Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feed gripping devices are inefficient and inaccurate in providing the correct amount of feed, leading to issues like rotting or insufficient feeding, due to reliance on static height measurements and failure to account for changing feed density and shape.
Innovation Solution
A feed gripping device with a grab bucket carrier and grab bucket that can move horizontally and vertically, equipped with sensors to measure parameters like height and weight, and a control unit that adjusts the grabbing depth based on real-time measurements to ensure accurate feeding, dynamically adapting to changes in feed density and shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static height measurements are used to control grabbing depth, then the device structure is simple, but the feeding accuracy deteriorates due to changing feed density and shape
Solution Approach 1:
The patent implements dynamic control by continuously measuring the actual weight of grabbed feed and adjusting the grabbing depth in real-time based on feedback from weight sensors. This transforms the static height-based control into a dynamic system that adapts to changing feed density and shape, resolving the contradiction between simple structure and accurate feeding.
Solution Approach 2:
The patent introduces a feedback mechanism where weight sensors measure the actual amount of grabbed feed, and the control unit uses this information to adjust the grabbing depth for subsequent operations. This closed-loop feedback system improves feeding accuracy without requiring complex mechanical structures, as the adjustment is achieved through intelligent control based on measured parameters.
2Manufacturing precision
If grabbing depth is adjusted dynamically based on real-time measurements, then feeding accuracy is improved, but device complexity increases due to additional sensors and control mechanisms
Solution Approach 1:
The patent replaces complex mechanical adjustment mechanisms with electronic sensing and control systems. Instead of using multiple adjustable mechanical components to achieve accurate feeding, the system uses weight sensors and a control unit that calculates and adjusts grabbing depth electronically, reducing mechanical complexity while improving precision.
Solution Approach 2:
The patent changes the control parameter from static height measurements to dynamic weight measurements. By measuring the actual weight of grabbed feed and using this parameter to adjust subsequent grabbing operations, the system achieves high feeding accuracy through parameter optimization rather than mechanical complexity.
3Device complexity
If the device uses predetermined information about material distribution, then the control system is simple, but the reliability deteriorates when feed density and shape change
Solution Approach 1:
The patent implements a feedback mechanism where the actual weight of grabbed feed is measured and used to update the control system's information about feed distribution. This allows the system to adapt to changing feed density and shape, maintaining reliability without requiring a permanently complex control structure, as the complexity is activated only when changes are detected.
Solution Approach 2:
The system performs self-updating by automatically adjusting its internal model of feed distribution based on actual measurements from weight sensors. This self-service capability allows the device to maintain reliability under changing conditions without external intervention or permanently complex control mechanisms, as it adapts autonomously based on measured data.
4Manufacturing precision
If weight measurement and continuous updating are implemented, then feeding precision is improved, but energy consumption increases due to continuous sensing and control operations
Solution Approach 1:
The patent implements periodic measurement and updating rather than continuous operation. The weight sensors and control unit operate at specific intervals during the feeding process, measuring grabbed feed weight and updating the grabbing depth parameters periodically. This reduces energy consumption compared to continuous sensing while maintaining sufficient feeding precision through strategic measurement timing.
