Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper or cardboard blanks for producing bottle-like objects face challenges in automated production due to complex mechanical requirements and often result in leaks at the bottle neck area.
Innovation Solution
A blank design featuring a sequence of differently configured neck tabs with overlapping adhesive sections, allowing for simple machine-based production and improved tightness, achieved by integrating crease lines and varying tab lengths for enhanced stability and formability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional neck tab designs are used, then bottle neck formation is achieved, but automated production becomes complex and mechanical effort increases
Solution Approach 1:
The neck tab is divided into multiple segments (first neck tab, second neck tab, third neck tab) with different configurations. Each segment serves a specific function in the assembly process, allowing automated machines to handle each segment separately and simplify the overall production process.
Solution Approach 2:
Different regions of the neck tab have different properties - the first neck tab has a first configuration optimized for initial assembly, the second neck tab has a second configuration optimized for intermediate assembly, and the third neck tab has a third configuration optimized for final assembly. This local differentiation enables specialized automated handling for each region.
2Reliability
If traditional neck tab designs are used, then bottle neck formation is achieved, but leaks develop in the bottle neck area
Solution Approach 1:
The neck tab is segmented into multiple tabs with different configurations that assemble in sequence. Each segment provides a specific bonding interface, and the cumulative effect of these segmented bonds creates a leak-proof seal while maintaining manufacturing simplicity through standardized assembly steps.
Solution Approach 2:
The neck tabs have asymmetric configurations where each tab is differently shaped or oriented compared to the others. This asymmetry ensures proper alignment and bonding orientation during assembly, preventing leaks by ensuring that each tab bonds correctly to its counterpart while maintaining ease of manufacture through clear assembly directions.
3Ease of manufacture
If multiple identically formed neck tabs are used, then production is simplified, but bonding strength and tightness are insufficient
Solution Approach 1:
Each neck tab region has locally optimized properties - the first neck tab has a first configuration optimized for initial bonding, the second neck tab has a second configuration optimized for intermediate bonding, and the third neck tab has a third configuration optimized for final bonding. This local quality differentiation ensures strong bonding at each stage while maintaining overall production simplicity.
Solution Approach 2:
The neck tabs are designed to be dynamically assembled in sequence rather than all at once. The first neck tab bonds to the body portion, then the second neck tab bonds to the first, and finally the third neck tab bonds to the second. This dynamic sequential assembly builds bonding strength progressively while keeping the manufacturing process simple and controlled.
