Cluster Pack Container Wall Reinforcement for Adhesive Joint Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generic containers connected by adhesive points, especially when connected in the lower half, tend to tear due to leverage effects, as they lack sufficient reinforcement to resist detachment forces.
Innovation Solution
The container walls are reinforced in the splice region or adjacent areas with a thicker section, providing increased resistance to detachment forces, and the reinforcement can be applied locally or uniformly, with a diameter at least 3% larger than the adhesive point, to prevent tearing and minimize material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If containers are connected by adhesive points in the lower half, then the pack structure is formed, but the container wall tears due to leverage effects
Solution Approach 1:
The patent applies a ring reinforcement element specifically at the splice location where the adhesive point is applied, creating a localized strengthening zone. This ring reinforcement increases the wall thickness or structural integrity only at the critical stress point, allowing the container to withstand the leverage effects during detachment while maintaining normal wall thickness elsewhere.
2Strength
If the container wall is made thicker to prevent tearing, then the strength increases, but the material usage increases
Solution Approach 1:
Instead of uniformly thickening the entire container wall, the patent implements a localized ring reinforcement only at the splice location. This targeted approach provides the necessary strength to prevent tearing during detachment while minimizing additional material consumption, as the reinforcement is confined to a specific circumferential zone rather than the entire container surface.
3Strength
If a ring reinforcement is added to the container wall, then the resistance to detachment forces increases, but the device complexity increases
Solution Approach 1:
The ring reinforcement can be implemented by varying the wall thickness parameter locally or by applying a separate reinforcement layer with different material properties. This parameter change approach allows the reinforcement to be integrated into existing container manufacturing processes without fundamentally altering the container design or requiring complex additional components.
