Multi-Roll Label Dispenser for Retail Carts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retail facility workers face inefficiency when attaching multiple types of labels to product packaging, as they need to frequently interchange and handle multiple label rolls, leading to a cumbersome process.
Innovation Solution
A multi-label roll dispenser system is designed to be coupled to a product-transporting cart, featuring a label roll support arm and guide arm that allows for easy mounting and efficient dispensing of labels from multiple rolls, with a support bar configuration that prevents the dispenser from sliding and rotating, facilitating the separation and detachment of labels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If workers use multiple separate label rolls on the cart, then different label types can be distributed, but the worker must frequently interchange and handle multiple label rolls which reduces efficiency
Solution Approach 1:
The patent combines multiple label rolls into a single integrated dispenser unit. The dispenser holds multiple label rolls simultaneously and allows the worker to switch between different label types without leaving the cart, thereby merging the function of multiple separate label rolls into one device that improves both versatility and efficiency.
Solution Approach 2:
The label dispenser is designed as a multi-functional device that can hold and dispense multiple different types of labels from a single unit. This universal design allows the worker to access various label types (e.g., fragile, heavy, refrigerated, frozen) from one dispenser rather than managing multiple separate rolls, thereby improving productivity while maintaining adaptability.
2Ease of operation
If the label dispenser is mounted on the cart, then labels can be dispensed at the point of use, but the dispenser may slide or rotate during use which affects stability
Solution Approach 1:
The mounting mechanism includes pre-designed anti-slip and anti-rotation features that are built into the dispenser structure before use. These features (such as friction surfaces and positioning elements) are already in place to prevent sliding and rotation, ensuring stability is maintained from the moment the dispenser is mounted on the cart.
Solution Approach 2:
The dispenser's mounting design allows it to self-stabilize on the cart through inherent friction and geometric constraints. The anti-slip and anti-rotation features are passive elements that automatically engage with the cart surface, requiring no active control or additional components to maintain stability during the labeling operation.

AI summary
A label dispenser coupled to product-transporting carts at retail facilities includes a label roll support arm supporting multiple label rolls thereon, a label guide arm including openings that permit a leading portion of the backing substrate of a label roll to pass therethrough, and a side wall interconnecting the label roll support arm and the label guide arm. The label guide arm also includes an upper portion located above the openings and configured to support the backing substrates of the label rolls thereon. The label guide arm further includes an edge configured to facilitate separation of a leading peelable label from the backing substrate in response to a force applied by the user when pulling the leading portion of the backing substrate of the label roll through the opening of the label guide arm.
