Paper dispenser with a housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper dispensers are limited to holding only two paper rolls, with no flexibility to accommodate different types of paper and limited capacity for reserve rolls, which restricts their functionality and adaptability.
Innovation Solution
The housing is divided into a base part and an attachment part with a middle part inserted between them, featuring guide tracks in the side walls that allow for multiple paper roll positions, enabling modular design, increased capacity, and adaptable coding for various dispenser types, while avoiding excessive weight load on reserve rolls through meandering guide tracks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the housing is designed as a one-piece device with fixed positions for dispenser roll and reserve roll, then the structure is simple and easy to manufacture, but the capacity is limited to only two paper rolls and lacks flexibility to accommodate different types of paper
Solution Approach 1:
The housing is divided into a base part and an attachment part that can be connected together. The base part contains the output unit with the dispenser roll, while the attachment part can hold additional reserve rolls. This segmentation allows the dispenser capacity to be expanded from two rolls to potentially four or more rolls by adding more attachment parts, directly resolving the contradiction between increased capacity and structural complexity.
2Quantity of substance
If removable supports are provided in the guide track to define dispensing and reserve positions, then the dispenser can accommodate multiple paper rolls, but the weight load on the lowest reserve roll may become excessive and impair the refill function
Solution Approach 1:
The guide track is designed with a meandering path that includes horizontal sections instead of a purely vertical alignment. This dimensional change in the guide track layout distributes the weight load more evenly across multiple support points and reduces the cumulative weight burden on the lowest reserve roll, allowing the dispenser to hold more paper rolls without impairing the refill function of the bottom roll.
3Adaptability or versatility
If the housing is horizontally subdivided into base part and attachment part, then modular construction is enabled and adaptability is increased, but the manufacturing precision requirements for connecting elements increase
Solution Approach 1:
The connecting elements between the base part and attachment part are designed with universal features that allow for easy alignment and connection. The connecting elements include standardized interfaces that can accommodate slight variations in manufacturing tolerances, enabling modular construction with reasonable precision requirements while maintaining the adaptability and versatility of the dispenser system.
