Out indicator sheets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional out indicator sheets on tissue dispensers are difficult to see once the product is placed in a dispenser, and they do not provide information on the remaining tissue quantity, serving only as a replacement indicator without additional functionality.
Innovation Solution
The development of a dispensing device and method for forming tissue sheets with an improved out indicator, where the image is printed across the center of the tissue fold, enhancing visibility and serving as both an advertisement and a visual indicator of the remaining tissue quantity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an out indicator sheet is placed in a dispenser, then it indicates when the product needs replacement, but it becomes difficult to see and does not provide information on remaining tissue quantity
Solution Approach 1:
The tissue product is divided into multiple sections, with specific out indicator sheets positioned at different locations within the dispenser. These segmented indicators show different stages of tissue depletion (e.g., 25%, 50%, 75% remaining), providing progressive information about remaining quantity while maintaining reliable replacement indication.
Solution Approach 2:
The out indicator information is extended from a single binary state (needs replacement/not) to multiple dimensional levels by showing different quantities remaining. The indicator system now provides information across multiple dimensions: replacement urgency and remaining tissue quantity, transforming a simple alert into a comprehensive status display.
2Device complexity
If a simple replacement indicator is used, then the device is simple, but it does not serve as an effective advertisement or provide additional functionality
Solution Approach 1:
The out indicator sheet serves multiple functions simultaneously: it indicates when replacement is needed, shows the remaining tissue quantity, and provides advertising space. By making the indicator multi-functional, the system maintains relative simplicity while gaining advertisement capability and additional information provision.
Solution Approach 2:
The advertising message is merged with the functional indicator elements. The out indicator sheet combines replacement alerts, quantity information, and promotional content into a single integrated component, eliminating the need for separate advertising materials and maintaining device simplicity.
3Ease of operation
If visual information is enhanced for better visibility, then the indicator is easier to see, but the manufacturing process becomes more complex
Solution Approach 1:
Enhanced visual features such as contrasting colors, bold graphics, and high-visibility patterns are applied locally to specific areas of the out indicator sheet where they are most needed for visibility, rather than uniformly across the entire sheet. This allows improved visibility while controlling manufacturing complexity by targeting enhancements only where necessary.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides clear visual indication of the remaining tissue quantity and serves as an effective advertisement, improving user experience by ensuring the consumer is aware of when to replace the product.
Implementation Method 1

AI summary
Embodiments are directed to a dispensing device and methods of using a dispensing device having an improved out indicator. The dispensing device includes a housing having a cavity. A tissue stack is disposed within the cavity, the tissue stack including a plurality of tissue sheets folded along a crease. An aperture is formed in a top surface of the housing such that a tissue sheet is removable from the cavity through the aperture. A portion of the tissue sheets includes an out indicator formed along a centerline of each tissue sheet and across the crease.
