Heat-Insulating Wing Post for Sliding Frame Thermal Break
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wing posts for sliding frame devices lack adequate thermal insulation, leading to undesirable heat transfer between the outside and inside, especially when there are large temperature differences.
Innovation Solution
The wing post is made entirely of a heat-insulating material, such as plastic, with integrated receiving areas for surface element holders and a center seal, eliminating the need for metal parts that could facilitate heat conduction, and optionally incorporating additional seals for enhanced sealing and insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional metal wing posts are used for structural strength, then load-bearing capacity is improved, but thermal insulation deteriorates due to heat conduction along the metal posts
Solution Approach 1:
The patent removes metal components from the thermal transmission path by extracting only the necessary functional elements (sealing elements, receiving areas) and implementing them in a heat-insulating material, thereby eliminating the harmful heat conduction while preserving structural function
Solution Approach 2:
The wing post is constructed as a composite structure where the primary load-bearing and thermal insulation functions are integrated into a single heat-insulating material component, combining structural integrity with thermal protection without relying on metal
2Loss of energy
If the entire wing post is made of heat-insulating material, then thermal insulation is improved, but load-bearing capacity may deteriorate
Solution Approach 1:
The patent changes the material parameter from metal to heat-insulating material for the entire wing post, and compensates for potential strength deficiencies by optimizing the geometric parameters and structural design of the heat-insulating component to maintain adequate load-bearing capacity
3Ease of manufacture
If metal parts are used for surface element holders, then ease of manufacture is improved, but thermal insulation deteriorates due to additional heat conduction paths
Solution Approach 1:
The patent extracts metal parts from the surface element holder assembly and replaces them with heat-insulating material components, eliminating additional heat conduction paths while maintaining the holding function through appropriately designed receiving areas in the heat-insulating wing post

AI summary
The post (101) has receiving areas (105, 106) for receiving surface element supports (120, 121), where the post is produced from a heat insulating material e.g. sustainable plastic such as PVC. The surface element supports support a surface element (102) i.e. glazing, from different opposite sides, where the post is integrally formed together with a middle closing seal (103) and a middle closing seal-counter element (104). An additional seal (107) forms a sealing end with a counter leaf (200) in a closed position of a leaf (100) relative to the counter leaf.
