Use of a tacky mat for securing a portable roll dispenser to a horizontal surface and portable roll dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable roll dispensers for sheet materials face challenges with one-handed operation, adhesive residue issues, and reduced adhesion over time, particularly on rough surfaces, due to the limitations of current attachment methods such as double-sided tapes and suction cups.
Innovation Solution
A tacky mat made from a tacky elastomeric polymer composition is used to securely attach a portable roll dispenser to various surfaces, featuring a smooth side for the dispenser and a textured side for adhesion, which maintains strong adhesive forces without leaving residue and remains effective over repeated use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If double-sided adhesive tapes with sufficiently strong adhesive force are used to secure the dispenser to a surface, then the dispenser can be firmly attached, but adhesive residues are left on the surface when removed
Solution Approach 1:
The patent changes the chemical and physical parameters of the adhesive material from traditional permanent adhesives to a reversible adhesive composition. This composition allows strong initial bonding but enables clean removal without residues through controlled chemical reversibility or physical phase changes, resolving the contradiction between strong attachment and clean removal.
Solution Approach 2:
The patent employs a composite adhesive material that combines multiple functional components: a base adhesive polymer, reversible bonding agents, and surface-active compounds. This composite structure provides both strong initial adhesion and controlled reversibility, allowing the dispenser to be firmly attached and then cleanly removed without leaving residues on the surface.
2Object-generated harmful factors
If adhesive force is adjusted to be smaller to avoid adhesive residues, then clean removal is achieved, but the dispenser cannot be securely held or drops after repeated use
Solution Approach 1:
The patent utilizes parameter changes in the adhesive composition to achieve time-dependent or condition-dependent adhesion strength. The adhesive maintains strong bonding under normal conditions and repeated use, but allows for controlled reduction of adhesion strength during removal operations, ensuring both reliable holding and clean removal without residues.
Solution Approach 2:
The adhesive system operates in periodic cycles of strong bonding during use and controlled weakening during removal. This periodic modulation of adhesive properties allows the dispenser to be securely held during normal operation while enabling clean, residue-free removal when needed, resolving the contradiction between holding strength and clean removal.
3Strength
If adhesive polymers are used to secure the dispenser, then initial adhesion is achieved, but they are easily soiled with dust, grease or other dirt which drastically reduces their adhesive effect
Solution Approach 1:
The patent extracts and removes the vulnerable adhesive polymer layer from direct contact with the external environment. By positioning the adhesive between the dispenser base and the mounting surface, shielded from direct exposure to dust and grease, the adhesive effect is protected from degradation while maintaining strong bonding capability.
Solution Approach 2:
The adhesive composition acts as an intermediary layer that protects the bonding interface from contamination. The reversible adhesive formulation includes components that resist soiling with dust and grease, maintaining adhesive effectiveness even in challenging environmental conditions, thus resolving the contradiction between adhesion strength and resistance to soiling.
4Ease of operation
If a portable dispenser is made soft and flexible for portability, then it can be carried around, but it tilts over or moves when sheet material is pulled and torn
Solution Approach 1:
The patent applies dynamic principles by making the dispenser base adaptable in its mechanical properties. The base can be slightly flexible during handling for portability but becomes stable during dispensing through the friction-enhancement device that provides anchoring to the surface, resolving the contradiction between ease of carrying and stability during operation.
Solution Approach 2:
The friction-enhancement device acts as an intermediary between the soft dispenser base and the mounting surface. This device provides the necessary mechanical anchoring and stability during dispensing operations while allowing the base to remain soft and flexible for portability, thus resolving the contradiction between ease of operation and stability.
