Door Decor Unit Sealing Without Strips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing doors with glass decor units face challenges in accommodating different geometric designs, requiring complex tolerance adjustments and the use of strips for sealing and security, which complicates the manufacturing process and compromises aesthetics.
Innovation Solution
A door design where a decor unit is placed between two outer layers, with the decor unit having a larger area than the opening, eliminating the need for strips and allowing for various geometric designs by forming openings in the outer layers separately, using inner layers for sealing and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strip is used to attach the unit of glass to the door, then the unit of glass can be secured and sealed, but the aesthetics are compromised and the manufacturing process becomes more complicated
Solution Approach 1:
The patent removes the strip attachment element from the door assembly, extracting the problematic component that compromised aesthetics and complicated manufacturing. The glass unit is instead secured through the layer structure itself, eliminating the need for visible strips and simplifying the manufacturing process.
Solution Approach 2:
The patent introduces inner layers as intermediary elements between the outer layers and the glass unit. These inner layers serve as sealing and securing elements, replacing the need for external strips while maintaining the required functionality of sealing and securing the glass unit.
2Ease of manufacture
If the opening in the door is made to match the geometry of the unit of glass, then the glass unit can be properly installed, but tolerance adjustment becomes necessary during assembly
Solution Approach 1:
The patent divides the door structure into multiple layers (first outer layer, inner layers, second outer layer) with separate openings. This segmentation allows each layer to have its opening independently formed, eliminating the need for precise tolerance matching between layers while still achieving proper glass unit installation.
Solution Approach 2:
The patent creates a universal opening structure where the inner layers provide a standardized sealing interface that works with glass units of different geometries. The inner layers serve multiple functions: sealing, securing, and accommodating various glass unit shapes without requiring custom tolerance adjustments for each case.
3Object-affected harmful factors
If a strip is used to seal and secure the unit of glass, then water and wind penetration is prevented, but the strip must be precisely adjusted which complicates the process
Solution Approach 1:
The patent extracts the sealing function from the strip attachment element and relocates it to the inner layers. This separation eliminates the need for complex strip adjustments while maintaining effective sealing against water and wind penetration.
Solution Approach 2:
The inner layers act as intermediary sealing elements between the outer layers and the glass unit, providing a built-in sealing mechanism that eliminates the need for separate adjustment-prone strips. The inner layers are integrated into the door structure, providing consistent sealing without requiring precise field adjustments.
