Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing threshold systems for sliding and lift-slide doors face challenges in on-site adjustments due to differing installation conditions, leading to construction delays and issues with sealing different materials, which affect the tightness and reliability of the threshold.
Innovation Solution
A modular building connection profile system that allows for adjustable substructure frame extensions with uniform material surfaces, enabling on-site adaptation and improved sealability by connecting multiple modules with positive connections and shared fastening systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If frame extensions are prefabricated to fixed dimensions in the factory, then manufacturing precision is improved, but adaptability to different installation conditions deteriorates
Solution Approach 1:
The frame extension is divided into a base element and adjustable connection elements that can be segmented and reconfigured. The connection element can be positioned at different locations along the base element, allowing the overall length to be adjusted in discrete steps while maintaining factory precision in each component's manufacturing.
Solution Approach 2:
The frame extension transitions from a static fixed-dimensional component to a dynamic adjustable structure. The connection element can be repositioned along the base element to change the effective length, enabling adaptation to varying installation conditions while maintaining precise dimensional control through standardized positioning features.
2Adaptability or versatility
If adjustments are made on site based on re-measurement, then adaptability to installation conditions is improved, but construction time increases
Solution Approach 1:
Multiple possible adjustment positions are pre-configured into the frame extension design during manufacturing. The connection element includes pre-positioned attachment points or guide features that allow quick selection and adjustment on-site without requiring complex measurements or custom fabrication, reducing construction time while maintaining adaptability.
3Adaptability or versatility
If different material surfaces are used on the threshold, then functional requirements are met, but sealability deteriorates
Solution Approach 1:
A sealing element acts as an intermediary between different material surfaces of the threshold. This sealing component compensates for the incompatibility between different materials (such as aluminum and wood) by providing a continuous sealing interface that accommodates thermal expansion and contraction differences, ensuring reliable seal tightness across material joints.
4Manufacturing precision
If frame extensions are customized for each door element, then manufacturing precision for specific applications is improved, but device complexity increases
Solution Approach 1:
The frame extension is designed as a universal base element that can accommodate multiple door element types and dimensions. By using a standardized base with adjustable connection elements, the same fundamental component serves multiple functions and applications, reducing the number of unique custom parts needed while maintaining application-specific precision through adjustable positioning.
