Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid support structure is used to keep the filter element from collapsing, then structural integrity is maintained, but installation difficulty increases
Solution Approach 1:
The filter element transitions from a static rigid structure to a dynamic flexible structure that can adapt its shape. The flexible membrane allows the filter element to be compressed into a compact insertion configuration for easy installation, then expand to a radially protruding operational configuration to maintain structural integrity and filtering effectiveness.
Solution Approach 2:
The physical state of the filter element changes from rigid to flexible, altering its mechanical properties. This parameter change enables the element to be deformed during installation and then return to its functional shape, resolving the contradiction between ease of installation and structural integrity.
2Ease of operation
If a flexible membrane is used to enable folding, then installation ease is improved, but structural integrity may be compromised
Solution Approach 1:
The filter element transitions from a static rigid structure to a dynamic flexible structure that can adapt its shape. The flexible membrane allows the filter element to be compressed into a compact insertion configuration for easy installation, then expand to a radially protruding operational configuration to maintain structural integrity and filtering effectiveness.
Solution Approach 2:
The filter element is divided into multiple pleated or folded sections that can independently deform. This segmentation allows the element to be compressed during installation while maintaining the overall structural framework, and then expand to provide sufficient structural integrity during operation.
3Strength
If a radially protruding configuration is maintained, then structural integrity is preserved, but insertion difficulty increases
Solution Approach 1:
The filter element transitions from a static rigid structure to a dynamic flexible structure that can adapt its shape. The flexible membrane allows the filter element to be compressed into a compact insertion configuration for easy installation, then expand to a radially protruding operational configuration to maintain structural integrity and filtering effectiveness.
Solution Approach 2:
The filter element is pre-compressed into a compact insertion configuration before installation. This preliminary action reduces its size to facilitate easy insertion through the reservoir opening, after which it automatically expands to its functional radially protruding configuration.

AI summary
The disclosure relates to a filter assembly for a windshield washer fluid reservoir. The assembly includes a tubular piece to be connected to a pump and a hollow filter element with an inlet attached to the tubular piece and in fluid communication with it. The hollow filter element, when inserted through a hole in the windshield washer fluid reservoir, adopts an insertion configuration, in which it is folded to at least partially surround the tubular piece. The hollow filter element elastically returns to an operating configuration in which it protrudes radially from the tubular piece.
