Paper product dispensing system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumable product dispensers often malfunction when products not designed for them are used, leading to suboptimal or no dispensing due to mismatched size and shape.
Innovation Solution
A paper product dispenser with a non-rectangular and non-circular product holding area, matched to the shape of the consumable product, such as a trapezoidal cross section for folded paper products, and optional perimeter inserts to change the cross-sectional shape, ensuring correct dispensing and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard rectangular or circular product holding area is used, then the dispenser structure is simple and easy to manufacture, but unauthorized products with mismatched shapes can be inserted leading to dispensing errors and jams
Solution Approach 1:
The patent applies asymmetry by designing the product holding area with a non-rectangular, non-circular cross-section (such as a trapezoidal shape) that does not conform to standard geometric forms. This asymmetric geometry ensures that only paper products with matching asymmetric shapes can be properly inserted and dispensed, preventing unauthorized products from being loaded while maintaining structural feasibility through defined wall configurations
2Reliability
If a non-rectangular cross section is used, then unauthorized product use is prevented and dispensing reliability is improved, but the area of the paper product is reduced which may affect user perception of value
Solution Approach 1:
The patent applies parameter changes by modifying the geometric parameters of the paper product, specifically transitioning from conventional rectangular sheets to folded configurations with non-rectangular cross-sections (such as trapezoidal folds). This changes the shape parameters while maintaining functional adequacy for hand drying, achieving waste reduction through optimized geometry without significantly compromising user perception of value
3Adaptability or versatility
If perimeter inserts are added to change the cross-sectional shape, then adaptability to different product shapes is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the product holding area into modular components, including removable perimeter inserts that can be independently manufactured and assembled. These inserts are positioned within the holding area to define the non-rectangular cross-section, allowing for easier manufacturing of individual parts and simplified assembly while maintaining the complex overall geometry needed for product shape adaptability
