Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forklift user interfaces require excessive labor and time for adjustments, leading to inefficiencies and operator fatigue due to poorly positioned controls, reducing overall productivity.
Innovation Solution
A multi-function user interface with a manipulator assembly and grip that detects user presence, allowing control of multiple forklift functions through a single input device, including a joystick and capacitive sensor, with integrated storage and USB charging, reducing the need for manual adjustments and minimizing fatigue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate controls are provided for different forklift functions, then each function can be controlled independently, but the number of controls increases and requires more operator movement and time
Solution Approach 1:
The manipulator assembly is designed as a universal control device that can perform multiple functions. A single manipulator assembly with grip can control mast tilt, fork position, lift platform movement, and other implement functions through different input devices (joystick, buttons, rockers) integrated into one assembly, eliminating the need for separate controls for each function.
2Ease of operation
If traditional user interfaces are positioned for easy access, then controls are reachable, but they require excessive operator movement and cause fatigue during continuous operation
Solution Approach 1:
Multiple control functions are merged into a single manipulator assembly that is positioned within easy reach of the operator. The assembly integrates multiple input devices (joystick, buttons, rockers) into one compact unit that can be operated from a single seated position, eliminating the need for the operator to move between separate controls located in different positions throughout the cab.
3Manufacturing precision
If manual adjustments are required for mast and forks, then precise control is possible, but excessive time is consumed reducing overall operational capacity
Solution Approach 1:
Manual mechanical adjustments are replaced with an electronically controlled manipulator assembly. The input devices (joystick, buttons, rockers) send electronic signals to control the implement functions, providing precise control of mast tilt and fork position while eliminating the time-consuming manual adjustment process. The system uses sensors and electronic actuators to achieve precise positioning without manual intervention.
