Foil Sheet Fabric Overlay 3D Decorative Object Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for constructing three-dimensional objects, such as artificial landscapes, are time-consuming, require scarce materials like plaster impregnated gauze, and lack versatility due to the need for support structures and the difficulty in modifying shapes once the plaster sets, with protruding gauze causing painting and sanding issues.
Innovation Solution
A method using a foil sheet with an adhesive and a fabric layer, which provides self-supporting strength and can be easily shaped, eliminating the need for wadded newspaper or plaster impregnated gauze, allowing for post-application shaping and easier application of plaster or resinous materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plaster impregnated gauze is used with wadded newspaper support, then structural strength is achieved, but construction time increases and material availability decreases
Solution Approach 1:
The invention uses a composite material consisting of plaster impregnated gauze adhered to a flexible substrate (cardboard, Styrofoam, or wadded newspaper). This composite structure provides the necessary structural strength while the pre-formed substrate eliminates the need for time-consuming manual wadding, directly resolving the contradiction between strength and construction time
Solution Approach 2:
The flexible substrate is prepared in advance as a pre-formed support structure before the plaster gauze is applied. This preliminary action eliminates the need to create support structures during the construction process, reducing construction time while maintaining structural integrity
2Strength
If multiple layers of plaster impregnated gauze are applied, then desired configuration and structural strength are achieved, but the procedure becomes more complex and time consuming
Solution Approach 1:
The invention combines the support structure and the reinforcing layer into a single integrated unit by adhering the plaster impregnated gauze to the flexible substrate. This merging eliminates the need for multiple separate application steps and layers, simplifying the procedure while maintaining structural strength
3Strength
If plaster impregnated gauze is used, then structural strength is achieved, but gauze protrusion interferes with surface finishing
Solution Approach 1:
The flexible substrate acts as an intermediary between the plaster impregnated gauze and the final surface. It provides a smooth, continuous base that prevents gauze fibers from protruding through the plaster layer, thereby facilitating easier sanding and painting while the gauze beneath maintains structural strength
4Reliability
If plaster impregnated gauze is dipped in water for activation, then proper adhesion is achieved, but the procedure becomes messy and requires skill
Solution Approach 1:
The flexible substrate is prepared in advance with the appropriate adhesive properties or surface characteristics that enable direct adhesion of the plaster impregnated gauze without requiring water dipping. This preliminary preparation eliminates the messy water activation step while maintaining reliable adhesion
