Drip Resistant Wood Graining Process Using Composite Rope
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wood graining processes for artificial props are not cost-effective, resource-efficient, and fail to provide durable, flexible, and safe solutions that maintain a realistic appearance, especially in harsh weather environments and entertainment settings where safety standards must be met.
Innovation Solution
A process involving strands of rope made from a fibrous matrix material, coated with a curable epoxy, drawn through a constricting orifice to form a composite rope, which is then cured to create a lightweight, heat-resistant, and flexible artificial wood prop with a realistic wood grain texture, using an armature and wire mesh for support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If expensive epoxy is manually sculpted to form artificial props, then the prop achieves a realistic appearance, but the manufacturing cost and labor requirements increase significantly
Solution Approach 1:
The patent uses pre-manufactured wood grain templates that are pressed into the epoxy coating to create realistic wood grain patterns. This copying approach eliminates the need for manual sculpting while maintaining realistic appearance, directly resolving the contradiction between manufacturing precision and ease of manufacture
Solution Approach 2:
The patent employs disposable wood grain templates that can be easily replaced. These templates provide consistent wood grain patterns without requiring skilled manual labor, reducing both labor costs and manufacturing complexity while maintaining realistic appearance
2Adaptability or versatility
If traditional artificial wood prop materials are used, then the prop can be molded into shape, but the prop loses durability and begins to melt or drip in harsh weather environments
Solution Approach 1:
The patent uses composite materials consisting of epoxy resin combined with wood grain templates and potentially other reinforcement materials. This composite structure provides both the moldability needed for prop construction and the thermal stability required to resist melting and dripping in harsh weather conditions
Solution Approach 2:
The patent modifies the material parameters by using thermosetting epoxy resins that undergo chemical curing to achieve high heat resistance. The material transitions from a moldable liquid state to a rigid, heat-resistant solid state, simultaneously achieving both moldability during construction and durability in service
3Strength
If heavy materials are used for artificial wood props, then the prop achieves structural strength, but the weight makes moving and installing the prop difficult
Solution Approach 1:
The patent employs composite materials that provide high strength-to-weight ratio. The epoxy resin matrix combined with reinforcement materials creates a structure that achieves necessary structural strength while remaining lightweight enough for easy movement and installation
Solution Approach 2:
The patent uses thin layers of epoxy coating applied over templates, creating strong but lightweight structures. This approach achieves structural integrity through optimized material distribution rather than bulk mass, reducing overall weight while maintaining strength
4Ease of manufacture
If current wood graining processes are used, then the prop can be constructed, but the process is not cost-effective and resource-efficient
Solution Approach 1:
The patent uses pre-manufactured wood grain templates that have been prepared in advance. These templates can be mass-produced and stored, allowing for efficient assembly of multiple props without repeating the complex wood grain creation process each time, thereby improving productivity and cost-effectiveness
Solution Approach 2:
The patent employs universal templates and standardized epoxy coating processes that can be applied to various prop types. This multi-functionality allows the same basic process and materials to serve multiple purposes, reducing overall resource consumption and manufacturing costs

AI summary
A process provides two or more strands of rope formed of a fibrous matrix material. Further, the process threads the strands singly and in parallel under tension into a coating container. In addition, the process applies a curable fluid matrix to at least some of the strands. The process also draws the strands through a constricting orifice to bond them together along their length to form a composite rope. Further, the process cures the composite rope to form a rigid structure. An apparatus comprises an armature, a wire mesh that is operably attached to the armature, and an epoxy coated rope that is operably attached to the wire mesh. The epoxy coated rope comprises glass fiber.
