Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual inspection of disc blades in tillage implements is imprecise and time-consuming due to wear and deformation over time.
Innovation Solution
A disc blade deformation detection system using emitters and sensors to determine the wear status of disc blades by directing a beam across the blades and detecting its obstruction, with a controller analyzing the sensor signals to assess wear and deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection of disc blades is performed, then the system is simple and easy to operate, but the measurement precision and time consumption are poor
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated optical detection system. An emitter directs a beam across the disc blades, and a sensor receives the beam to detect wear status automatically, eliminating the need for manual measurement tools and human inspection while providing precise, quantitative wear data.
Solution Approach 2:
The disc blade wear detection system performs self-inspection automatically during or between operational periods. The controller continuously or periodically monitors blade wear through the emitter-sensor system without requiring operator intervention, enabling the system to self-diagnose and report wear status.
2Productivity
If manual inspection of multiple disc blades is performed, then the device complexity is low, but the productivity and inspection efficiency are reduced
Solution Approach 1:
The detection system is segmented into distinct functional modules: an emitter module that directs the beam, a sensor module that detects the beam, and a controller that processes signals. This modular segmentation allows each component to perform its specific function efficiently while keeping individual component complexity low, even though the overall system provides high-productivity multi-blade inspection.
3Measurement precision
If automated beam-based detection system is implemented, then measurement precision and productivity are improved, but device complexity increases
Solution Approach 1:
The patent introduces a controller as an intermediary between the simple emitter-sensor optical system and the complex task of wear analysis. The controller receives signals from the sensor, processes the data to determine wear status, and can trigger alerts or logging. This intermediary handles the computational complexity, allowing the physical detection components to remain relatively simple while achieving high measurement precision.

AI summary
A control system for a tillage implement includes an emitter configured to direct a beam across a set of disc blades of the tillage implement. An axis of the beam is configured to intersect the set of disc blades at a first position radially offset from a rotational axis of the set of disc blades. The control system also includes a sensor configured to receive the beam associated with the emitter. The control system also includes a controller including a memory configured to store instructions and one or more processors. The controller is configured to receive a signal from the sensor indicative of detection of the beam. The controller is also configured to determine a wear status of the set of disc blades based on the signal.
