Joystick Grip Integrated Display for Heavy Machinery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operating heavy machinery using joysticks is challenging due to the need for simultaneous focus on the joystick and actuating member, especially during movement, and determining the level position of actuating members like buckets is difficult visually.
Innovation Solution
A joystick with a pivotably connected grip assembly and base assembly, featuring an integrated display, such as an LCD, that provides user information like joystick position, fault messages, and machinery parameters, allowing users to operate the machinery more effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a traditional joystick without display is used, then the device complexity is low, but the user cannot obtain real-time information about actuating member position and machinery parameters
Solution Approach 1:
The patent combines the display device with the joystick grip assembly into an integrated unit. The display is mounted on the grip assembly, merging the information display function with the control operation function, allowing users to view machinery parameters and actuating member positions directly at the control location without adding separate external displays.
Solution Approach 2:
The joystick grip assembly serves multiple functions: it provides the mechanical control function for operating actuating members, and simultaneously serves as a mounting platform for the display device to present information to the user. This multi-functionality reduces the need for separate components and minimizes overall system complexity.
2Ease of operation
If the user focuses on the joystick to operate actuating members, then the control precision is improved, but the user cannot monitor the machinery movement and actuating member position simultaneously
Solution Approach 1:
The display device provides real-time feedback to the user about actuating member positions, bucket level positions, and machinery parameters. This feedback loop allows users to monitor system state continuously while operating the joystick, eliminating the need to shift attention between the joystick and external monitors or visual inspection of the machinery.
Solution Approach 2:
The display acts as an intermediary between the machinery system and the user, translating complex machinery states and actuating member positions into visible information that the user can quickly interpret. This intermediary provides the user with situational awareness without requiring direct visual contact with the machinery components.
3Measurement precision
If visual monitoring of actuating member position is used, then the user can determine level position, but this is difficult when the machinery is moving and the user must also control the joystick
Solution Approach 1:
The display provides continuous feedback on actuating member positions and level detection information, allowing users to determine when the bucket or other components are at the desired level without visually monitoring the moving machinery. This feedback enables precise level detection while maintaining focus on joystick operation.

AI summary
A joystick for operating heavy machinery. The joystick has a base assembly and a grip assembly wherein a display is integrated into the first end of the grip assembly and the second end is pivotably mounted within the base assembly. Movement of the grip assembly relative to the base assembly moves an actuating assembly of the heavy machinery wherein the display is able to provide useful information to the user during operation.
