Solution Overview

Problem

Existing adhesive paper dispensers face issues with inconsistent peeling performance, bending or deformation of adhesive paper during dispensing, and orientation variability due to reliance on friction-based mechanisms, leading to incomplete or unsuccessful dispensing.

Innovation Solution

The adhesive paper dispenser incorporates a turning peeling part and an adhesive paper guide part, with the guide part arranged upstream to direct adhesive paper to the peeling part, and includes limiting and bearing parts to maintain paper tension, along with a release paper guide part to facilitate smooth peeling and output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If friction-based mechanisms are used to drive strip material, then paper dispensing is achieved, but device complexity increases

Engineering Contradiction:
Improvepaper dispensingVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces friction-based mechanical driving systems with a tension-based mechanical system. Instead of using friction wheels and motors to drive the strip material, the invention uses a winding shaft that winds the release paper to create tension, which directly peels the adhesive paper from the release paper. This substitution eliminates complex friction-based mechanical components while achieving reliable paper dispensing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If strip material is pulled in different directions along the extension of the outlet, then peeling is achieved, but manufacturing precision deteriorates due to bending and deformation

Engineering Contradiction:
ImprovepeelingVSAvoidpaper orientation
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent introduces a turning peeling part with a curved surface that guides the release paper through a controlled bending path. This curved guiding surface ensures the paper follows a precise trajectory during peeling, preventing random bending and deformation. The curvature of the turning peeling part maintains paper orientation consistency while enabling effective peeling action.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Productivity

If friction-based driving is used, then paper conveyance is achieved, but reliability decreases due to inconsistent peeling performance

Engineering Contradiction:
Improvepaper conveyanceVSAvoidpeeling performance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent extracts the adhesive paper from the release paper through a dedicated turning peeling part that applies localized peeling action. By separating the peeling function from the conveyance function, the system ensures reliable peeling performance. The winding shaft continuously supplies tension to maintain consistent peeling, while the turning peeling part provides a dedicated pathway for adhesive paper output, ensuring high reliability.

Inventive Principle:
Principle #2Taking out (Extraction)
