Dispenser insert for dispensing sheet products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recessed dispenser cabinets face issues with incompatibility and high friction when trying to retrofit dispensing mechanisms that dispense from the top of the stack, due to firmly attached bottom walls, leading to difficulties in refilling and potential tearing of sheet products.
Innovation Solution
A dispenser insert with a translational and rotational movable dispensing part relative to the magazine part, allowing the dispensing mechanism to be easily refilled without modifying the existing cabinet structure, compatible with various bottom wall shapes and structures, including slanted or curved surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the dispensing mechanism is firmly attached to the bottom wall of the cabinet for stable operation, then the dispensing stability is improved, but the refilling operation becomes difficult and time-consuming
Solution Approach 1:
The dispensing mechanism is designed with movable mounting elements that allow it to be dynamically repositioned. During dispensing, the mechanism remains firmly attached for stability. During refilling, the mechanism can be moved away from the bottom wall to allow access to the magazine for inserting new sheet product stacks, resolving the contradiction between stable dispensing and easy refilling.
2Strength
If the bottom wall is firmly attached to the cabinet structure for structural integrity, then the cabinet strength is improved, but the adaptation to different dispensing mechanisms becomes expensive and time-consuming
Solution Approach 1:
The mounting structure is segmented into detachable components that can be independently adjusted. The bottom wall remains firmly attached to maintain cabinet strength, while the dispensing mechanism uses separate mounting elements that can be reconfigured for different mechanisms without modifying the cabinet structure, reducing adaptation costs.
3Device complexity
If the total weight of the sheet product stack is applied to the leading sheet product for simple gravity dispensing, then the dispensing mechanism simplicity is improved, but the friction increases causing sheet product tearing
Solution Approach 1:
The sheet product stack is supported at multiple locations rather than relying solely on the leading sheet. Support elements are strategically positioned to distribute the weight load across multiple sheets and contact points, reducing the friction and pressure on the leading sheet while maintaining the simplicity of the gravity-based dispensing mechanism.
4Productivity
If multiple sheet products are withdrawn at a time for continuous dispensing, then the dispensing continuity is improved, but the sheet product waste increases
Solution Approach 1:
The dispensing mechanism incorporates a separation function that automatically detaches individual sheet products from the stack at the dispensing opening. This self-service separation ensures that only the required single sheet is dispensed while preventing multiple sheets from being accidentally withdrawn together, maintaining dispensing continuity while reducing sheet product waste.
