Cistern Hydraulic Lifting Device Integrated Housing Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cisterns with hydraulic actuation of drain fittings are complex to install due to the need for multiple components and small inspection openings, increasing the risk of errors during assembly.
Innovation Solution
A compact, one-piece housing block containing both the lifting and trigger elements, connected via a fastening element that engages with recesses in the cistern wall, simplifies installation and reduces the risk of errors by providing a single, easy-to-handle element for assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate components are used for hydraulic actuation, then the lifting device can perform complex functions, but the assembly becomes extremely laborious and time-consuming due to the small inspection opening
Solution Approach 1:
The patent combines the cylinder, piston, sealing elements, and fastening components into a single integrated housing block. This merging of previously separate components into one pre-assembled unit eliminates the need for complex step-by-step assembly through the small inspection opening, while maintaining all necessary hydraulic actuation functions.
2Adaptability or versatility
If multiple separate components are used for hydraulic actuation, then the lifting device can perform complex functions, but the risk of errors during assembly increases
Solution Approach 1:
By pre-assembling all hydraulic components (cylinder, piston, seals, fastening elements) into an integrated housing block before installation, the patent eliminates multiple connection steps that could lead to assembly errors. The integrated design ensures proper positioning and connection of all components, reducing the risk of installation mistakes.
3Device complexity
If a compact integrated housing block is used, then the installation becomes simple and efficient, but the internal arrangement of components must be highly optimized
Solution Approach 1:
The housing block is pre-assembled with all hydraulic components (cylinder, piston, sealing elements, fastening components) integrated before final installation in the cistern. This preliminary assembly allows for optimized internal arrangement and testing to be completed beforehand, simplifying the on-site installation process while ensuring proper component positioning.
