Rolled paper dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper dispensers often result in uncontrollable unrolling of paper rolls, leading to waste and inconvenience, especially due to free unrolling allowed by horizontal or vertical orientations without sufficient support.
Innovation Solution
A rolled paper dispenser with a diagonally oriented support member that includes a dispensing section angled from 25° to 65° and a securing section angled towards the base, providing frictional resistance to prevent accidental unrolling while allowing easy rotation and installation on a wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional horizontal or vertical dispensers are used, then installation is simple, but paper rolls unroll uncontrollably causing waste
Solution Approach 1:
The support member is oriented at a diagonal angle (25°-65°) relative to the wall surface, transitioning from conventional horizontal or vertical orientations. This angular orientation creates a geometric constraint that prevents the paper roll from unrolling freely while maintaining easy installation on the wall surface.
Solution Approach 2:
The securing section features a specific acute angle orientation that creates frictional resistance. By changing the angular parameter of the support member and securing section, the system achieves controlled resistance to unrolling without requiring complex mechanical fastening mechanisms.
2Loss of substance
If angled support member is used to prevent unrolling, then paper waste is reduced, but device complexity increases
Solution Approach 1:
The support member is divided into distinct functional sections: a dispensing section for supporting the paper roll and a securing section with an acute angle that creates frictional resistance. This segmentation allows each section to perform its specific function with simple geometry, avoiding the need for complex overall structure.
Solution Approach 2:
The angled geometry of the support member and securing section automatically provides frictional resistance to prevent unrolling. The structure serves itself by using its own angular configuration to create the necessary restraining force, eliminating the need for additional active control mechanisms or complex components.
3Ease of operation
If securing section with acute angle is used, then unrolling is limited, but installation difficulty increases
Solution Approach 1:
The support member features asymmetric geometry with the securing section oriented at an acute angle relative to the base. This asymmetric design creates the frictional resistance needed to control unrolling while maintaining a simple attachment interface with the wall, balancing control functionality with ease of installation.

AI summary
A rolled paper dispenser includes a base that has a rear surface, and a front surface. The rear surface is adapted to be mounted on wall. The rolled paper dispenser also includes a dispensing section that extends from the base at an angle away from the front surface of the base. The dispensing section is a generally elongated, flat, thin member and can include a securing section and an attachment section. The securing section extends from the dispensing section and defines an angle with the front surface of the base from about 25° to about 65°.
