Simulation Cabinet Inner Tank Hook Mounting to Minimize Thermal Bridges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In simulation cabinets, the attachment of the inner tank to the housing often results in thermal bridges that impair the simulated environmental conditions, particularly temperature distribution, due to contact between the inner tank and the housing.
Innovation Solution
The use of hook-shaped fastening elements on the inner tank and corresponding hooking elements on the housing allows for a secure attachment without direct contact, minimizing thermal bridges by using metal strips with recesses and projections that form easy-to-produce and easy-to-release fastening mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the inner vessel is attached to the housing using conventional fastening methods, then the inner vessel is securely fixed to the housing, but thermal bridges are created that impair the temperature distribution in the simulated environment
Solution Approach 1:
The patent introduces an intermediary element (the sheet metal strip with hook-shaped fastening elements) between the inner vessel and the housing. This intermediary allows mechanical attachment while minimizing direct thermal contact, as the hook-shaped elements engage with corresponding features on the housing without creating extensive thermal bridges, thus maintaining temperature distribution while providing secure attachment
Solution Approach 2:
The attachment system is segmented into discrete hook-shaped fastening elements rather than continuous contact. The sheet metal strip with multiple separate hooks provides secure attachment at specific points while leaving gaps that reduce thermal bridge formation, resolving the contradiction between attachment stability and temperature uniformity
2Strength
If screws or rivets are used to attach the inner vessel to the housing, then strong mechanical attachment is achieved, but the number of potential thermal bridges increases
Solution Approach 1:
The patent employs a simple sheet metal strip with hook-shaped elements that can be easily manufactured and replaced. This simple structure provides adequate mechanical attachment without creating the extensive thermal bridges associated with traditional screw or rivet assemblies, reducing heat loss while maintaining attachment functionality
Solution Approach 2:
The invention extracts the essential attachment function from complex fastening systems (screws, rivets) and implements it through simple hook-shaped elements. This extraction removes unnecessary components that would create thermal bridges while retaining the core mechanical attachment capability, thereby reducing heat loss
3Reliability
If multiple fastening means are used to securely attach the inner vessel, then attachment reliability is improved, but device complexity increases
Solution Approach 1:
The sheet metal strip with hook-shaped fastening elements serves multiple functions: it provides mechanical attachment, ensures electrical grounding, and maintains structural stability. This multi-functional design achieves reliable attachment without increasing device complexity, as a single component accomplishes what would otherwise require multiple separate fastening systems
