Folding Wallpaper Table With Integrated Unrolling and Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wallpapering and cutting tables are bulkier and less versatile, as they require separate devices for unrolling and cutting paper, which is inefficient for the second type of paper that needs direct application on the wall and cutting into strips.
Innovation Solution
A folding wallpaper table with integrated unwinding and cutting systems within the frame, allowing for articulation of panels and a flat system for paper handling, combining the functions of a standard table with a cutting table without increasing bulk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate devices for unrolling and cutting paper are used, then the cutting function is available, but the table becomes bulkier and less versatile
Solution Approach 1:
The patent combines the unrolling system and cutting system into a single integrated table structure. The unrolling roller (10) and cutting roller (10') are housed within the same table frame, allowing both functions to be performed at one location rather than requiring separate devices.
Solution Approach 2:
The table is designed to perform multiple functions: it can unroll large sheets of paper for wall covering application, cut paper into strips using the cutting roller (10'), and provide a working surface for preparation. This multi-functionality eliminates the need for multiple separate tools.
2Adaptability or versatility
If the unrolling and cutting system is integrated into the table, then versatility improves, but the device complexity increases
Solution Approach 1:
The table is divided into distinct functional modules: the unrolling section with roller (10), the cutting section with roller (10'), and the support structure. Each module can be independently adjusted or maintained, reducing the complexity of the overall system while maintaining integrated functionality.
Solution Approach 2:
The table incorporates adjustable and movable components, such as the swivel shelf (2) that can rotate around axes (20), and extensions (3) that can be positioned as needed. This dynamic design allows the structure to adapt to different operational requirements without requiring a completely complex fixed structure.
3Ease of operation
If the swivel shelf and extensions are made movable, then ease of operation improves, but the stability during operation may be compromised
Solution Approach 1:
The swivel shelf (2) and extensions (3) are designed to be movable during setup and operation, allowing easy adjustment of the table configuration. However, once positioned, these components provide stable support for paper unrolling and cutting operations, combining adjustability with operational stability.

AI summary
The wallpaper table (25) has a fixed part (1) provided with an exterior crosspiece (8) and a horizontal crosspiece (8'). Symmetric crosspieces (9, 9'), the exterior crosspiece and the horizontal crosspiece support a plate (7). A pivoting table (2) is provided with a chassis (23) and a plate (24) that rotates around an axle (20) and another axle, where axles are integrated to the symmetric crosspieces. A roller (10) is turned via third axle (21) and fourth axle, and a paper roller to be cut into pieces is positioned on a support system (11).
