Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerial cable transportation systems face challenges in supporting hauling cables at intermediate structures during transverse winds, leading to cable deviation and potential mechanical stress due to the inability of standard rollers to absorb lateral strains effectively.
Innovation Solution
A roller battery device with slidable entry and exit rollers, equipped with rocker arms and sensors to adjust positions and detect deviations, allowing for adaptive support of the hauling cable and prevention of excessive strain transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard fixed rollers are used to support the hauling cable, then the structure is simple and stable, but the cable deviates from its theoretical position under transverse wind loads
Solution Approach 1:
The patent applies the dynamics principle by making the entry and exit rollers slidable along the longitudinal axis of the roller battery device. This allows the rollers to dynamically adjust their positions in response to transverse wind forces acting on the cable, enabling the system to adapt to varying load conditions while maintaining cable support stability.
Solution Approach 2:
The patent implements parameter changes by allowing the rollers to change their positional parameters along the longitudinal axis. The slidable mechanism enables the rollers to move to different positions based on the magnitude and direction of transverse forces, thereby optimizing the support configuration under different operating conditions.
2Device complexity
If fixed rollers are used, then the device complexity is low, but excessive transverse strains are transmitted to the intermediate structure
Solution Approach 1:
The slidable roller mechanism allows the support structure to dynamically absorb transverse strains by permitting controlled movement of the rollers along the longitudinal axis. This dynamic adjustment reduces the transmission of excessive transverse forces to the intermediate structure while maintaining structural integrity.
3Ease of operation
If standard rollers are used, then the system is simple to operate, but cable 'fleeting' (lateral displacement outside roller) may occur under strong wind
Solution Approach 1:
The patent incorporates sensors that detect the position of the hauling cable and provide feedback to the control system. Based on this feedback, the control system actuates the slidable rollers to adjust their positions, ensuring the cable remains properly supported and preventing lateral displacement or 'fleeting' even under strong wind conditions.
Solution Approach 2:
The patent replaces the purely passive mechanical roller support system with an active controlled system that uses sensors and actuators. This substitution enables real-time monitoring and adjustment of roller positions, significantly improving cable support reliability while preventing hazardous conditions.
4Reliability
If slidable rollers with sensors and actuators are implemented, then cable position stability is improved, but the device complexity increases
Solution Approach 1:
The controlled roller battery device uses sensors to monitor cable position and provides feedback to a control system that adjusts roller positions accordingly. This feedback mechanism ensures high cable position stability by continuously adapting the support configuration to match actual operating conditions.
Solution Approach 2:
The patent replaces the simple passive mechanical roller system with an active controlled system incorporating sensors, actuators, and control logic. This substitution significantly enhances cable support reliability and prevents hazardous conditions, justifying the increased device complexity through improved performance and safety.
