Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for handling hazardous substances in laboratories, such as solvents for chromatography, pose health risks to personnel and lack effective supply and disposal methods, with existing systems being poorly accepted due to safety concerns and inefficiencies.
Innovation Solution
A combination of a device working with hazardous substances and a safety cabinet, where the device is operationally connected to the cabinet via hoses for supply and disposal, featuring a control unit and sensor for measuring processed quantities, ensuring safe storage and monitoring of hazardous substances within a fire-resistant, transportable unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hazardous substances are stored in safety cabinets with self-closing mechanisms and fire-resistant structures, then safety protection is improved, but device complexity and operational convenience deteriorate
Solution Approach 1:
The patent combines the safety cabinet with the device operating with hazardous substances to form an integrated working unit. The cabinet serves both as storage and as the housing for the device, eliminating the need for separate safety infrastructure and reducing overall system complexity while maintaining safety functions.
Solution Approach 2:
The safety cabinet is designed to perform multiple functions: storing hazardous substances, housing the operating device, providing ventilation through extractors, and enabling transport via castors. This multi-functionality reduces the need for additional separate systems and simplifies the overall setup.
2Object-affected harmful factors
If hazardous substances are stored in safety cabinets, then health risks to personnel are reduced, but ease of operation deteriorates due to restricted access and vapor containment
Solution Approach 1:
The patent incorporates extractors that actively remove vapors from the cabinet interior and discharge them outside. This extraction system maintains a safe atmospheric environment inside the cabinet while allowing operators to work with hazardous substances without direct exposure to harmful vapors.
Solution Approach 2:
The cabinet acts as an intermediary barrier between the hazardous substances and the operator. By containing the substances within the sealed cabinet structure and using hoses for fluid transfer, the system mediates the interaction between operator and hazardous material, reducing direct health risks while maintaining operational capability.
3Reliability
If devices are connected to safety cabinets via hoses for supply and disposal, then safety and acceptance are enhanced, but device complexity and setup time increase
Solution Approach 1:
The device is integrated into the cabinet structure with hoses internally routed and connected. This merging of the device and cabinet into a single unit eliminates the need for external hose connections and complex setup procedures, while maintaining the safety benefits of contained hazardous substance handling.
4Adaptability or versatility
If safety cabinets are made transportable with castors, then operational flexibility is improved, but stability and security during operation may deteriorate
Solution Approach 1:
The cabinet is designed with castors for mobility but can be positioned and stabilized during operation. The dynamic capability to move when needed combined with the ability to remain stationary during use provides both flexibility and stability, adapting to different operational requirements.
