Repositionable Pump Operating Unit for Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pump assemblies often have display and operating elements that are poorly accessible or visible due to their installation location and position, making it difficult to operate and monitor them effectively.
Innovation Solution
A pump assembly design where the operating unit is a separate, releasably connectable component that can be attached to the housing in multiple positions, allowing for flexible placement and visibility, with signal connection options including optical, electrical, and wireless methods, and featuring a non-positive or positive fit for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the operating unit is integrated in a fixed manner into the first housing, then the device complexity is reduced, but the accessibility and visibility of operating elements and display elements deteriorate at different installation locations and positions
Solution Approach 1:
The operating unit is separated from the first housing into an independent, releasably connectable component. This segmentation allows the operating unit to be positioned independently to optimize accessibility and visibility while maintaining a relatively simple overall device structure through modular design.
Solution Approach 2:
The operating unit is designed to be repositionable between multiple installation positions on the first housing. This dynamic positioning capability allows the operating elements and display elements to be optimally accessible and visible depending on the specific installation location and pump assembly orientation.
2Ease of manufacture
If the operating unit is integrated in a fixed manner into the first housing, then the manufacturing process is simplified, but the adaptability to different installation positions deteriorates
Solution Approach 1:
The operating unit is designed as a universal component that can be installed in multiple positions on the first housing. This multi-functional design allows a single operating unit to serve different installation scenarios (different locations and positions) without requiring multiple specialized pump assemblies, thereby maintaining ease of manufacture while improving adaptability.
Solution Approach 2:
The repositionable design of the operating unit provides adaptability to different installation positions while maintaining a standardized manufacturing process. The operating unit can be manufactured once and then installed in various positions depending on the specific application requirements.
3Ease of operation
If the operating unit is made repositionable in multiple positions, then the accessibility and visibility of operating elements improve, but the device complexity increases
Solution Approach 1:
By segmenting the operating unit as a separate, releasably connectable component, the patent achieves repositionability without substantially increasing overall device complexity. The modular design allows for easy installation and repositioning while maintaining a relatively simple structure.
Solution Approach 2:
The operating unit's position parameter can be changed between multiple installation positions without fundamentally altering the device structure. This parameter change approach allows for improved accessibility and visibility while minimizing increases in device complexity.
4Adaptability or versatility
If the operating unit is made repositionable in multiple positions, then the adaptability to different installation locations improves, but the manufacturing complexity increases
Solution Approach 1:
The operating unit is designed as a universal component that can be manufactured once and installed in multiple positions. This universality maintains ease of manufacture while providing high adaptability to different installation locations and positions.
Solution Approach 2:
The dynamic repositioning capability is achieved through a standardized connection interface that allows the operating unit to be installed in various positions without requiring complex manufacturing processes. The same operating unit can serve multiple installation scenarios.
