Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art vibration pumps face challenges with large dimensions due to accessory components, difficulty in inspection and disassembly, and the need for additional parts for self-priming, which complicates manufacturing and increases costs.
Innovation Solution
A vibration pump design featuring a moving piston within a coil-generated magnetic field, with elastic means for noise reduction and self-priming, and a modular construction using a pump body divided into two parts for easier assembly and reduced size, eliminating the need for additional parts and deep-drawn bushings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If accessory components (priming valve, deep-drawn bushing) are added to ensure pump operation, then reliability is improved, but device dimensions increase and manufacturing complexity increases
Solution Approach 1:
The patent integrates the priming function directly into the valve assembly by configuring the first valve (suction valve) and second valve (discharge valve) with a through-hole arrangement that enables self-priming capability. This eliminates the need for a separate priming valve, reducing pump dimensions while maintaining operational reliability.
Solution Approach 2:
The patent removes the deep-drawn bushing component from the construction by adopting a modular design where the pump body can be assembled without this locking component. The valve assembly and pump body are designed to work together without requiring the bushing for structural integrity, thereby simplifying manufacturing and reducing part count.
2Reliability
If accessory components (priming valve, deep-drawn bushing) are added to ensure pump operation, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into the valve assembly: the first valve, second valve, and through-hole configuration work together to provide both flow control and self-priming capabilities. This integration reduces the number of separate components and simplifies the overall construction while ensuring reliable operation.
Solution Approach 2:
The valve assembly is designed to perform multiple functions: the first valve controls suction flow, the second valve controls discharge flow, and the through-hole arrangement enables self-priming. This multi-functionality eliminates the need for separate priming valve and bushing components, reducing complexity while maintaining reliability.
3Stability of the object's composition
If pump body is constructed with deep-drawn bushing locking mechanism, then structural stability is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The patent divides the pump into modular components: the pump body and the valve assembly can be separated and reassembled without requiring the deep-drawn bushing locking mechanism. This segmentation enables easy maintenance and inspection while maintaining structural stability during operation through proper sealing interfaces.
4Adaptability or versatility
If additional parts (priming valve) are added for self-priming capability, then self-priming function is improved, but manufacturing cost and production complexity increase
Solution Approach 1:
The patent integrates the self-priming function into the existing valve assembly design. The through-hole configuration of the valve body and the arrangement of the first and second valves work together to create the self-priming effect, eliminating the need for a separate priming valve and reducing manufacturing complexity.
Solution Approach 2:
The valve assembly is designed to perform multiple functions including flow control and self-priming. This multi-functionality is achieved through the through-hole arrangement and valve positioning, which enable the same components to provide both operational control and priming capability, thereby reducing part count and manufacturing cost.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows for a compact, easily assembled, and cost-effective vibration pump with enhanced self-priming capabilities, reducing noise and maintenance requirements while maintaining standardization and minimizing space and production costs.
Implementation Method 1
a coil (4) which generates a magnetic field for translating a moving piston (3)
Implementation Method 2
The upper elastic means have a silencing function, i.e. reduce the noise generated by the movement of the plunger in the communication conduit, by preventing impact thereof with the upper wall of the communication channel

AI summary
A vibration pump comprising a moving piston located in a pump body bounded by a coil, and cooperating with a second valve arranged in the discharge conduit formed in a communication conduit and with a first valve arranged in the communication conduit proximate to the suction port, which valves have a through hole therebetween. The first valve abuts the through hole at its top and the upper mouth of the moving piston at its bottom.
