Double-Plate Tissue Dispenser Assembly to Prevent Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dispensers for cellulose products in sheet form face issues during the loading process, including the sliding plate 'jumping' out, jamming, and overturning, and are difficult to disassemble and clean, especially in public settings where contamination is a concern.
Innovation Solution
A dispenser design featuring a container with a double plate pushing assembly, where the upper and lower plates are constrained by elastic elements and guides, lowering the center of gravity and reducing jamming, and allowing for easier reassembly and cleaning, with a separable cover and customizable advertising features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single sliding plate is used to hold tissues in contact with the dispensing opening, then the tissues are constantly held in contact with the inner face of the cover, but the plate tends to jump out of the dispenser or jam in the guides during loading
Solution Approach 1:
The single sliding plate is divided into two separate plates: an upper plate that holds the tissues and a lower plate that forms the lower stop for the elastic element. This segmentation allows the lower plate to remain stationary during loading while the upper plate slides, preventing the jumping and jamming problems of the single plate design.
2Reliability
If the sliding plate is maintained constantly toward the top position by a spring, then the tissues are held in contact with the dispensing opening, but the dispenser becomes difficult to disassemble and reassemble for cleaning
Solution Approach 1:
The pushing assembly is segmented into separable components: the upper plate, lower plate, and elastic element can be easily disassembled and reassembled. The lower plate remains fixed while only the upper plate and elastic element need to be removed for cleaning, significantly simplifying the disassembly process compared to traditional single-plate designs.
3Stability of the object's composition
If the lower plate is arranged on the lower wall and slidingly constrained to guides, then the center of gravity is lowered and overturning moment is reduced, but the device complexity increases
Solution Approach 1:
The lower plate combines multiple functions: it serves as the lower stop for the elastic element, provides a sliding surface constrained by guides, and acts as a structural support element. By merging these functions into a single component, the design achieves stability without proportionally increasing complexity.
Solution Approach 2:
The lower plate is positioned at the bottom of the dispenser to lower the center of gravity, creating a more stable configuration. The gravitational potential energy is optimized by placing mass lower in the structure, reducing the overturning moment during loading operations.
