Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing ceramic adsorption structures used in water treatment systems are prone to water leakage due to differential pressure, leading to reduced durability and increased frequency of replacement, which affects capacity utilization and adsorption performance.
Innovation Solution
A ceramic filter structure with a water-impermeable outer tube and a seal material to prevent water leakage, combined with a housing and ring members for enhanced sealing, ensuring that feed water passes through the partition wall without leaking, thereby improving durability and adsorption efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dense outer wall is used to prevent water leakage, then water-tightness is improved, but the outer wall may crack due to differential pressure and surface pressure from packing
Solution Approach 1:
The outer wall is constructed as a composite structure combining a dense ceramic layer for water-tightness with a porous ceramic layer for pressure absorption. This composite material approach allows the dense layer to prevent leakage while the porous layer absorbs differential pressure, preventing cracking and maintaining both water-tightness and structural strength.
2Duration of action of stationary object
If the adsorption structure is made durable with dense ceramic walls, then lifespan is extended, but replacement frequency increases when cracking occurs due to pressure
Solution Approach 1:
The porous ceramic layer is designed in advance to absorb and cushion differential pressure before it can reach the dense outer wall. This prior cushioning mechanism prevents pressure-induced cracking and extends the adsorption structure lifespan by protecting the structural integrity under pressure conditions.
3Reliability
If water leakage is prevented through better sealing, then adsorption performance is maintained, but manufacturing complexity increases
Solution Approach 1:
The porous ceramic material serves dual functions: it acts as a pressure-absorbing cushion to prevent outer wall cracking and maintains adsorption performance through its adsorptive properties. This eliminates the need for additional complex sealing mechanisms, as the porous structure inherently manages both pressure and fluid flow, simplifying manufacturing while maintaining reliability.

AI summary
An adsorption structure unit prevents water leakage from an adsorption structure and improves the durability of the adsorption structure and the durability of the adsorption structure unit. An adsorption structure has a filter portion having a plurality of flow paths divided by a plurality of partition walls and a plugged portion shutting a feed water inflow or outflow end of the plurality of flow paths, a water-impermeable outer tube accommodating the filter portion, and a seal material blocking a gap between the filter portion and the outer tube in at least one end portion of the filter portion. An adsorption structure unit has the adsorption structure, a housing supplying feed water from one end of the adsorption structure, and discharging the feed water from the other end, and a ring member disposed between end portions on both sides of the outer tube and an inner surface of the housing.
