Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If moving parts are used to compact crystals in washing columns, then crystal bed formation is improved, but maintenance costs increase and operational reliability decreases
Solution Approach 1:
The patent removes moving parts from the washing column by extracting the compaction function to a separate stationary device located outside the column. This eliminates maintenance issues and operational interruptions while maintaining crystal bed formation capability.
Solution Approach 2:
A stationary compaction device with a porous plate acts as an intermediary between the washing column and crystal bed formation. This mediator compacts crystals without requiring moving parts inside the column, thus improving reliability while maintaining functionality.
2Ease of manufacture
If stationary flow resistance is used to compact crystals, then maintenance needs are reduced, but separation performance may be compromised
Solution Approach 1:
The patent replaces mechanical compaction systems with a stationary flow resistance mechanism. Fluid flow through the porous plate provides the compaction force, eliminating moving parts while maintaining effective crystal bed formation and separation performance.
Solution Approach 2:
The compaction process utilizes fluid flow (hydraulic principle) through a porous plate to compact crystals. This stationary hydraulic system achieves crystal bed formation without mechanical moving parts, reducing maintenance while preserving separation efficiency.
3Reliability
If washing columns handle reactive substances, then purification capability is improved, but spontaneous polymerization increases causing operational interruptions
Solution Approach 1:
The stationary compaction device prepares the crystal bed in advance before reactive substances are introduced to the washing column. This preliminary crystal bed formation creates a stable structure that prevents spontaneous polymerization during the purification process.
Solution Approach 2:
The patent extracts the crystal bed preparation process from the washing column operation itself, performing compaction separately using stationary equipment. This separation allows proper crystal bed formation without the harmful effects of moving parts, enabling safe handling of reactive substances.
