Linerless Tire Label Structure for Low-Waste, Low-Buildup Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire labels require a liner substrate to prevent adhesive buildup in printers, leading to waste generation and inefficient use of space due to the need for two substrates, which increases roll size and weight, and necessitates manual separation of the liner.
Innovation Solution
A linerless tire label design with high-tack adhesive patches on a single substrate, offset from the edges by adhesive-free gaps, and oversized sense marks for precise cutting, combined with a release coating on the front side to prevent adhesive buildup and enable direct printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a liner substrate is used to prevent adhesive buildup in printers, then adhesive buildup is minimized, but waste generation increases and roll size increases
Solution Approach 1:
The patent extracts and removes the liner substrate from the label structure, creating a linerless label that eliminates the source of waste while preventing adhesive buildup through alternative means (adhesive positioning and printer design modifications)
Solution Approach 2:
The patent eliminates the need to discard the liner substrate by removing it entirely from the system, transforming the waste management approach from disposal to elimination of the waste-generating component
2Object-generated harmful factors
If a liner substrate is used to prevent adhesive buildup, then adhesive buildup is minimized, but roll size and weight increase
Solution Approach 1:
The liner substrate is extracted and removed from the label structure, directly reducing the roll weight and size while maintaining adhesive buildup prevention through alternative design features
3Object-generated harmful factors
If two substrates (label and liner) are used, then adhesive buildup is prevented, but manufacturing complexity increases due to manual separation
Solution Approach 1:
The liner substrate is removed from the system, eliminating the manual separation step entirely and simplifying the application process while maintaining adhesive control through alternative means
Solution Approach 2:
The linerless label design allows the label to be directly applied to the tire without requiring manual intervention for liner removal, making the system self-sufficient and eliminating the manual operation step
4Object-generated harmful factors
If two substrates are used, then adhesive buildup is minimized, but productivity decreases due to fewer labels per roll
Solution Approach 1:
Removing the liner substrate increases the proportion of usable label material in the roll, allowing more labels to be manufactured and stored in the same roll size, directly improving productivity
Solution Approach 2:
The invention changes the structural parameters of the label system by eliminating the liner, which increases the effective label density in the roll and improves the number of labels that can be produced per roll
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
Reduces waste, eliminates manual liner removal, minimizes printer adhesive buildup, allows for smaller and lighter rolls with more labels, and lowers shipping costs by eliminating the need for a liner substrate.
Implementation Method 1
The frontside of the label substrate is coated with a release coating, such as a silicone-based release coating, ensuring that the backside of the label substrate when unwound from a roll by a printer releases from and does not stick to the frontside of the label substrate
Implementation Method 2
A high-tack adhesive, for example hotmelt rubber adhesive, is deposed as a patch on a backside of a label substrate
Data Source
AI summary
A linerless tire label and roll of linerless tire labels are provided. Each linerless tire label includes an adhesive patch disposed on a backside of a single label substrate. Gaps of adhesive-free areas surround the adhesive patch, and the gaps are adjacent to the sides of the backside label substrate. A front side of the label substrate has a print coating and a release coating disposed over the print coating. Each label on the roll is also separated by an oversized sense mark the extends the width of the backside of the label substrate. Each sense mark is also adjacent to a pair of adhesive-free gaps of the backside.
