Label With Tapered End And Localized Adhesive For Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic labelling machines often apply labels incorrectly, leading to misalignment, reduced aesthetic appeal, and increased waste, particularly when labelling delicate products like flowers, resulting in production delays and environmental issues.
Innovation Solution
A label with a tapered end and rectangular second end, featuring adhesive applied in a triangular shape and longitudinal strip, ensures secure alignment and display, even with imperfect alignment, using a hot melt adhesive and silicon varnish to prevent adhesive contact with the product and facilitate easy reapplication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is applied to the entire label surface, then the label adheres strongly to the product, but the adhesive contacts the delicate product causing damage
Solution Approach 1:
The patent applies adhesive only to specific regions (margins or borders) of the label rather than the entire surface. This localized adhesive application ensures strong bonding at the edges while preventing adhesive contact with the delicate flower product in the central area, thus resolving the contradiction between adhesion strength and product safety.
2Productivity
If the label is applied quickly for high throughput, then production efficiency increases, but label orientation accuracy decreases
Solution Approach 1:
The patent employs asymmetric design elements such as a tapered end and directional adhesive placement (e.g., adhesive only on the leading margin or specific bordered regions). This asymmetry creates a clear orientation reference that guides automatic labelling machines to apply labels in the correct direction, maintaining high precision even at high speeds.
Solution Approach 2:
The label's asymmetric features (tapered end, directional adhesive zones) are pre-configured during manufacturing to provide built-in alignment guidance. This preliminary design enables automatic machines to quickly and accurately orient labels without requiring complex adjustment or slow manual positioning, thus achieving both high throughput and high precision.
3Productivity
If misaligned labels are used, then production continues without interruption, but aesthetic appeal and product security decrease
Solution Approach 1:
The patent incorporates a tolerance buffer through its asymmetric design, particularly the tapered end and strategic adhesive placement. This design cushioning allows for some degree of misalignment without compromising the label's securing function or aesthetic appearance, effectively absorbing alignment errors and maintaining reliability even when production speed causes minor positioning variations.
4Device complexity
If single-use labels are used, then labelling simplicity is maintained, but waste increases when labels are misapplied
Solution Approach 1:
By concentrating adhesive in specific localized regions (margins or borders) rather than across the entire label, the patent enables more precise and controlled application. This reduces the penalty for misalignment and allows for potential repositioning or correction, thereby reducing waste from discarded misapplied labels while maintaining system simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The label ensures accurate and efficient labelling, reduces waste, and maintains aesthetic appeal by allowing correct alignment and easy reapplication, thereby minimizing production downtime and environmental impact.
Implementation Method 1
adhesive applied to the first end and to the second end of the label

AI summary
A label (30) for securing a bunch of elongate products, wherein the label (30) is substantially rectangular comprising two discrete adhesive areas (38, 39), such that when the label (30) is wrapped around the elongate products the two adhesive areas (38, 39) meet to secure the label (30) in a loop having an adhesive-free area (32) forming the loop around the elongate products and a flat section protruding therefrom.
