Sliding Profile Insulating Web for Thermal Stress Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Components such as doors and windows experience stress due to differential thermal expansion of inner and outer shell parts, leading to deformation and sealing issues, which existing solutions often fail to adequately address effectively.
Innovation Solution
Incorporating a sliding profile and insulating web with receiving chambers for fittings, where the insulating web is firmly connected to the inner shell part and the sliding profile is on the outer shell part, allowing for thermal expansion compensation without stress, and featuring a guide profile with profile projections for sealing and displacement compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the inner and outer shell parts are rigidly connected, then structural stability is improved, but thermal stress-induced deformation increases
Solution Approach 1:
The patent applies the dynamics principle by introducing a sliding profile mechanism that allows the outer shell part to move relative to the inner shell part. This dynamic connection enables the structure to adapt to thermal expansion and contraction, preventing rigid stress accumulation while maintaining overall structural stability. The sliding profile transforms the rigid connection into a controlled movable joint that accommodates dimensional changes.
Solution Approach 2:
The patent employs parameter changes by modifying the connection state between shell parts from fixed to movable. The sliding profile changes the mechanical parameters of the connection, allowing relative displacement while maintaining structural integrity. This parameter transformation enables the structure to handle thermal stress without deformation.
2Strength
If the outer shell part is firmly fixed to the inner shell part, then structural rigidity is improved, but sealing performance deteriorates
Solution Approach 1:
The sliding profile creates a dynamic connection that maintains structural rigidity while allowing controlled movement for sealing. The guide profile with groove pockets provides guided movement that preserves the sealing relationship between the outer shell part and the insulating web, preventing leakage while accommodating thermal expansion.
Solution Approach 2:
The insulating web acts as an intermediary element between the inner and outer shell parts. It provides both thermal insulation and a sealing function, while the sliding profile mechanism mediates the connection, allowing relative movement without compromising the sealing integrity. The guide profile and groove pockets work together as an intermediary mechanism to maintain sealing during movement.
3Shape
If complex measures are taken to eliminate thermal stresses, then deformation is reduced, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the connection system into distinct functional elements: the sliding profile for movement, the guide profile for guidance, and the groove pockets for positioning. This segmentation allows each element to perform its specific function efficiently, reducing overall complexity while effectively eliminating thermal stress-induced deformation.
Solution Approach 2:
The patent uses parameter changes by transforming the connection from rigid to movable through the sliding profile mechanism. This single parameter change (from fixed to sliding connection) achieves deformation reduction without requiring multiple complex measures, thereby maintaining simplicity in the overall device design.
