Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigeration devices with aluminum containers are costly to produce, have complex manufacturing processes, and suffer from poor cleanability due to folded edges and weld seams, while the winding process of refrigerant tubes is slow and inefficient due to varying distances between the tube and container.
Innovation Solution
A device that maintains a constant angle and distance between the rotary shaft and the container during tube winding, using a tiltable and adaptable rotary shaft with a tube bending roller and pressure roller to apply adhesive tape, allowing for high-speed and precise tube winding on containers of various shapes, including plastic, and enhancing heat transfer with an aluminum adhesive tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the container is rotated about its axis during tube winding, then the tube can be wound helically onto the container, but the distance between the tube guide and container surface changes greatly, requiring very slow rotation speed
Solution Approach 1:
The patent applies dynamics by making the rotary shaft tiltable and adjustable in position. The shaft can be tilted at a specific angle and moved perpendicular to its axis of rotation, allowing the tube guide to maintain a constant distance from the container surface throughout the winding process. This dynamic adjustment resolves the contradiction by enabling both high rotation speeds and consistent tube placement.
Solution Approach 2:
The patent changes the parameters of the rotary shaft system by introducing tiltable capability and perpendicular movement. By adjusting the shaft angle and position, the system maintains optimal geometric conditions for tube winding, enabling high-speed operation while preserving manufacturing precision through parameter optimization.
2Ease of manufacture
If aluminum containers with folded edges and weld seams are used, then the manufacturing process is established, but the cleanability is poor and residues accumulate in folded edges and welds
Solution Approach 1:
The patent replaces expensive aluminum containers with disposable plastic containers that are molded without folded edges or weld seams. This substitution eliminates the harmful factor of residue accumulation while maintaining ease of manufacture through injection molding processes. The plastic containers are designed to be single-use, eliminating cleaning requirements entirely.
Solution Approach 2:
The patent extracts and eliminates the problematic features of folded edges and weld seams from the container design. By using seamless plastic containers, the harmful factors of residue accumulation are completely removed, while the manufacturing process is simplified through mold-based production.
3Temperature
If aluminum containers are used for refrigeration devices, then good thermal conductivity is achieved, but the purchase price and manufacturing costs are high
Solution Approach 1:
The patent uses composite construction by combining plastic container material with aluminum adhesive tape applied to the outer surface. This composite structure provides the thermal conductivity of aluminum where needed for heat transfer, while maintaining the cost advantages and manufacturing simplicity of plastic containers. The aluminum tape is applied in a helical pattern during the winding process.
Solution Approach 2:
The patent replaces expensive aluminum containers with cheaper plastic containers designed for single use. The plastic containers eliminate the need for expensive aluminum material and complex welding processes, significantly reducing manufacturing costs while accepting the trade-off of single-use disposal rather than repeated cleaning and reuse.
4Manufacturing precision
If the rotary shaft is moved perpendicular to its axis of rotation, then the device for applying the tube maintains a constant angle to the container, but the mechanism complexity increases
Solution Approach 1:
The patent applies dynamics by implementing a rotary shaft with tiltable capability and perpendicular movement capability. These dynamic features allow the shaft to maintain optimal geometric relationships with the rotating container throughout the winding process, ensuring constant winding parameters. The increased device complexity is justified by the significant improvement in winding precision and speed.
