Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glazed wall assembly methods, such as silicone and double-sided adhesive joints, are difficult to assemble and disassemble, require precision, and complicate panel replacement or reconfiguration, while also being aesthetically challenging and not easily reversible.
Innovation Solution
A connecting joint system with adjustable force of separation, featuring a layer of adhesive or mechanical anchoring means, allowing for easy assembly and disassembly of glazed wall panels while maintaining a transparent appearance, utilizing a differential adhesive system with varying peeling forces to ensure cohesion and ease of panel repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a silicone seal is used to assemble panel edges, then the aesthetic appearance is preserved with a small section, but the assembly and disassembly become difficult and require removing the seal and cleaning edges
Solution Approach 1:
The connecting joint is divided into multiple functional layers: a first adhesive layer for bonding to the first panel, a second adhesive layer for bonding to the second panel, and an intermediate layer providing mechanical properties. This segmentation allows each layer to be optimized for its specific function, enabling both aesthetic appearance and ease of assembly/disassembly.
Solution Approach 2:
The patent specifies precise parameter ranges for the adhesive layers, including shear modulus (10^5 to 10^7 Pa for the first layer, 10^6 to 10^8 Pa for the second layer) and thickness (0.1 to 5 mm for the first layer, 0.05 to 2 mm for the second layer). These parameter changes enable the joint to achieve both strong bonding for aesthetics and controlled detachment for ease of operation.
2Shape
If a double-sided adhesive joint is used to assemble panel edges, then the aesthetic appearance is preserved with a small section, but the bonding requires particular care for vertical alignment and disassembly is difficult requiring peeling off the adhesive
Solution Approach 1:
The intermediate layer between the two adhesive layers provides dynamic mechanical properties that allow the joint to accommodate alignment variations during assembly. The specific shear modulus range (10^6 to 10^8 Pa) enables the layer to deform and adapt to minor misalignments while maintaining bond strength, reducing the need for precise alignment during manufacturing.
3Strength
If a strong adhesive bond is used to firmly connect panels, then the cohesion of the glazed wall is ensured, but the disassembly and panel replacement become difficult
Solution Approach 1:
Different adhesive layers are assigned different local qualities: the first adhesive layer has lower shear modulus (10^5 to 10^7 Pa) and greater thickness (0.1 to 5 mm) for easier detachment, while the second adhesive layer has higher shear modulus (10^6 to 10^8 Pa) and smaller thickness (0.05 to 2 mm) for stronger bonding. This local quality differentiation enables strong overall cohesion while allowing controlled disassembly through the first layer.
4Adaptability or versatility
If the connecting joint allows easy disassembly for panel repositioning, then the adaptability is improved, but the connection strength may be compromised
Solution Approach 1:
The connecting joint uses a composite structure with multiple adhesive layers having different mechanical properties. The first adhesive layer (shear modulus 10^5 to 10^7 Pa, thickness 0.1 to 5 mm) provides easy detachment for repositioning, while the second adhesive layer (shear modulus 10^6 to 10^8 Pa, thickness 0.05 to 2 mm) ensures strong connection strength. This composite approach simultaneously achieves adaptability and strength.

AI summary
This connecting joint (6) between two panels (2, 2') of a glazed wall is intended to cooperate with one face (23, 21') of each panel (2, 2') and has: at least one mounting (7) having a first outer face (7A) and a second outer face (7B); a first securing means (8) located on the first outer face (7A) of the mounting; a second securing means (9) located on the second outer face (7B) of the mounting. The detachment force at right angles of the first securing means (8), measured on a glass panel using a tensile test machine having a movable jaw, is between 3 and 20 N/cm for a speed of movement of the movable jaw of 100 mm/min, while the detachment force at right angles of the second securing means (9), measured on a glass panel using a tensile test machine having a movable jaw, is greater than or equal to 30 N/cm for a speed of movement of the movable jaw of 100 mm/min.
