Solution Overview
Problem
Conventional hoist systems, such as those used in aerospace, cranes, and elevators, lack real-time information about weight and stress exerted on the hoist-rescue system during operations, necessitating improved sensor systems and data transmission methods.
Innovation Solution
A hoist system utilizing a single conductor for both power and data transmission between sensors and receiving modules, where sensors generate time-variant electrical charge densities and transmit them along this single conductor, allowing for robust data extraction without a second conductor, enabling monitoring of loads and stress on hoist components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional two-wire systems are used for sensor data transmission, then reliable data transmission is achieved, but system complexity and weight increase
Solution Approach 1:
The patent combines power transmission and data transmission functions into a single conductor, eliminating the need for separate wiring for each function. This merging approach reduces the number of conductors required while maintaining both power supply and communication capabilities, directly addressing the contradiction between reliability and complexity.
Solution Approach 2:
The single conductor serves multiple functions simultaneously: it provides power to the sensor, transmits data from the sensor, and can carry control signals. This multi-functionality eliminates the need for dedicated wiring for each function, reducing overall system complexity while maintaining reliable operation.
2Reliability
If conventional two-wire systems are used for sensor data transmission, then complete circuit connection is achieved, but weight and material usage increase
Solution Approach 1:
By merging power and data transmission into a single conductor, the patent reduces the total quantity of conductor material needed. Instead of requiring two separate wires for power and data, one conductor performs both functions, directly reducing material usage while maintaining circuit connection reliability through proper signal grounding and reference connections.
3Productivity
If real-time sensor monitoring is implemented, then health monitoring capability is improved, but data transmission reliability in harsh environments deteriorates
Solution Approach 1:
The patent replaces complex multi-conductor electrical signaling with a simplified single-conductor system that uses voltage-level modulation and reference grounding. This substitution of the transmission approach reduces susceptibility to electromagnetic interference and environmental factors, maintaining reliability while enabling real-time monitoring.

AI summary
A hoist system (100) includes a load attaching member (102) a single conductor (104) connecting the load attaching member to a hoist (106) for raising and lowering the load attaching member and single conductor. A sensor (108) is operatively connected to the load attaching member to sense a monitored parameter of the load attaching member. The sensor is electrically connected to a receiving module (110) of the hoist for single wired-transmission along the single conductor from the sensor to the receiving module.
