Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall decoration methods are labor-intensive, prone to errors, and result in inconsistent quality, while modern buildings with thin partition walls suffer from inadequate sound insulation and noise issues.
Innovation Solution
A prefabricated wall modular decoration assembly using conventional materials like paint, wallpaper, or ceramic tiles, combined with a movable laminating layer and protective layer to create a sound-insulated air gap, simplifying installation and adding antibacterial properties with silver or copper ions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional wall decoration materials (paint, wallpaper, fabric, leather, ceramic tiles) are used with manual processes, then decorative functionality is achieved, but labor intensity is high, installation time is long, and quality consistency cannot be guaranteed
Solution Approach 1:
The patent applies preliminary action by pre-assembling the decorative panels with all components (conventional decorative materials, latex layers, plasticized stem locking layers, and air gaps) in a controlled factory environment before installation. The panels are pre-cut to exact dimensions and pre-locked together, so that during installation, workers simply need to attach the complete panels to the wall without manual finishing work. This resolves the contradiction by transferring complex manufacturing steps to the production phase, making installation simple and fast.
Solution Approach 2:
The patent segments the wall decoration system into modular panels, each containing a complete set of decorative materials and structural components. By dividing the large-scale wall covering task into smaller, pre-assembled modules, the installation process becomes much simpler and faster, while maintaining quality consistency. Each panel is an independent unit that can be installed separately, reducing labor intensity and installation time.
2Manufacturing precision
If manual decoration processes are used, then flexibility in material selection is maintained, but quality consistency deteriorates due to varying worker experience and craftsmanship
Solution Approach 1:
The patent ensures quality consistency by performing all critical assembly operations in advance under controlled factory conditions. The conventional decorative materials are precisely attached to panels, latex layers are uniformly applied, and plasticized stem locking layers are systematically installed before the panels leave the factory. This preliminary assembly eliminates the variability introduced by different workers' skills during on-site installation, as the quality-critical steps are completed in a standardized production environment with proper equipment and oversight.
3Area of stationary object
If thin partition walls are used to maximize interior space, then space utilization is improved, but sound insulation performance deteriorates
Solution Approach 1:
The patent applies local quality by incorporating air gaps specifically at the panel interfaces where sound transmission occurs. The conventional decorative materials and structural layers are arranged with deliberate air spaces between them, creating localized sound insulation zones at critical noise transmission paths. This allows thin walls to maintain their space-saving advantage while providing effective noise blocking at the decoration layer without requiring the entire wall structure to be thicker.
Solution Approach 2:
The patent creates a composite wall decoration structure combining conventional decorative materials (paint, wallpaper, fabric, leather, or ceramic tiles) with air gaps and multiple layers (latex and plasticized stem locking layers). This composite construction provides sound insulation functionality while maintaining the thin profile needed for maximizing interior space. The combination of different materials with varying densities and acoustic properties creates effective noise barriers within the limited wall thickness.

AI summary
The present invention discloses an assembly of prefabricated wall modular decoration, comprising a conventional decorative material, a plate, a movable laminating layer and a protective layer. The conventional decorative material being mounted on the surface of the plate, a number of movable laminating layers being evenly spaced between the plate and the protective layer making a sound-insulated air gap between them, and the protective layer being mounted on the surface of the wall. The present invention also discloses an installation method for the assembly above. Due to the traditional decorative material, the plate, the active lamination layer, and the protective layer of the present invention are set to be installed on the wall in turn, together with the sound-insulated air gap within the structure, which is not only simple to manufacture and easy to install, but also has better sound absorption performance which could reduce the noise nuisance.
