Cigarette Paper Dispenser with Sliding Housing and Refill Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for sheets, such as cigarette paper, require complex alignment and disassembly for refilling, leading to inconvenience and risk of the sheet stack falling apart during insertion.
Innovation Solution
A dispenser design with a housing and support member that allows for easy insertion of a pre-aligned box of sheets through a third opening, featuring a freely movable sidewall and a spring-loaded mechanism for stable operation in various orientations, eliminating the need for disassembly and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the housing is fully removed from the support member for refilling, then the sheet stack can be inserted, but the alignment between support member and housing becomes complex and tedious
Solution Approach 1:
The box with the sheet stack is inserted through the third opening and nested within the housing, which itself is mounted on the support member. This nested arrangement allows the box to be refilled without removing the housing from the support member, eliminating alignment complexity while maintaining ease of operation
Solution Approach 2:
The system is segmented into distinct components: the support member, the housing, and the box with sheet stack. The box can be independently inserted through the third opening, allowing refilling operations to be performed on the box without affecting the housing-support member assembly, thus simplifying both operation and alignment
2Ease of manufacture
If the second sidewall of the box is rigid and fixed, then the box structure is simple, but the support plateau cannot be properly positioned and the stack may not be stable
Solution Approach 1:
The second sidewall is designed with a freely movable portion that can dynamically adjust its position. When the box is placed on the support plateau, this movable sidewall can shift to accommodate the stack, ensuring proper positioning and stability while maintaining a relatively simple box structure that is easier to manufacture than a fully rigid design with built-in adjustment mechanisms
3Quantity of substance
If the support plateau is large, then it can support larger stacks, but it may interfere with the flange portions of the box
Solution Approach 1:
The support plateau is designed with specific local dimensions that match the space between the flange portions of the box. This localized dimensional coordination allows the plateau to be sufficiently large to support the sheet stack while maintaining clear clearance from the flange portions, preventing interference and enabling both large stack capacity and simple component design

AI summary
The invention relates to a dispenser for dispensing sheets, comprising: a support member for supporting a stack of sheets; a housing for housing the stack of sheets, the housing being slidably mounted over the support, the support being inserted in the housing though a first opening at a first sidewall of the housing; the housing comprising: a second opening at a second sidewall opposite from the first opening for removing sheets from the stack; and a third opening at a third sidewall through which the stack of sheets can be inserted in the housing. By providing a third opening in a third sidewall through which the stack of sheets can be inserted in the housing, the stack of sheets can be inserted in the dispenser without requiring the housing to be fully removed from the support member.
