Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biological liquid treatment installations face challenges in achieving secure, convenient, and economical operations, particularly with single-use components that require complex selection, assembly, and verification processes, especially under high pressure and with numerous components.
Innovation Solution
A device with a jamming system that fixes a bag in place using jamming nipples and channels, ensuring the bag remains stationary during treatment, and allows for easy replacement and adaptation for different treatments, utilizing a modular circuit with interchangeable shells and bags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If single-use components are used in biological liquid treatment installations, then cleaning operations are avoided, but selection, assembly and verification operations become relatively complex
Solution Approach 1:
The system divides the treatment installation into separate modular units (source container, treatment containers, collecting container, waste container) that can be independently selected and assembled. Each container is a discrete single-use component with standardized connectors, allowing complex treatment protocols to be broken down into manageable modular units that can be quickly configured and verified.
2Adaptability or versatility
If the number of pipes and circuit components is high, then treatment functionality is improved, but selection, assembly and verification operations become more complex
Solution Approach 1:
The system employs universal connectors and standardized interface designs that allow the same connector type to interface with multiple different container types and treatment stages. This universality reduces the variety of unique components needed, simplifying selection and assembly while maintaining comprehensive treatment functionality through modular configuration.
3Reliability
If operating pressure is high, then treatment effectiveness is improved, but selection, assembly and verification operations become more complex and less secure
Solution Approach 1:
The system incorporates pressure-rated single-use components designed from the outset to withstand high operating pressures. The containers and connectors are manufactured with inherent pressure containment capabilities, eliminating the need for complex assembly verification procedures to ensure pressure safety. The single-use nature means the components are pre-tested and certified for their pressure ratings before deployment.
4Duration of action of stationary object
If conventional stainless steel installations are used, then treatment durability is improved, but cleaning operations become onerous
Solution Approach 1:
The system replaces durable but difficult-to-clean stainless steel components with disposable single-use plastic containers and circuit elements. These single-use components are designed to be discarded after one use, eliminating all cleaning operations entirely. The trade-off is accepting shorter component lifespan in exchange for complete elimination of cleaning requirements and associated operational complexity.
