Variable Control Air Pick Device Radial Channel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressurized air pick devices with variable control require complex and expensive machining due to the need for small-diameter coaxial fluid-conveying channels to maintain the integrity of the body, which complicates the manufacturing process and increases costs.
Innovation Solution
A pressurized air pick device with a distribution portion housed in the cylinder, featuring two coaxial radial channels with a semi-cylindrical groove section for fluid conveyance, allowing for a larger flow rate without the need for extensive machining within the body, and a flexible supply tube connected to the fluid supply section for variable control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If small-diameter coaxial channels are formed in the distribution portion body, then the structural integrity of the body is maintained, but the machining complexity and cost increase significantly
Solution Approach 1:
The invention transitions from forming channels within the thickness of the distribution portion body (one-dimensional constraint) to forming channels in the cylindrical wall of the cylinder (utilizing the radial dimension). This dimensional shift allows channels to be formed outside the distribution portion body, eliminating the need for complex internal coaxial channel machining while maintaining structural integrity.
Solution Approach 2:
The invention extracts the fluid conveying function from the distribution portion body and relocates it to the cylinder wall. By taking out the channel formation requirement from the distribution portion body, the design eliminates the machining complexity associated with forming multiple small-diameter coaxial channels within the body thickness.
2Quantity of substance
If a large number of coaxial channels are formed in the distribution portion body, then the desired fluid flow rate is achieved, but the machining complexity and cost increase
Solution Approach 1:
The invention utilizes the radial dimension of the cylinder wall to form conveying channels, allowing channels to be positioned circumferentially around the distribution portion rather than being constrained to the body thickness. This enables achieving the required fluid flow rate without increasing the number of channels through complex internal machining.
Solution Approach 2:
The invention segments the fluid conveying function into multiple radial channels distributed around the cylinder perimeter. This segmentation allows the total fluid flow rate to be achieved through multiple parallel channels formed in the cylinder wall, simplifying the machining process compared to forming multiple coaxial channels through the distribution portion body.
3Stability of the object's composition
If coaxial channels are formed within the thickness of the distribution portion body, then the channels are contained within the body, but the channel cross-section is limited and flow rate is restricted
Solution Approach 1:
The invention extracts the conveying channels from the distribution portion body and relocates them to the cylinder wall. This extraction allows channels to have much larger cross-sectional areas since they are formed in the cylindrical wall rather than being constrained by the limited thickness of the distribution portion body, thereby significantly increasing fluid flow rate.
4Productivity
If multiple radial channels are formed in the distribution portion, then fluid distribution is improved, but the machining complexity increases
Solution Approach 1:
The invention merges the function of forming radial channels in the distribution portion with the formation of conveying channels in the cylinder wall. By combining these functions into a unified channel system where conveying channels in the cylinder wall connect to radial channels in the distribution portion, the design achieves improved fluid distribution while simplifying the overall machining process.
