Dual-Roll Bathroom Tissue Holder with Concealed Backup Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toilet tissue holder devices often require users to manually switch between rolls, which can be inconvenient when the first roll is depleted mid-use, and they lack a discreet storage solution for the second roll.
Innovation Solution
A holder device featuring a bracket mountable to a vertical surface with a telescopically adjustable shaft to support the first roll and an upwardly extending holder for the second roll, along with a wrapping option to conceal and keep the second roll accessible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single roll holder is used, then the device structure is simple, but the user must manually switch rolls which causes loss of time and inconvenience
Solution Approach 1:
The patent applies preliminary action by pre-positioning a second roll of toilet tissue in the holder assembly before it is needed. The second roll is stored in the holder and can be immediately accessed via the wrapper removal mechanism, eliminating the time loss associated with manual roll switching. The system prepares the backup roll in advance, making it ready for instant deployment when the first roll is depleted.
2Ease of operation
If a second roll is stored openly in the holder, then accessibility is improved, but aesthetic appeal deteriorates due to visible storage
Solution Approach 1:
The patent applies the nesting principle by placing the second roll of toilet tissue inside a wrapper that is itself stored within the holder assembly. The wrapper acts as a container within the holder, creating a nested structure. This allows the second roll to be concealed within the wrapper, maintaining aesthetic appeal while preserving accessibility through the wrapper removal mechanism.
Solution Approach 2:
The patent uses a flexible wrapper (thin film) to enclose the second roll of toilet tissue. This flexible shell provides a discreet covering that conceals the second roll's presence, maintaining aesthetic appeal. The wrapper can be easily removed to access the second roll, ensuring accessibility is not compromised by the concealment.
3Shape
If a wrapper is added to conceal the second roll, then aesthetic appeal is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the holder assembly to serve multiple functions: it holds the first roll on the shaft, stores the second roll in the holder, and provides a wrapper for concealment. The wrapper removal mechanism integrates with the existing holder structure, allowing a single component to perform multiple functions (holding, concealing, and providing access to the second roll) without significantly increasing overall device complexity.

AI summary
A bathroom tissue holder assembly for holding a pair of rolls of toilet tissue includes a bracket that is mountable to a vertical support surface at a point located proximate a lavatory. A shaft is provided and the shaft removably engages the bracket to support a first roll of toilet tissue on the bracket. A holder is coupled to and extends upwardly from the bracket to support a second roll of toilet tissue. In this way the second roll of toilet tissue is accessible when the first roll of toilet tissue is depleted. A wrapping is formable into a cylinder and the wrapping can be wrapped around the second roll of toilet tissue when the second roll of toilet tissue is being stored on the holder.
