Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing covering devices for high-temperature coating processes lack thermal resistance and dimensional stability, leading to potential damage to components and limited reusability, especially when temperatures exceed 220°C, and are not suitable for extended high-temperature applications.
Innovation Solution
A covering device fabricated from high-temperature-resistant plastic with integrated fibers that maintains dimensional stability up to 1000°C, allowing form-fitting placement on components without causing damage and enabling multiple uses, while being lighter and less prone to deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If covering devices are made of steel for high-temperature coating processes, then thermal resistance is improved, but the component surface may be damaged and dimensional stability is poor
Solution Approach 1:
The patent changes the material parameter from traditional steel to a specifically formulated plastic composite that maintains dimensional stability at high temperatures (up to 1000°C). This parameter change allows the covering device to resist thermal deformation while being gentler on the component surface, eliminating the trade-off between thermal resistance and surface protection.
Solution Approach 2:
The patent employs a composite material structure consisting of plastic base material reinforced with temperature-stable fibers. This composite approach combines the benefits of plastic (surface protection, dimensional stability) with the thermal resistance previously only achievable through steel, resolving the contradiction between material hardness and surface gentleness at high temperatures.
2Temperature
If covering devices are made of steel for high-temperature coating processes, then thermal resistance is improved, but device weight increases and handling becomes more difficult
Solution Approach 1:
The patent changes the density parameter of the covering device material from steel to plastic composite, significantly reducing weight while maintaining thermal resistance through the fiber reinforcement. This allows the device to remain lightweight and easy to handle even at temperatures up to 1000°C, eliminating the weight penalty associated with steel construction.
3Ease of operation
If silicone-containing masking elements are used for coating processes, then ease of placement and removal is improved, but thermal resistance is insufficient for temperatures above 220°C
Solution Approach 1:
The patent develops a plastic composite material that combines the flexibility and ease of handling characteristic of silicone materials with the high-temperature resistance previously unavailable in such materials. The fiber-reinforced plastic structure maintains dimensional stability at temperatures up to 1000°C while retaining sufficient flexibility for easy placement and removal, eliminating the 220°C temperature limit of silicone-based solutions.
