Problem
Conventional proportional valve drivers in fluid power systems are difficult to access and adjust due to their placement and harsh environmental conditions, requiring physical adjustments or communication cables, which can be unsafe and inconvenient.
Innovation Solution
A wireless valve control system that includes a proportional valve driver with a wireless transceiver, a proportional translation unit, and a parameter unit, allowing for remote control and parameter adjustments via a user controller device through a wireless network, enabling secure and convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proportional valve drivers are placed near or on-board fluid control valves, then control performance is maintained, but physical access becomes difficult and unsafe
Solution Approach 1:
The patent replaces the mechanical/physical adjustment system with a wireless communication system. The proportional valve driver includes a wireless transceiver that communicates with remote devices, allowing parameter adjustments to be made wirelessly without physical access to the valve driver location. This substitution resolves the contradiction by maintaining control performance while eliminating the need for physical access.
2Ease of repair
If physical adjustment or cable connection is required, then parameter changes can be made, but safety risks increase in harsh environments
Solution Approach 1:
The patent replaces physical adjustment mechanisms and cable connections with wireless communication technology. The wireless transceiver enables parameter changes to be transmitted remotely through wireless signals, eliminating the need for personnel to physically access harsh environments or handle cables in dangerous conditions. This maintains ease of parameter adjustment while removing safety risks associated with physical access.
3Ease of operation
If wireless transceiver is added to proportional valve driver, then remote access is enabled, but device complexity increases
Solution Approach 1:
The wireless transceiver component serves multiple functions: it enables remote parameter adjustment, provides system status monitoring, and facilitates communication between the proportional valve driver and external devices. By integrating this multi-functional component, the patent achieves remote access capability while the transceiver's versatility helps justify the added complexity through its multiple uses within the system.
