Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation sterilization installations require multiple heavy and costly radiation generating devices to ensure effective sterilization, which increases operational complexity and health risks due to radiation leaks.
Innovation Solution
A sterilization installation that uses a single radiation generator by moving and rotating articles in a circular path with dual rotating platforms, allowing all surfaces to be exposed to radiation, including inversion of articles to treat both sides with a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple radiation-generating devices are used to ensure effective sterilization of all article surfaces, then sterilization completeness is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies the dynamics principle by making the article support device movable instead of stationary. The support device rotates around a first axis and articles rotate around a second axis, creating dynamic motion that allows a single radiation generator to treat all surfaces of articles from multiple angles, eliminating the need for multiple fixed radiation sources
Solution Approach 2:
The patent implements dimensionality change by introducing rotational motion around two different axes. The support device rotates around a first axis while articles simultaneously rotate around a second axis, adding temporal and spatial dimensions to the sterilization process, allowing one generator to achieve what would otherwise require multiple generators positioned at different locations
2Reliability
If multiple radiation-generating devices are arranged to treat different parts of articles, then sterilization coverage is improved, but weight and space requirements increase
Solution Approach 1:
By implementing rotational motion of the support device and articles, the system dynamically redirects a single radiation generator to treat different parts of articles over time, eliminating the need for multiple heavy radiation-generating devices that would be required to treat all surfaces simultaneously from multiple positions
3Device complexity
If articles are treated with a single radiation generator, then device complexity is reduced, but treated surface area is limited
Solution Approach 1:
The support device rotates around a first axis while articles rotate around a second axis, creating dynamic motion that brings different surfaces of articles into the radiation path over time. This temporal dimension allows a single generator to treat the entire surface area of articles sequentially, achieving complete coverage without requiring multiple generators
Solution Approach 2:
By adding rotational motion around two axes, the system transforms a static single-point radiation treatment into a dynamic multi-angle treatment process, effectively expanding the treated surface area over time through temporal and spatial dimensionality changes
