Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for setting up air conditioning in buildings using surface heat exchangers face challenges with thermal conductivity and logistical efficiency, as they require direct attachment of pipe systems to holding cassettes, leading to suboptimal heat transfer and increased logistical efforts.
Innovation Solution
A method involving a retaining cassette with a metal carrier plate at least 0.3 mm thick, where the pipe system is initially attached to the carrier plate with a protected adhesive layer, allowing for separate assembly at a remote location, enhancing thermal conductivity and reducing logistical burdens by enabling easier transport and handling of the intermediate product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pipe system is directly attached to the holding cassette at the manufacturing location, then the assembly process is simplified, but the thermal conductivity is suboptimal and logistical efforts increase
Solution Approach 1:
The system is divided into separate components: the holding cassette and the intermediate product (carrier plate with pipe system). This segmentation allows each component to be optimized independently - the carrier plate provides optimal thermal contact with the pipe system while the holding cassette provides mounting functionality, resolving the contradiction between ease of manufacture and thermal conductivity.
Solution Approach 2:
A metal carrier plate serves as an intermediary component between the holding cassette and the pipe system. This intermediate product improves thermal conductivity by providing a dedicated mounting surface for the pipe system, while still allowing for simplified manufacturing and assembly processes through separate production and later attachment.
2Productivity
If the finished surface heat exchanger is delivered in its entirety to the remote location, then the assembly is complete, but logistical effort and transport complexity increase
Solution Approach 1:
The surface heat exchanger is segmented into the holding cassette and the intermediate product, which can be transported separately. The intermediate product (carrier plate with pipe system) is more compact and easier to handle during transport, reducing logistical effort while still enabling complete assembly at the remote location.
Solution Approach 2:
The pipe system is preliminarily attached to the carrier plate at the manufacturing location, creating a pre-assembled intermediate product. This preliminary action reduces the complexity of final assembly at the remote location while optimizing transport characteristics, thereby reducing logistical effort and time.
3Reliability
If a carrier plate is introduced between the holding cassette and pipe system, then thermal conductivity is optimized, but device complexity increases
Solution Approach 1:
The carrier plate is merged with the pipe system to form a single intermediate product unit. This combining of functions (structural support, thermal conduction, and pipe mounting) into one component reduces overall device complexity while maintaining optimized thermal conductivity through the integrated design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach improves thermal conductivity and reduces logistical efforts by allowing for optimized heat transfer and easier handling and transport of the intermediate product, resulting in more efficient air conditioning systems with improved thermal performance and reduced manufacturing and installation costs.
Implementation Method 1
an adhesive layer and a protective layer covering the adhesive layer are arranged on the other side
Implementation Method 2
optimized heat conduction is initially ensured, since a carrier plate is arranged between the relatively thin holding cassette and the pipe system, which is able to optimally transfer the temperature or heat energy to be transferred to the holding cassette
