integrated control electronics
