Pivot Door Sealing Structure for Rain and Thermal Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pivot doors, particularly in older buildings, face challenges with maintaining long-term operational reliability and effective sealing against environmental influences due to their large size and lack of conventional fittings, leading to issues like driving rain ingress and thermal energy transfer.
Innovation Solution
A multi-part sealing system comprising a first and second base body, a rotary bearing, and movable seals, including a magnetic strip and flexible lip, which creates a thermal barrier and protects the pivot bearing from environmental elements while allowing easy installation and drainage, suitable for both new and old buildings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pivot door is used in older buildings, then the door can provide large opening angles and modern aesthetics, but the sealing system becomes vulnerable to driving rain ingress and thermal energy transfer
Solution Approach 1:
The sealing system is divided into multiple base bodies (first base body, second base body) with separate sealing functions. The first base body provides structural support while the second base body houses the rotary bearing, allowing independent optimization of each component's sealing performance against driving rain.
Solution Approach 2:
A separating element with lower thermal heat transfer coefficient is introduced between the first and second base bodies. This intermediary component specifically addresses thermal energy transfer while maintaining the mechanical coupling needed for door operation, thereby reducing heat loss without compromising the sealing against rain.
2Reliability
If a pivot door is used in older buildings, then the door can provide large opening angles and modern aesthetics, but thermal energy transfer between interior and exterior increases
Solution Approach 1:
A separating element with lower thermal heat transfer coefficient is introduced between the first and second base bodies. This intermediary component specifically addresses thermal energy transfer while maintaining the mechanical coupling needed for door operation, thereby reducing heat loss without compromising the sealing against rain.
Solution Approach 2:
The sealing system employs different materials with varying thermal properties in its base bodies and separating elements. By combining materials with appropriate thermal characteristics, the system achieves both mechanical durability for long-term operation and thermal insulation to minimize energy transfer between interior and exterior environments.
3Ease of manufacture
If a multi-part sealing system is used, then the system can be easily installed and adapted to different building situations, but the device complexity increases
Solution Approach 1:
The sealing system is divided into multiple base bodies (first base body, second base body) with separate sealing functions. The first base body provides structural support while the second base body houses the rotary bearing, allowing independent optimization of each component's sealing performance against driving rain.
