Solution Overview
Problem
Existing nondestructive test methods for wire ropes lack efficient data recording capabilities, particularly in remote or inaccessible areas, as they often require manual operation and are cumbersome due to the weight and complexity of data recording equipment.
Innovation Solution
A remote data recorder (RDR) system is integrated with a wire rope sensor head, featuring a unitized signal processor, multi-channel FM tape recorder, and power supply, allowing for automated data collection and recording of loss of metallic area and local fault signals, with features like manual or auto-start functionality and signal conditioning to enhance data accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual data recording methods are used for wire rope testing, then equipment simplicity is maintained, but data recording efficiency and automation capability deteriorate
Solution Approach 1:
The patent combines the data recording functionality with the sensor head by integrating a microcontroller, memory storage, and processing circuits directly into the sensor assembly. This merging allows automated data collection and storage during wire rope testing without requiring separate external recording equipment, thereby improving productivity while controlling device complexity through functional integration.
Solution Approach 2:
The sensor head is designed with self-contained data recording capabilities including onboard memory, processing units, and automated signal analysis functions. The system performs self-service by automatically capturing, storing, and analyzing test data during operation, eliminating the need for manual operation and external recording equipment, thus enhancing productivity without proportionally increasing overall system complexity.
2Productivity
If automated data recording system is integrated with sensor head, then data recording efficiency is improved, but sensor head weight increases
Solution Approach 1:
The patent implements local quality by strategically placing only the essential automated recording components (microcontroller, minimal memory storage, and processing circuits) within the sensor head, while keeping the overall system design lightweight. The sensor head maintains its primary sensing function with added localized intelligence for data management, achieving automated data collection without excessive weight gain.
Solution Approach 2:
The system employs parameter changes by using compact, low-power electronic components with optimized memory capacity that match the specific data requirements of wire rope testing. The microcontroller and storage elements are selected to provide sufficient automated recording capability while maintaining minimal weight, balancing productivity improvement with weight constraints through careful parameter selection.
3Adaptability or versatility
If remote data recording capability is added, then testing in remote areas becomes feasible, but device complexity increases
Solution Approach 1:
The sensor head is designed with universal functionality by integrating multiple capabilities into a single device: sensing, data acquisition, processing, storage, and remote transmission. The microcontroller-based system can operate autonomously in remote areas without external equipment while also providing processed data output, making the system adaptable to various testing environments without requiring separate specialized equipment for each function.
Solution Approach 2:
The patent uses the microcontroller and onboard memory as intermediaries between the sensor elements and the external world. These components buffer and process data locally, allowing the system to function independently in remote areas and then transfer data when connectivity is available, reducing the need for complex real-time transmission systems while maintaining remote testing capability.
