Rotary High-Pressure Tool Switching With Integrated Valve Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switching apparatuses for high pressure tools require separate valve devices for each tool, leading to a complex structure, increased manufacturing costs, and reduced reliability due to additional space requirements and assembly complexities.
Innovation Solution
A compact switching apparatus with a rotary body that integrates the supply channel and valve device, allowing for selective unblocking and blocking of the cleaning liquid supply, eliminating the need for separate valve devices and simplifying the construction by positioning the valve device on the rotary body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate valve devices are provided for each high pressure tool, then each tool can be controlled independently, but the device complexity increases and manufacturing costs rise
Solution Approach 1:
The patent combines multiple valve devices into a single integrated valve unit that controls the supply channel serving multiple high pressure tools. This merging approach reduces the total number of valve devices from multiple separate units to one unified unit, thereby simplifying the overall structure while maintaining the capability to independently control each tool through the integrated valve's positioning mechanism
Solution Approach 2:
The integrated valve device serves multiple functions by controlling the supply channel that distributes cleaning liquid to multiple different high pressure tools. This single valve unit replaces what would traditionally require multiple separate valve devices, achieving multi-functionality while reducing device complexity
2Adaptability or versatility
If separate valve devices are provided for each high pressure tool, then each tool can be controlled independently, but manufacturing costs and assembly complexity increase
Solution Approach 1:
The patent merges multiple separate valve devices into one integrated valve unit that serves all high pressure tools through a common supply channel. This consolidation reduces the number of components that need to be manufactured and assembled, thereby simplifying the manufacturing process and reducing assembly complexity while preserving independent tool control capability
3Adaptability or versatility
If separate valve devices are provided for each high pressure tool, then each tool can be controlled independently, but the reliability decreases due to additional components
Solution Approach 1:
The patent combines multiple valve devices into a single integrated unit, reducing the total number of valve components in the system. Fewer separate components mean fewer potential failure points, thereby improving system reliability while the integrated design maintains the ability to independently control each high pressure tool through the unified valve's positioning mechanism
4Adaptability or versatility
If separate valve devices are provided for each high pressure tool, then each tool can be controlled independently, but the space requirements and assembly complexities increase
Solution Approach 1:
The patent merges multiple separate valve devices into one compact integrated valve unit that controls the supply channel for multiple high pressure tools. This consolidation significantly reduces the space required compared to having multiple separate valve devices distributed throughout the system, while maintaining independent tool control through the integrated valve's positioning capability
