Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic systems in forestry and agriculture machines suffer from non-intuitive operation of levers, leading to dangerous situations and prolonged loading times due to limited lever functionality and the inability to operate multiple valves simultaneously.
Innovation Solution
A system comprising a sensor unit on the user's body, an evaluation unit, and a control unit that processes sensor data to control hydraulic valves intuitively and simultaneously, allowing safe and efficient operation of multiple valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple levers are used to control hydraulic valves, then the device complexity is reduced, but the ease of operation deteriorates due to non-intuitive operation and limited settings
Solution Approach 1:
The patent replaces traditional mechanical lever controls with a sensor unit that detects body movements and gestures. The sensor unit captures movement data from the user's body and translates it into control signals for hydraulic valves, eliminating the need for complex mechanical lever systems while providing intuitive control that follows natural human motion patterns.
Solution Approach 2:
The patent introduces an evaluation unit as an intermediary between the sensor unit and the hydraulic valves. This evaluation unit processes the raw movement data from the sensor unit and converts it into appropriate control signals for the hydraulic system, enabling natural body movements to be translated into precise valve control without requiring the user to understand complex mechanical control mechanisms.
2Ease of operation
If multiple levers are provided to control multiple hydraulic valves, then the ease of operation improves, but the device complexity increases and the ability to operate multiple valves simultaneously is limited by human hand capacity
Solution Approach 1:
The sensor unit serves as a universal control interface that can detect and translate multiple different types of body movements and gestures into control signals for multiple hydraulic valves. A single sensor unit replaces multiple specialized levers, enabling the user to control multiple valves simultaneously through natural body movements without increasing physical control device complexity.
Solution Approach 2:
The patent replaces the mechanical lever system with a sensor-based detection system that captures body movements. This substitution allows multiple hydraulic valves to be controlled simultaneously through a single sensor unit that can process multiple movement inputs, overcoming the limitation of human hand capacity to operate only two levers at once.
3Productivity
If traditional lever controls are used, then the device complexity remains low, but the productivity deteriorates due to prolonged loading times caused by limited lever functionality
Solution Approach 1:
The patent replaces traditional mechanical lever controls with a sensor unit that detects body movements and translates them into control signals. This substitution enables faster and more intuitive control of hydraulic valves, reducing loading times by allowing users to operate multiple valves simultaneously through natural body movements rather than being limited by sequential lever operation.
Solution Approach 2:
The sensor unit continuously monitors body movements and is ready to translate them into control signals immediately, eliminating the delay associated with manual lever manipulation. The system is prepared to respond to user intentions as they naturally occur, reducing the time required for loading operations by eliminating the need to physically locate and manipulate multiple levers.
