Solution Overview
Problem
Existing electrolytic reactors, particularly tubular designs, suffer from inefficiencies in space utilization, complex electrical connections, and difficulty in maintenance due to welded construction and inadequate sealing methods, leading to issues with pressure operation and corrosion resistance.
Innovation Solution
A rectangular plastic housing with integrated metal fasteners and threaded end cap anchors allows for pressurized operation, improved sealing, and easy assembly/disassembly, along with welded electrode connectors for secure electrical connections and alignment slots for precise electrode placement, enhancing maintenance and space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tubular reactor housing is used, then the reactor can be sealed and operate under pressure, but the space utilization is inefficient with void areas between plates and housing wall
Solution Approach 1:
The reactor housing is segmented into a rectangular cross-section design with plates arranged to eliminate void spaces, dividing the housing interior into efficient flow channels that maximize active treatment volume while maintaining pressure containment capability
Solution Approach 2:
The design transitions from a curved tubular housing to a rectangular housing with flat plates, optimizing the use of cubic space to eliminate wasted void areas while the rounded corners on the rectangular housing maintain stress distribution for pressure operation
2Ease of manufacture
If traditional bolts and nuts are used for electrical connections, then the reactor can be assembled, but the sealing is insufficient and requires sealing compound for maintenance
Solution Approach 1:
A flexible sealing gasket is introduced between the housing and end caps, providing reliable sealing that accommodates assembly tolerances and maintains integrity during maintenance operations without requiring additional sealing compounds
Solution Approach 2:
The sealing gasket acts as an intermediary element between the rigid housing and end caps, transferring and distributing compression forces to create a reliable seal while allowing the electrical connection components to be securely fastened
3Strength
If the reactor components are welded together, then the structure is strong, but the reactor cannot be disassembled for maintenance or repair
Solution Approach 1:
The reactor is divided into separable modules (housing, end caps, plate assemblies) connected by mechanical fasteners instead of welds, allowing individual components to be removed for maintenance while maintaining structural integrity during operation
Solution Approach 2:
The connection system transitions from a permanent welded state to a dynamic, reversible fastening system that provides structural strength during operation and enables easy disassembly during maintenance through threaded fasteners
4Volume of moving object
If a rectangular housing is used, then space utilization is improved, but complex electrical connector arrangements make it difficult to seal the reactor
Solution Approach 1:
The electrical connector arrangements are merged with the end cap assembly and integrated into the sealing system, where the end caps provide both electrical connection points and sealing surfaces, simplifying the overall design while maintaining rectangular housing space efficiency
Applied Scientific Principles

Function Achieved in This Case
The solution enables efficient operation under pressure with improved sealing, reduced maintenance needs, and enhanced corrosion resistance, allowing for effective water treatment while optimizing space usage and facilitating easy handling and interchangeability of reactor components.
Implementation Method 1
The process of electrocoagulation involves passing contaminated water between electrodes connected to a source of DC power. The high voltage potential applied to the electrodes forces metal ions to liberate from the surface of electrodes and into the water, causing impurities to coagulate into a larger and denser solid
Implementation Method 2
The applied DC power forces metal ions to release from the electrodes and mix into the water, thus generating a concentrated solution of metal ions that can be added directly to contaminated water
