Dispenser With Automatic Strip Separation And Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-adhesive dot rolls lack durability due to lack of storage support and frequent handling, leading to deterioration and poor resistance.
Innovation Solution
A device with a housing that includes outer and inner strip guides for easy extraction and automatic separation of self-adhesive dots, along with a cutting mechanism to remove excess strip, and a lockable side cover for the roll, allowing for efficient dispensing and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If self-adhesive dot rolls are stored without proper support, then storage simplicity is improved, but durability and resistance deteriorate
Solution Approach 1:
The dispenser is divided into modular components: a housing structure, a roll holder for the self-adhesive dot roll, external band guides for strip guidance, and a cutting mechanism. This segmentation allows each component to perform its specific function while contributing to overall durability without complicating storage.
Solution Approach 2:
The patent introduces intermediary elements such as the external band guides and cutting blade that mediate between the roll and the user. These intermediaries protect the roll during handling and storage while enabling easy extraction and cutting of the strip, thus improving both durability and ease of use.
2Ease of operation
If frequent handling is allowed, then ease of operation is improved, but durability and resistance deteriorate
Solution Approach 1:
The external band guides are pre-positioned to guide the strip along a predetermined path before the user extracts it. The cutting blade is pre-positioned to automatically cut the strip at the correct location. These preliminary arrangements make extraction easy while protecting the roll from excessive handling.
Solution Approach 2:
The dispenser is designed to perform cutting and guiding functions automatically without requiring user intervention. The strip is automatically guided through the external band guides and cut by the blade, reducing the need for frequent manual handling and thus improving durability while maintaining ease of operation.
3Device complexity
If manual separation of pads from strip is used, then device complexity is reduced, but productivity and efficiency deteriorate
Solution Approach 1:
The external band guides act as intermediaries that automatically separate the pads from the strip as the strip passes through them. This automatic separation mechanism adds minimal structural complexity while significantly improving dispensing efficiency by eliminating manual separation steps.
4Device complexity
If excess strip is not cut, then device complexity is reduced, but loss of substance increases
Solution Approach 1:
The cutting blade is positioned to automatically cut the strip at the correct location as it passes through the external band guides. This self-service cutting function eliminates excess strip waste without requiring complex control mechanisms, achieving a balance between device simplicity and material efficiency.

AI summary
The present invention relates to a dispenser for storing and dispensing self-adhesive stickers/labels. It comprises a body (1) including a strip outlet (4), an inner guide (7), an upper guide (8) that constrains the strip to fold it and allows automatic separation of the sticker/label by pulling (10) on the strip (5), and a final guide (11) including a cutting blade (12). The device according to the invention is particularly intended for use with rolls of self-adhesive stickers/labels.
