Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If filters are arranged in a row to allow purified water to flow toward a certain direction, then the water purification function is achieved, but the space efficiency is reduced and the device complexity increases
Solution Approach 1:
The patent transitions from a linear one-dimensional filter arrangement to a three-dimensional spatial configuration where filters are positioned at different levels and angles within the housing. The pipe member extends diagonally and connects filters in a non-linear pattern, utilizing vertical and horizontal spaces simultaneously to reduce the overall footprint while maintaining purification capacity
2Device complexity
If a conventional linear filter arrangement is used, then the structure is simple, but the flow path resistance increases and purification efficiency decreases
Solution Approach 1:
The patent employs curved and angled pipe connections instead of straight linear paths. The pipe member extends at specific angles (e.g., 45 degrees) and includes curved sections that optimize water flow dynamics, reducing turbulence and resistance while maintaining a relatively simple overall structure. The curved geometry allows for smoother transitions between filters
3Volume of moving object
If multiple filters are connected in a compact arrangement, then space efficiency is improved, but the risk of incorrect coupling increases
Solution Approach 1:
The patent incorporates asymmetric connection interfaces where male and female coupling parts have non-symmetric geometries. This ensures that filters can only be coupled in the correct orientation, preventing incorrect assembly. The asymmetric design includes specific angular orientations and non-uniform connection features that guide proper installation while maintaining compact filter spacing

AI summary
A filter assembly comprises an outer casing, filters and a pipe member connected to first, second and third filters and comprising an inlet flow path and an outlet flow path. The inlet flow path comprises a first inlet flow path connected to the first filter, a second inlet flow path connected to the second filter, a third inlet flow path connected to the third filter, and an inflow member comprising a branch point to allow water to flow in parallel through the first inlet flow path and the second inlet flow path. The outlet flow path comprises a first outlet flow path for water to be discharged from the first filter, and a second outlet flow path for water to be discharged from the second filter. Water discharged from the first outlet flow path from the second outlet flow path is guided and introduced into the third inlet flow path.
