Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional class 3 glove boxes are used to meet safety standards, then protection against harmful material is ensured, but the weight and complexity make them non-portable
Solution Approach 1:
The glove box system is divided into separate modular components including the glove box chamber, HEPA filter assembly, vacuum pump, and power supply. Each component can be independently handled and transported, with the main chamber weighing under 100 lbs while other components are separately carried and connected at the deployment location.
Solution Approach 2:
The design changes the weight parameter by using lightweight materials such as aluminum or plastic for the glove box chamber instead of traditional heavy metals, while maintaining the structural integrity and safety requirements through optimized design and material selection.
2Reliability
If conventional class 3 glove boxes are designed for laboratory use, then safety standards are met, but they lack ruggedness for mobile operations
Solution Approach 1:
The system separates the fragile HEPA filter and pump components from the rugged glove box chamber. The chamber is designed as a robust, portable unit that can withstand mobile operations, while sensitive components are housed in separate protective cases and connected via sealed interfaces that maintain integrity during transport.
Solution Approach 2:
The glove box chamber and components are designed with protective features including reinforced corners, cushioned interiors, and shock-absorbing mounting structures that prepare the system for rough handling and mobile deployment conditions while maintaining safety standards.
3Reliability
If conventional glove boxes rely on laboratory infrastructure, then operational requirements are met, but portability to remote locations is prevented
Solution Approach 1:
The portable power supply is integrated with the vacuum pump and control systems, creating a self-contained unit that operates independently of laboratory infrastructure. The combined system includes battery or generator power, vacuum generation, HEPA filtration, and glove box operation all in one portable configuration.
Solution Approach 2:
The glove box system is designed as a universal platform that can be deployed in various environments including remote field locations, laboratories, and mobile platforms. The modular design allows the same core system to adapt to different operational settings without requiring location-specific infrastructure.
4Weight of moving object
If lightweight materials are used to reduce weight, then portability is improved, but maintaining class 3 safety standards becomes difficult
Solution Approach 1:
The glove box chamber uses composite construction combining lightweight materials such as aluminum alloys or reinforced plastics with protective coatings and sealed joint systems. This composite approach achieves the required strength-to-weight ratio to maintain safety standards while enabling portability.
Solution Approach 2:
The safety-critical functions (HEPA filtration, vacuum maintenance, sealing) are separated into dedicated modular components with robust construction, while the main chamber uses lightweight materials. This segmentation allows lightweighting where possible while maintaining safety functions with proven reliable components.

AI summary
A glove box for handling harmful material is formed to be lightweight and modular in design, allowing for use in the field and various remote locations where a full laboratory is not available. The tank portion of the glove box is formed of a rigid, lightweight plastic and includes a number of standard-sized passageways for connecting other components (intake filter, exhaust filter, input/output containers, gasketed gloves, etc), allowing for modularity in its configuration. The top portion of the glove box may include a transparent window for viewing the material within the glove box. Filter components utilize HEPA filter elements and a separate, portable power supply is used to control a vacuum fan included in an exhaust filter. The power supply can also be used to perform diagnostic tests on the glove and may include a battery back-up.
