Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of effective communication between work machines and their associated attachments, leading to inefficiencies in operation and functionality, particularly in hydraulic systems, as operators rely on visual feedback and simple sensors without comprehensive data exchange.
Innovation Solution
Implementing an identification module with a transmitter in the attachment to transmit identification information to the work machine, allowing for the determination of preferred operating pressures and flow rates, and enabling automatic adjustments to travel speed or hydraulic fluid provision based on measured pressures and flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple sensors and visual feedback are used for monitoring hydraulic pressure, then device complexity is reduced, but measurement precision and operational efficiency deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where the work machine receives identification information from the attachment, determines preferred operating parameters, measures actual hydraulic pressure, and provides real-time feedback to the operator when pressure deviates from preferred levels. This continuous feedback loop enables precise monitoring and control without requiring complex sensor systems in the attachment itself.
Solution Approach 2:
The work machine acts as an intermediary that processes identification information from the attachment and provides centralized hydraulic pressure monitoring and control. Instead of placing complex sensing and control systems in each attachment, the work machine serves as a mediator that manages multiple attachments and their hydraulic parameters centrally.
2Device complexity
If visual feedback is used for operator control, then device complexity is minimized, but productivity and operational efficiency deteriorate due to reliance on manual monitoring
Solution Approach 1:
The system provides automated feedback to the operator about hydraulic pressure deviations from preferred operating parameters, enabling faster and more accurate adjustments without requiring constant visual monitoring. This feedback mechanism improves operational efficiency by alerting operators only when adjustments are needed.
Solution Approach 2:
The system enables the work machine to automatically determine preferred operating parameters based on identification information from the attachment, reducing the need for operator knowledge and manual adjustment. The machine essentially monitors and guides its own operation, improving productivity while keeping the control interface simple.
3Device complexity
If generic hydraulic pressure control is used without attachment-specific parameters, then adaptability deteriorates, but device complexity is reduced
Solution Approach 1:
The system performs preliminary action by receiving identification information from the attachment before hydraulic operation begins. The work machine uses this identification information to determine preferred operating parameters in advance, such as optimal hydraulic pressure levels specific to each attachment type, ensuring optimized performance from the start of operation.
Solution Approach 2:
The system dynamically adapts hydraulic pressure control parameters based on the specific attachment being used. Instead of fixed generic pressure settings, the work machine adjusts preferred operating parameters dynamically according to the identification information received from different attachments, enabling optimization for each specific attachment while using a single standardized control system.
