Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RF isolation containers pose ergonomic and safety issues due to the need for significant operator pressure to lock and unlock the lid, potential gas cylinder failures during maintenance, and difficulties in cleaning, leading to health risks and maintenance challenges.
Innovation Solution
An RF isolation container featuring a counterweight for easy lid operation, an electromagnet locking mechanism for reduced operator effort, and motion dampers to minimize wear and strain, along with a metallic gasket for consistent sealing and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional locking mechanism is used that relies on operator pressure to lock the lid against gaskets, then the lid can be secured in place, but significant additional pressure must be exerted by the operator which leads to health and safety issues such as repetitive strain injury
Solution Approach 1:
The patent replaces the conventional mechanical locking mechanism that requires manual pressure with an electromagnetic locking mechanism. The electromagnet attracts the lid to the base when energized, providing reliable locking without requiring the operator to exert significant physical pressure, thereby eliminating repetitive strain injury risks while maintaining secure closure.
2Ease of operation
If gas cylinders are used to support the lid in open position, then the lid can be easily opened and held, but the gas cylinders may fail unexpectedly causing safety issues when workers have hands inside the container
Solution Approach 1:
The patent employs a counterweight system that automatically balances the lid weight, allowing the lid to be easily opened and held in position without active support components. The counterweight provides passive mechanical assistance through gravitational balance, eliminating the need for gas cylinders that could fail and posing safety risks to operators.
3Reliability
If a grooved joint with metallic mesh gasket is used to ensure electrical contact between lid and base, then RF isolation is maintained, but dust and material accumulate in the grooved joint making it difficult to clean
Solution Approach 1:
The patent removes the grooved joint structure entirely and replaces it with a flat sealing surface. The metallic mesh gasket is positioned on the flat surface rather than within a groove, eliminating the cavity where dust and material would accumulate. This maintains RF isolation through the gasket's electrical properties while allowing the flat surface to be easily wiped clean without complex disassembly.
