Carrying Package Handle Adhesive Tab Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrier packaging blanks for transporting objects like bottles and cans require high structural and mechanical effort, along with excessive adhesive usage, making the manufacturing process costly and inefficient.
Innovation Solution
A blank design featuring separate adhesive tabs for connecting handle elements, allowing for reduced adhesive usage and incorporating handle reinforcement elements that can be placed on the inner side of the handle elements, enhancing stability and load-bearing capacity, while minimizing machinery requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If handle elements are glued together over large areas, then connection strength is improved, but manufacturing cost and adhesive usage increase significantly
Solution Approach 1:
The patent divides the adhesive bonding area into discrete segments: individual adhesive tabs on the first handle element and corresponding adhesive areas on the second handle element. This segmentation replaces large-area bonding with multiple small, localized bonding points, reducing adhesive consumption and simplifying the manufacturing process while maintaining adequate connection strength
Solution Approach 2:
The patent applies adhesive only at specific critical locations where bonding is most needed - namely at the adhesive tabs and their corresponding areas on the opposing handle element. This localized quality approach concentrates adhesive application where it provides maximum structural benefit, avoiding waste in areas where bonding is unnecessary
2Reliability
If large-area gluing of handle elements is used, then connection reliability is improved, but adhesive consumption increases
Solution Approach 1:
The bonding system is segmented into discrete adhesive tabs with defined areas, replacing continuous large-area bonding. Each tab creates a reliable localized bond, and the distribution of multiple tabs across the handle element ensures overall connection reliability while minimizing total adhesive quantity
Solution Approach 2:
The patent applies adhesive only partially - specifically at the tab areas rather than across the entire handle element surface. This partial action is sufficient to achieve reliable connection at the critical bonding points without the excess adhesive application that would be required for full-surface bonding
3Strength
If complex mechanical gluing structures are used, then connection strength is improved, but manufacturing complexity increases
Solution Approach 1:
The gluing structure is segmented into simple, discrete adhesive tabs with straightforward geometries rather than complex continuous bonding structures. Each tab is a simple feature that can be easily formed and positioned, reducing the overall mechanical complexity of the gluing system while maintaining effective connection
Solution Approach 2:
The adhesive tabs are integrated directly into the handle element structure, eliminating the need for separate complex gluing mechanisms or additional components. The tabs serve both as structural features and as the bonding interface themselves, simplifying the overall manufacturing system
