Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adhesive tape dispensers face challenges in achieving stability without excessive weight, which complicates mobility and safety, and existing solutions require specific surface conditions for attachment, limiting their versatility and ease of use.
Innovation Solution
A reversibly adhering adhesive pad with a first adhesive surface for the base and a second, smaller adhesive surface for external attachment, allowing secure placement on various surfaces without high intrinsic weight, and designed for easy detachment to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the dead weight of the adhesive tape dispenser is increased to improve stability during peeling and cutting, then the stability is improved, but the mobility and ease of transport deteriorate
Solution Approach 1:
The adhesive pad is divided into two distinct adhesive surfaces: a first adhesive surface with larger area for attachment to the dispenser base, and a second adhesive surface with smaller area for attachment to external surfaces. This segmentation allows the adhesive forces to be distributed differently, providing stability during operation while keeping the overall device lightweight.
Solution Approach 2:
The adhesive pad exhibits non-uniform adhesive properties through its two surfaces with different areas. The first adhesive surface has larger area to ensure strong attachment to the base, while the second adhesive surface has smaller area for controlled attachment to external surfaces. This local differentiation of adhesive characteristics resolves the contradiction between stability and weight.
2Stability of the object's composition
If the adhesive pad has large adhesive area for strong attachment, then the stability is improved, but the ease of detachment deteriorates
Solution Approach 1:
The adhesive pad is segmented into two adhesive surfaces with different areas. The second adhesive surface has a smaller area than the first adhesive surface, which reduces the total adhesive force between the pad and the external surface, making detachment easier while the first adhesive surface ensures strong attachment to the base.
Solution Approach 2:
The adhesive pad has differentiated local adhesive characteristics: the first adhesive surface with larger area provides strong attachment to the base, while the second adhesive surface with smaller area provides controlled attachment to external surfaces that is easy to detach. This local quality differentiation simultaneously achieves strong attachment and easy detachment.

AI summary
The dispenser has a standing surface (16), a cutting edge and a retainer for a roller of a rolled-up adhesive tape. A reversibly adhering adhesive pad (17) is formed at a surface of the standing surface. The adhesive pad has an adhesive surface for holding the adhesive pad to the standing surface and another adhesive surface for fixing the dispenser to an external surface, where the latter adhesive surface is smaller than the former adhesive surface. The latter adhesive surface partially covers the former adhesive surface in a direction normal to the standing surface.
