Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile sterilization cabinet is equipped with wheels for maneuverability, then ease of movement is improved, but stability during sterilization operation deteriorates
Solution Approach 1:
The cabinet is divided into a stationary base structure and a movable upper section. The base remains fixed during sterilization operations to ensure stability, while the upper section can be moved independently when needed, resolving the contradiction between maneuverability and operational stability.
Solution Approach 2:
The cabinet incorporates a dynamic locking mechanism that transitions the cabinet from a movable state during transport to a fixed, stable state during sterilization operations. This dynamic adjustment allows the same cabinet to satisfy both maneuverability and stability requirements under different operational conditions.
2Reliability
If filters are positioned inside the cabinet for contamination prevention, then sterility protection is improved, but accessibility for inspection and replacement deteriorates
Solution Approach 1:
An intermediary access panel or removable cover is introduced between the external environment and the internal filters. This intermediary element can be opened to provide access to filters for inspection and replacement, while remaining closed during sterilization to maintain sterility protection, thus resolving the contradiction between protection and accessibility.
Solution Approach 2:
The filter system is designed with nested components where outer protective covers can be removed to access inner filters. This nested structure allows filters to remain protected within the cabinet while providing a clear path for inspection and replacement when the outer covers are removed.
3Productivity
If vents are provided for steam circulation during sterilization, then sterilization effectiveness is improved, but risk of water retention and contamination deteriorates
Solution Approach 1:
The vent system incorporates hydrophobic coating or membrane technology that selectively allows steam molecules to pass through while blocking liquid water. This functional differentiation enables effective steam circulation for sterilization while preventing water retention and subsequent contamination risks.
Solution Approach 2:
The vents utilize porous materials with specific pore size distributions that permit steam penetration for effective sterilization circulation while preventing liquid water from passing through. The porous structure provides the necessary selectivity to resolve the contradiction between sterilization effectiveness and water retention prevention.

Implementation Method 1
affixing an edge of a filter cover against the sterilization container to engage the second filter directly against the first filter and the first filter against the panel such that the edge forms a seal
Implementation Method 2
Vent 35 is covered by a filter 50, and a filter cover 55 holds filter 50 in place against vent 35

AI summary
A sterilization cabinet, comprising a top panel, at least two side panels, and a floor panel forming a part of a chamber of the sterilization cabinet; at least one door connected to at least one of the at least two sider panels of the sterilization cabinet; a vent formed in at least one of the two side panels; at least one first filter covering the vent and a filter cover configured to hold the first filter against the vent; a drain positioned in the floor panel, wherein the floor panel has a slope configured to cause condensate within the chamber to flow into the drain and wherein the drain is the only outlet for the condensate along the floor panel; and a second filter covering the drain such that condensate flowing into the drain passes through the second filter.
