Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing natural fiber objects from Zostera marina fibers fail to achieve the necessary thermal, acoustic, and fire-repellency properties required for use as approved building materials, particularly in meeting industry standards for fire classification.
Innovation Solution
A method involving mixing Zostera marina fibers with a binding agent and fire retardant, pre-forming an intermediate object, heating above the binding agent's melting point, compressing, and allowing to cool, while ensuring even fire retardant distribution and penetration, which results in a denser, more homogeneous product with enhanced fire retardancy and acoustic properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Zostera marina fibers are used as natural building material, then natural fire-resistance and carbon neutrality are achieved, but insufficient fire classification and inadequate thermal/acoustic properties prevent approval as building material
Solution Approach 1:
The patent combines Zostera marina fibers with binding agents and fire retardant additives to create a composite material that achieves Class B-s1, d0 fire classification. The composite structure integrates natural fibers with synthetic components to meet building material standards while maintaining natural fire-resistance properties.
Solution Approach 2:
The patent modifies the physical and chemical parameters of Zostera marina fibers through treatment processes, including density adjustment, fire retardant impregnation, and thermal processing, to achieve the required fire classification and thermal/acoustic properties for building material approval.
2Reliability
If fire retardant is applied to surface of the object, then fire retardant properties are improved, but insufficient penetration and saturation of fibers result
Solution Approach 1:
The patent applies fire retardant to the Zostera marina fibers before forming the final product structure, ensuring thorough penetration and saturation of the natural fibers. This preliminary treatment allows the fire retardant to be evenly distributed throughout the fiber matrix before compression and binding.
Solution Approach 2:
The patent utilizes the porous structure of Zostera marina fibers to absorb and retain fire retardant solution, allowing deep penetration into the fiber network. The natural porosity of the seaweed fibers enables efficient impregnation and saturation with fire retardant chemicals.
3Reliability
If density of the natural fiber object is increased, then thermal and acoustic properties are improved, but manufacturing complexity and process control difficulty increase
Solution Approach 1:
The patent controls density as a key parameter during the compression and binding process, optimizing it to achieve the required thermal and acoustic insulation properties. By systematically adjusting compression pressure and binding agent content, the patent achieves consistent density control that meets building material standards without excessive process complexity.

Function Achieved in This Case
The method achieves a Class B-s1, d0 fire classification and superior sound absorption, meeting industry standards and offering improved handling, storage, and production efficiency, with the natural fiber object possessing exceptional thermal and acoustic properties.
Implementation Method 1
heating the intermediate object above a melting and/or softening point temperature of the binding agent
Implementation Method 2
the Z. marina fibres advantageously absorb some of the fire retardant allowing for a more saturated object

AI summary
A method for producing a Zostera marina fiber object includes mixing natural fibers with a solid binding agent and a fire retardant, heating the mixture above a melting and/or softening point temperature of the binding agent, forming the mixture into the shape of the natural fiber object and applying a coating of the fire retardant to the surface of the natural fiber object.
