Reversible Roll Holders for Mixed Coreless and Plugged Rolls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispenser configurations are limited in accommodating different types and widths of rolls, particularly coreless rolls and rolls with axial plugs, making it difficult to reload and dispense various sheet products efficiently.
Innovation Solution
A reversible and interchangeable roll holder appliance system with opposing roll holders, where each appliance has a flexible attachment feature and pivot surfaces to accommodate rolls with or without axial plugs, allowing for adjustable spacing to fit various roll widths and configurations, enabling the use of different roll types within the same dispenser.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dispenser is designed with fixed roll holders for specific roll types, then the structural simplicity is maintained, but the adaptability to different roll types and widths is limited
Solution Approach 1:
The roll holder appliance is designed with opposing roll holders that can accommodate both coreless rolls and rolls with axial plugs. The pivot surfaces are configured to engage with either type of roll end, allowing a single appliance structure to perform multiple functions and support different roll configurations without requiring separate specialized holders for each roll type.
Solution Approach 2:
The roll holder appliance incorporates adjustable spacing between opposing roll holders, allowing the distance between them to be modified. This dynamic adjustment capability enables the same appliance structure to accommodate rolls of varying widths while maintaining structural integrity, thus improving adaptability without proportionally increasing complexity.
2Ease of operation
If the dispenser uses specialized roll holders for specific roll configurations, then the reliability for that specific configuration is improved, but the ease of operation for reloading different roll types deteriorates

AI summary
A dispenser suitable for dispensing a rolled product includes a housing having a back plate and a cover openably engaged with the back plate. Each of a pair of roll holder appliances disposed within the housing include a leg having a first end and a second end, and a first side and a second side. The first end has an attachment feature, and the second end has a first roll holder on the first side, and a second roll holder on the second side opposing and different from the first roll holder. The attachment feature of each appliance is removably attached to the back plate, each appliance being oriented with associated roll holders facing each other and suitably spaced apart so as to receive the rolled product therebetween.
