Remote Bucket Angle Display for In-Cab Loader Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work vehicles, such as loaders, face inefficiencies in determining the orientation of work implements like buckets relative to the vehicle frame, often requiring them to exit the vehicle to assess positions, which disrupts operation.
Innovation Solution
A system that remotely displays the angular position of a work implement on a portable device, using a sensor to transmit data wirelessly to the device, allowing operators to view the implement's position without leaving the cab, through calibration of predefined angular positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the operator exits the loader to observe the bucket position, then the operator can determine the orientation of the bucket relative to the frame, but the efficiency of the loader operation is reduced
Solution Approach 1:
The patent creates a visual copy of the bucket's angular position that can be viewed inside the cab. A sensor detects the actual bucket position and this information is displayed on a screen mounted in the operator's cab, allowing the operator to see a representation of the bucket orientation without physically exiting the vehicle to observe the actual position.
2Productivity
If the operator remains inside the loader cab, then the loader operation efficiency is maintained, but the operator cannot determine the orientation of the bucket relative to the frame
Solution Approach 1:
The patent introduces an intermediary system consisting of a sensor, processing unit, and display screen. The sensor acts as an intermediary that captures bucket position data, processes it through a control unit, and presents it to the operator via a visual display inside the cab, thereby bridging the gap between the operator's confined position and the need for position information.
3Ease of operation
If a remote display system is implemented, then the operator can view implement position inside the cab, but the system complexity increases
Solution Approach 1:
The patent utilizes existing multi-functional components within the loader's electrical system. The display screen and processing unit are integrated into the existing cab environment and electrical infrastructure, allowing the system to serve multiple purposes: displaying bucket position, providing operational feedback, and integrating with the loader's existing control architecture, thereby reducing the net increase in complexity.

AI summary
A remote angular position display system and method are disclosed. The angular position of a work implement of a work vehicle is displayed (e.g., textually, numerically or graphically) on a display associated with a portable device. The angular position is observed by a sensor coupled to the work implement or the work vehicle. The method includes receiving, by a processor of the portable device, one or more signals from the sensor indicative of an angular position value, and determining, by the processor, a condition associated with the work implement based on the angular position. The method includes outputting, by the processor, an interface for rendering on the display associated with the portable device that indicates the angular position and the determined condition associated with the work implement of the work vehicle.
