Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filters for heating and cooling systems require complex and costly installations with additional components, such as shut-off valves, to facilitate maintenance and impurity removal, which is inefficient and costly, especially in modern systems with limited space.
Innovation Solution
A filter design incorporating a shut-off element that allows for maintenance without additional components, enabling easy isolation and cleaning of the filtering elements within the filter chamber without draining the entire system, utilizing a magnetic filtering element and a mechanical filtering element for comprehensive impurity removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional filters are used with shut-off valves for maintenance, then impurity removal capability is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent combines the shut-off function and filter housing into a single integrated body. The piston element serves both as a shut-off mechanism and as part of the filter structure, eliminating the need for separate shut-off valves and reducing installation complexity while maintaining impurity removal capability
Solution Approach 2:
The piston element performs multiple functions: it acts as a shut-off valve to isolate the filter chamber, serves as a mechanical advantage lever for opening the chamber, and integrates with the filter body structure. This multi-functionality reduces the number of components needed while maintaining reliable impurity removal
2Ease of repair
If traditional filters with separate shut-off valves are used, then maintenance access is improved, but cost increases
Solution Approach 1:
The shut-off valve and filter housing are merged into a single integrated body, reducing the number of parts that need to be manufactured and assembled. This integration lowers manufacturing costs while maintaining ease of maintenance through the piston mechanism
Solution Approach 2:
The piston mechanism allows the filter chamber to be opened and closed by the user without requiring external tools or additional components. The mechanical advantage provided by the piston lever enables easy operation, making maintenance accessible while reducing manufacturing complexity
3Reliability
If the entire system is drained for filter maintenance, then complete impurity removal is improved, but loss of time and operational disruption increase
Solution Approach 1:
The filter chamber is extracted as a separate, isolatable compartment from the main system. The piston shut-off mechanism allows the chamber to be sealed off and opened independently without draining the entire system, enabling maintenance while minimizing system downtime and preserving operational fluid
