Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sash designs for doors and windows face limitations in aesthetics, assembly time, costs, and thermal sealing, with existing modifications not fully addressing weight reduction, component rationalization, and adaptability to existing counterframes, while also struggling with edge coverage and appearance flexibility.
Innovation Solution
A sash design featuring a structural sealing component with a rigid profile and removable adhesion means, including a rigid plate for edge coverage, allowing for flexible appearance modification and easy adaptation to different frames, with a reduced component count and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional frame structure with uprights and crosspieces is used, then structural strength and stability are ensured, but assembly time increases and aesthetic quality deteriorates
Solution Approach 1:
The patent merges the frame structure with the double glazing unit by integrating the rigid profile directly into the peripheral zone of the glass assembly, eliminating the need for separate uprights and crosspieces. This integration reduces the number of components and simplifies assembly while maintaining structural strength through the continuous rigid profile that spans the entire perimeter.
Solution Approach 2:
The rigid profile is segmented into modular sections that can be independently assembled and then joined together to form the complete frame structure. This segmentation allows for pre-fabrication and simplified on-site assembly, reducing overall assembly time while maintaining structural integrity through standardized connection mechanisms.
2Strength
If a traditional frame structure with uprights and crosspieces is used, then structural strength is ensured, but aesthetic quality and thermal sealing deteriorate
Solution Approach 1:
The frame structure is merged with the double glazing unit's peripheral zone, creating a seamless integration where the rigid profile becomes an inherent part of the glass assembly rather than a separate aesthetic element. This merging eliminates visual discontinuities and creates a cleaner, more modern aesthetic while maintaining structural strength.
Solution Approach 2:
The rigid profile is strategically positioned and designed with varying cross-sections along different segments to optimize both aesthetic appearance and structural performance. The profile can be customized in terms of shape, size, and material finish to meet specific aesthetic requirements while maintaining the necessary structural strength at critical locations.
3Loss of time
If the frame structure is modified to reduce components, then assembly time and costs are reduced, but adaptability to existing counterframes deteriorates
Solution Approach 1:
The rigid profile incorporates adjustable and configurable features that allow it to adapt to different counterframe configurations. The profile can be modified in terms of mounting mechanisms, connection points, and dimensional parameters to accommodate various existing counterframe types, maintaining versatility despite the simplified component structure.
Solution Approach 2:
The rigid profile is designed as a universal component that can serve multiple functions: providing structural support, enabling attachment to various counterframes, facilitating thermal sealing, and supporting aesthetic requirements. This multi-functionality is achieved through standardized interface features and configurable design parameters that allow the same basic profile structure to work with diverse counterframe systems.
4Ease of manufacture
If glass edges are left exposed, then manufacturing simplicity is maintained, but aesthetic quality and edge protection deteriorate
Solution Approach 1:
The rigid profile is merged with the glass edge coverage function, where the profile itself serves as both the structural frame element and the edge covering component. This integration eliminates the need for separate edge treatment operations while providing aesthetic coverage and protection for the glass edges, maintaining manufacturing simplicity.
