Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high manufacturing precision requirements are imposed on mutually matched components, then mounting alignment accuracy is improved, but manufacturing costs increase
Solution Approach 1:
The patent introduces a movable connection mechanism that changes the connection parameter from rigid fixed to flexible movable, allowing automatic compensation for dimensional variations and mounting alignment errors without requiring high manufacturing precision
Solution Approach 2:
The wastewater pipeline is designed with movable connection capabilities, transforming from a static rigid connection to a dynamic adjustable connection that can adapt to positional deviations during mounting
2Stability of the object's composition
If the wastewater pipeline is made rigid to maintain structural stability, then structural stability is improved, but mounting flexibility and adaptability are reduced
Solution Approach 1:
The patent applies dynamic connection mechanisms to the wastewater pipeline, enabling it to maintain structural integrity while accommodating mounting position variations through movable joints
Solution Approach 2:
The wastewater collecting pipe is nested within the pure water collecting pipe, with the wastewater pipeline forming a cantilever structure that provides both stability and flexibility
3Adaptability or versatility
If the wastewater collecting pipe is made flexible to improve mounting adaptability, then mounting flexibility is improved, but structural strength is reduced
Solution Approach 1:
The wastewater collecting pipe is nested within the pure water collecting pipe, forming a cantilever structure that distributes mechanical loads and maintains structural strength while allowing flexibility for mounting alignment
4Device complexity
If multiple separate pipes are used for pure water and wastewater collection, then functional clarity is improved, but device complexity and space occupation increase
Solution Approach 1:
The wastewater collecting pipe is nested within the pure water collecting pipe, with concentric arrangement of pure water and wastewater passages, reducing component quantity and space occupation while maintaining functional clarity through distinct separated flow paths
Solution Approach 2:
The patent combines the pure water collecting pipe and wastewater collecting pipe into a single central pipe assembly, merging multiple functions into an integrated structure

AI summary
The present invention relates to a filter element and a filter having the filter element. The filter element comprises a filter element housing part, a water inlet disposed at the filter element housing part, a filter medium unit disposed in the filter element housing part, and a central pipe. The central pipe comprises a pure water collecting pipe and a wastewater collecting pipe, and the wastewater collecting pipe is at least partially disposed in the pure water collecting pipe. A wastewater passage and a pure water passage are arranged sequentially from the center to the circumference in the central pipe. The filter element and the filter according to the present invention has a more simplified filter element structure. By reducing the quantity of components, the filter is made more compact. The present invention can further accommodate positional errors within an allowed error range when the filter element is mounted to a local manifold 1 of the filter. Manufacturing precision requirements of filter components can thus be lowered and the cost can be reduced. The replacement and mounting of the filter element have therefore become easier.
