Toilet Roll Core Wipe Container for Capacity and Moisture Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The disposable wipe industry has struggled to gain market share against toilet paper due to limited storage space and frequent refilling in existing solutions that attempt to integrate wet wipes into toilet paper roll holders, often compromising convenience and moisture retention.
Innovation Solution
A toilet paper roll holder design with a multi-axis arrangement that includes an elongated container body for increased wipe storage, secured by connectors and a bias member, allowing offset installation to fit within traditional mounting brackets and providing a sealed environment for moisture retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wet wipes are stored within the core of the toilet paper roll, then the wipes are placed in a convenient location, but the storage space for wet wipes is extremely limited
Solution Approach 1:
The patent applies nesting by placing the container body inside the hollow interior of the toilet paper roll, allowing the wipe storage system to be nested within the existing toilet paper structure. This enables convenient access while maximizing the use of available space within the roll's hollow core.
Solution Approach 2:
The patent transitions from two-dimensional storage (flat wipes in core) to three-dimensional storage by implementing a container body with depth, allowing wipes to be stacked vertically and horizontally within the container's interior volume, significantly increasing storage capacity.
2Reliability
If mechanical features such as spring are placed inside the core of the toilet paper roll, then the device functionality is enabled, but the wet wipe storage space is further limited
Solution Approach 1:
The patent segments the device into distinct functional components: the container body for storage, the spring mechanism for dispensing, and the cap for sealing. This segmentation allows the mechanical spring to be positioned outside the hollow interior of the roll, preventing it from encroaching on the storage space while maintaining full functionality.
Solution Approach 2:
The patent extracts the spring and other mechanical features from the hollow interior of the toilet paper roll and positions them on the exterior or in dedicated mechanical compartments. This extraction frees up maximum space within the hollow core for wipe storage while preserving all necessary device functions.
3Ease of operation
If an opening is provided on the end of the device for dispensing of wet wipes, then access to wipes is enabled, but moisture loss from stored wipes occurs
Solution Approach 1:
The patent employs a cap that seals the opening of the container body, creating a flexible barrier that prevents moisture loss while allowing the container to remain accessible. The cap can be opened for dispensing and closed for moisture retention, balancing access needs with moisture preservation.
Solution Approach 2:
The patent creates a sealed environment within the container body that protects the wet wipes from external air exposure, maintaining a moisture-rich atmosphere inside the container and preventing evaporation and drying of the stored wipes.
4Adaptability or versatility
If the size of the toilet paper roll is limited to fit within mounting brackets, then the existing installations can be used, but the storage space for wet wipes becomes extremely limited
Solution Approach 1:
The patent nests the container body within the hollow interior of the toilet paper roll, allowing the system to fit within standard mounting bracket dimensions while maximizing the use of the roll's internal hollow space for wipe storage.
Solution Approach 2:
The patent optimizes the container body's three-dimensional configuration to fit within the constrained space of the hollow roll interior, utilizing vertical and radial dimensions efficiently to maximize storage capacity within the limited volume available.

AI summary
A toilet paper roll holder with wet wipe is described. In one embodiment, a system includes an elongated container body, a first endcap, a second endcap, at least one connector, and a bias member. The elongated container body has a central first axis, an internal storage space, a first end, and a second end. The elongated container body fits within a toilet paper roll. The first endcap is coupled to the first end of the elongated container body. The second endcap is coupled to the second end of the elongated container body. The second endcap includes an access lid to provide access to the internal storage space. The at least one connector is to secure the system relative to a mounting location on a second axis. The bias member is on a third axis. The bias member is coupled between the at least one connector and the elongated container body.
