Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test chambers pose safety risks when testing dangerous materials like lithium-ion batteries, as the flexible membrane used for vibration decoupling and sealing can be destroyed during tests, leading to the escape of toxic gases and potential explosions, endangering operators and surrounding systems.
Innovation Solution
A test chamber design featuring a pressure-resistant and fireproof bulkhead with a thermal insulation layer that bridges the gap between the wall and the vibrator device, providing additional protection against explosions and chemical leaks, while maintaining vibration decoupling and temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible membrane is used to seal the gap between the wall and vibrator device, then vibration decoupling and sealing are achieved, but the membrane can be destroyed during tests with dangerous materials, leading to escape of toxic gases and potential explosions
Solution Approach 1:
The patent applies a composite structure consisting of a flexible membrane combined with a bulkhead. The membrane provides vibration decoupling and sealing, while the bulkhead adds structural strength and fire resistance. This composite approach maintains the benefits of the membrane while adding protective capabilities to prevent catastrophic failure when testing dangerous materials.
Solution Approach 2:
The bulkhead serves as a pre-prepared protective barrier that cushions against potential membrane failure. By having this additional protective structure in place before tests begin, the system is prepared to contain harmful effects if the membrane is destroyed during testing of dangerous materials like lithium-ion batteries.
2Ease of operation
If an opening is formed in the wall for the vibrator device, then vibration testing can be performed without subjecting the entire vibrator device to temperature changes, but air exchange between the test chamber and surroundings occurs, preventing effective temperature control
Solution Approach 1:
The flexible membrane seals the opening in the wall while allowing the vibrator device to pass through. This flexible sealing approach maintains the structural integrity and thermal insulation of the test chamber wall, preventing air exchange while accommodating the vibrator device for vibration testing operations.
3Reliability
If the vibrator device is sealed to the test chamber with a flexible membrane, then no air exchange occurs between the test chamber and environment, but the membrane can be easily damaged in case of explosion or fire, endangering operators and equipment
Solution Approach 1:
The patent combines a flexible membrane with a bulkhead to create a composite sealing structure. The membrane maintains sealing integrity and flexibility, while the bulkhead provides enhanced strength and resistance to explosion and fire, protecting operators and equipment from catastrophic failure.
Solution Approach 2:
The bulkhead acts as an intermediary protective element between the test chamber environment and the external surroundings. It mediates the transmission of extreme forces from explosions or fires, protecting the membrane and external equipment while maintaining the sealed environment necessary for temperature control.
