Adhesive-Patch Roll Holder for Thin or Temporary Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted toilet paper holders are not feasible for temporary or thin surfaces, such as those found in tents or homeless shelters, as they require drilling or heavy hardware, making them impractical for portable or lightweight installations.
Innovation Solution
A holder assembly using cordage inserted through the roll's core, forming legs that are secured to a thin adhesive patch, allowing suspension on various surfaces without the need for drilling or heavy hardware, with options for knotting, fusion, or sewing the cordage to the patch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drilling or heavy hardware is used for wall-mounted holders, then the holder can support the roll securely, but it becomes impractical for thin or temporary surfaces
Solution Approach 1:
The patent replaces the mechanical drilling and heavy hardware system with an adhesive-based suspension system. The holder uses adhesive patches applied to the wall surface to attach lightweight cordage, which then suspends the toilet paper roll. This substitution eliminates the need for drilling while maintaining sufficient support capability through proper adhesive selection and cordage tensioning.
Solution Approach 2:
The patent employs thin adhesive film patches as the mounting mechanism. These flexible adhesive films can conform to various wall surfaces including thin or temporary structures without requiring penetration or heavy anchoring. The thin film nature allows application to surfaces that cannot support drilling or heavy hardware while providing reliable attachment.
2Reliability
If a pulley holder is used, then the toilet paper can be suspended, but it requires adhesive curing for 72 hours and heat application
Solution Approach 1:
The patent employs disposable-style adhesive patches that provide immediate or rapid attachment without requiring long curing periods. These adhesive patches are designed for quick installation and immediate use, sacrificing the longevity and reusability of permanent mounting systems like pulleys in exchange for rapid deployment. The adhesive patches can be easily replaced if needed, making the system suitable for temporary or mobile applications.
3Ease of operation
If a stand-alone device is used, then it provides holder functionality, but it is burdensome to carry
Solution Approach 1:
The patent divides the holder system into separate functional components: adhesive patches for mounting, lightweight cordage for suspension, and the toilet paper roll itself. This segmentation allows each component to be minimal in weight and size, enabling the entire system to be carried easily in a backpack or bag. The modular nature also allows for flexible installation at the destination without requiring transport of a complete pre-assembled unit.

AI summary
A holder for a roll of toilet paper or a roll of absorbent sheet material, the roll having a hollow cylindrical core, the holder comprising a patch formed of paper, cloth or thin plastic sheet, having an adhesive surface, cordage for insertion through the core secured to the patch. The assembly of the patch and cordage is capable of suspending the roil by adhesion of the patch to a surface. The cordage forms two legs which can be secured to the patch. Alternatively, one end of one leg of the cordage is fixed at a distal point below the patch to the other leg, the end of which is secured to the patch. The adhesive can be covered by a release sheet.
