Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired load management systems are used, then system reliability is improved, but installation complexity and time increase significantly
Solution Approach 1:
The patent replaces wired mechanical connections with wireless communication technology. The scale system uses wireless transmitters to send load data to receivers, eliminating the need for physical wiring between components. This substitution maintains data transmission reliability while dramatically reducing installation complexity and time.
Solution Approach 2:
The patent extracts the communication function from the mechanical structure by separating the wireless transmitter from the scale components. The transmitter can be independently installed and configured without modifying the structural integrity of the scale, allowing flexible installation while maintaining system reliability.
2Measurement precision
If wired load management systems are used, then data accuracy is improved, but installation time increases
Solution Approach 1:
The patent substitutes wireless communication for wired connections, maintaining data accuracy through digital signal transmission while reducing installation time by eliminating extensive wiring requirements. The wireless transmitter can be quickly installed and configured without time-consuming electrical connections.
Solution Approach 2:
The wireless transmitter is designed to be pre-configured and easily installed on existing scale components. The system allows for preliminary setup of communication parameters before actual use, reducing on-site installation time while ensuring accurate data transmission from the outset.
3Loss of time
If wireless scale systems are used, then installation time is reduced, but measurement precision may deteriorate
Solution Approach 1:
The patent employs wireless communication technology that maintains measurement precision by using digital signal processing and error correction protocols. The wireless transmission of load data preserves accuracy while eliminating the time-consuming wiring process, as the digital signals can be transmitted reliably over wireless channels with appropriate shielding and protocol implementation.
4Loss of information
If load management systems provide comprehensive data, then decision-making quality is improved, but system complexity increases
Solution Approach 1:
The wireless transmitter is designed as a multi-functional device that simultaneously performs weight measurement, data processing, wireless communication, and data logging. This universal design provides comprehensive load data for decision-making while consolidating multiple functions into a single component, thereby reducing overall system complexity rather than increasing it.
Solution Approach 2:
The patent merges the functions of the scale sensor, data processor, wireless transmitter, and memory storage into an integrated system. By combining these previously separate components into a unified wireless scale system, the patent provides comprehensive data for informed decision-making while reducing system complexity through functional integration.
