Oblique Toothing Feed Unit Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feed units with obliquely aligned toothing parts lack efficient mechanisms for alternative filling and emptying of working spaces without the need for additional valves or control elements, leading to suboptimal flow control and pulsation issues during emptying.
Innovation Solution
The feed unit incorporates recesses and connecting channels on the toothing parts, forming flow connections that automatically open during filling and close during emptying, with control grooves and channels that facilitate flow without additional valves, and in one embodiment, uses valve elements to control flow direction and reduce pulsation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional valves or control elements are used to control filling and emptying of working spaces, then flow control precision is improved, but device complexity increases
Solution Approach 1:
The recesses in the first and second toothing parts automatically control the filling and emptying of working spaces through their own geometric configuration and relative motion, without requiring external valves or control elements. The system serves itself by using the interaction between the toothing parts' recesses to regulate fluid flow.
Solution Approach 2:
The patent removes additional valves and control elements from the system, retaining only the essential toothing parts with integrated recesses. This extraction of unnecessary components simplifies the device while maintaining flow control functionality through the geometric design of the toothing parts themselves.
2Reliability
If traditional valve mechanisms are used for emptying working spaces, then flow control is achieved, but pulsation during emptying increases
Solution Approach 1:
The recesses in the toothing parts create periodic opening and closing of flow paths during the rotational motion, enabling controlled filling and emptying phases. This periodic geometric interaction provides smooth flow control without the harmful pulsations associated with traditional valve mechanisms.
3Device complexity
If simple recess configurations are used in toothing parts, then device complexity is reduced, but flow connection effectiveness decreases
Solution Approach 1:
The recesses are strategically positioned and dimensioned in specific locations on the toothing parts to optimize flow connection effectiveness. The local geometric configuration of each recess is tailored to its specific function in the filling or emptying phase, achieving high productivity without increasing overall device complexity.
