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

VSEngineering 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

Engineering Contradiction:
Improvestorage simplicityVSAvoiddurability
Core Design Contradiction:
Ease of manufactureVSReliability

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If frequent handling is allowed, then ease of operation is improved, but durability and resistance deteriorate

Engineering Contradiction:
Improveease of extractionVSAvoidresistance to handling
Core Design Contradiction:
Ease of operationVSReliability

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #25Self-service

3Device complexity

If manual separation of pads from strip is used, then device complexity is reduced, but productivity and efficiency deteriorate

Engineering Contradiction:
Improvestructure simplicityVSAvoiddispensing efficiency
Core Design Contradiction:
Device complexityVSProductivity

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Device complexity

If excess strip is not cut, then device complexity is reduced, but loss of substance increases

Engineering Contradiction:
Improvecutting mechanism complexityVSAvoidexcess strip waste
Core Design Contradiction:
Device complexityVSLoss of substance

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.

Inventive Principle:
Principle #25Self-service

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.
