Prefabricated Locking Unit for High-Pressure Cleaner Push Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-pressure cleaning devices are difficult to assemble cost-effectively and efficiently, with a risk of assembly errors due to the need for multiple components and complex assembly steps.
Innovation Solution
A prefabricated unit incorporating an actuating member, coupling member, and locking member, made of plastic, which simplifies assembly by allowing the unit to be positioned in a single step, reducing the number of components and assembly errors, and enabling easy movement and locking of the push handle in different positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components are used for the locking device, then the locking function can be achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines the actuating member, coupling member, and locking member into a single integrated locking device assembly. This merging of previously separate components simplifies the assembly process while maintaining the complete locking functionality, directly resolving the contradiction between reliable locking and complex assembly.
2Reliability
If multiple separate components are used for the locking device, then the locking function can be achieved, but assembly errors may occur
Solution Approach 1:
By integrating multiple components into a pre-assembled locking device unit, the patent eliminates potential assembly errors that would occur when manually assembling separate parts. The integrated design ensures precise positioning and proper functioning without requiring complex assembly procedures.
3Productivity
If a prefabricated unit is used for the locking device, then assembly time is reduced, but the device structure becomes more integrated
Solution Approach 1:
The patent applies segmentation by dividing the high-pressure cleaning device into functional modules, with the locking device as a self-contained prefabricated unit that can be independently produced and then integrated. This modular approach enables rapid assembly of the overall device while managing structural complexity through standardized interfaces.

AI summary
A high-pressure cleaning appliance is provided, including a housing having a motor and a pump, driven by the motor, arranged therein, and including at least two rotatably mounted running wheels, a push bar movable back and forth between a parking position and an operating position, and a locking device for releasably locking the push bar, the locking device including an actuating member which is coupled by at least one coupling member to at least one locking member which interacts with the push bar and is movable from a locking position to a release position by actuating the actuating member. So that the high-pressure cleaning appliance can be assembled more cost-effectively and more easily, the locking device includes a prefabricated constructional unit which forms the actuating member, the at least one coupling member and the at least one locking member and is movably mounted on or in the housing.
