Solution Overview
Problem
Existing high-pressure cleaners face challenges in arranging the operating element and actuating element in an offset configuration, which complicates the actuation of components like pumps that are vibrating relative to the housing.
Innovation Solution
The solution involves connecting the operating element and actuating element in a rotationally fixed manner via at least one universal joint, allowing for an offset arrangement and enabling movement of the actuating element relative to the operating element while maintaining actuation capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operating element and actuating element are arranged coaxially, then the actuation mechanism is simple, but the design flexibility and adaptability to vibrating components is limited
Solution Approach 1:
A universal joint is introduced as an intermediary component between the operating element and actuating element. This universal joint serves as a mediator that transmits rotational motion while accommodating angular misalignment, thereby enabling offset arrangement of the elements without compromising actuation functionality.
Solution Approach 2:
The universal joint introduces dynamic adaptability to the system by allowing the actuating element to move relative to the operating element in the direction of the actuating rotation axis. This dynamic capability enables the system to bridge different distances and accommodate vibrations while maintaining reliable actuation.
2Adaptability or versatility
If the actuating element is attached to a vibrating component, then the design accommodates real-world operating conditions, but the connection stability and actuation reliability deteriorate
Solution Approach 1:
The universal joint enables dynamic movement of the actuating element relative to the operating element, allowing the system to accommodate vibrations from the pump component. The actuating element can move in the direction of the actuating rotation axis while maintaining functional connection, ensuring reliable actuation despite vibrational disturbances.
Solution Approach 2:
The universal joint acts as a vibration-isolating intermediary between the vibrating pump component and the operating element. It absorbs and accommodates vibrational movements while maintaining the actuation connection, thereby preserving actuation reliability in vibrating environments.
3Adaptability or versatility
If two universal joints are used to connect the operating element and actuating element, then the positioning flexibility is improved, but the device complexity increases
Solution Approach 1:
The first universal joint allows movement of the connecting piece relative to the operating element, while the second universal joint allows movement of the actuating element relative to the connecting piece. This dual-joint configuration provides enhanced dynamic positioning flexibility, enabling the system to accommodate complex relative movements and vibrations while maintaining actuation functionality.
