Front Loader Bucket Display for Vertical Position and Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work vehicles, such as tractors equipped with buckets, face challenges in easily checking the vertical position and angle of the bucket while operating the vehicle.
Innovation Solution
A work vehicle is equipped with a display that synchronizes with the movement of the bucket to show vertical position and angle information, allowing operators to set and monitor these parameters easily through an intuitive interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the operator checks the bucket position and angle by visually observing the bucket directly, then no additional equipment is needed, but the operator cannot easily monitor the vertical position and angle parameters while operating the vehicle
Solution Approach 1:
The patent creates a visual copy of the bucket's actual position and angle parameters through a display device. Sensors detect the real bucket parameters, and the display shows these parameters graphically with rulers and indicators, allowing the operator to monitor bucket position and angle without directly observing the physical bucket, thus solving the information loss problem while maintaining ease of operation
Solution Approach 2:
The patent introduces an intermediary system consisting of sensors, processing units, and display devices between the bucket and the operator. This intermediary system converts physical bucket parameters into visual information that can be easily monitored by the operator, resolving the contradiction between information availability and operational convenience
2Measurement precision
If the operator leaves the vehicle to check the bucket position, then accurate visual inspection is possible, but operational efficiency decreases due to time loss
Solution Approach 1:
The patent replaces the mechanical approach of the operator physically leaving the vehicle to inspect the bucket with an electronic information system. Sensors and display devices provide real-time visual feedback of bucket position and angle parameters, allowing the operator to maintain measurement precision while staying inside the vehicle, thus eliminating time loss and improving productivity
Solution Approach 2:
The patent implements a feedback system where sensors continuously monitor bucket parameters and provide real-time visual feedback through the display. This feedback loop allows the operator to accurately monitor bucket position and angle without leaving the vehicle, maintaining measurement precision while continuously working, thereby improving operational efficiency
3Ease of operation
If complex control systems are added to monitor bucket parameters, then operational control improves, but device complexity increases
Solution Approach 1:
The patent segments the monitoring system into distinct functional modules: sensors for detecting parameters, processing units for calculating positions and angles, and display devices for visual presentation. This segmentation allows each component to perform its specific function simply, reducing overall system complexity while improving ease of operation through specialized, focused components
