Laminated Wooden Panel with Embedded Denser Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wooden structural panels exhibit lower stability, less efficient sound insulation, shorter span, and sensitivity to moisture, making them less suitable for building construction, particularly in terms of wind stability and requiring additional coatings like cement or concrete for stability and insulation.
Innovation Solution
A prefabricated wooden structural panel with laminated wooden members and encapsulated denser materials, such as granular filler materials or reinforcement beams, to enhance stability, stiffness, and sound insulation without the need for external coatings, allowing it to function as both flooring and ceiling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional wooden structural panels are used, then the construction process is simpler initially, but additional coating materials (cement, concrete, rubble, or gravel) must be applied to achieve sufficient stability and stiffness
Solution Approach 1:
The patent applies composite materials by combining wooden structural members with embedded denser materials (such as concrete, metal, or stone elements) within the panel structure itself. This creates a hybrid composite panel that achieves the stability and stiffness of concrete while maintaining the aesthetic and environmental benefits of wood, eliminating the need for separate coating layers
Solution Approach 2:
The patent merges the structural panel with the coating function by integrating stabilizing and stiffening elements directly into the panel during manufacturing. The denser materials are embedded within the wooden structure, combining the functions of structural support and surface stabilization into a single integrated component, thereby simplifying the construction process
2Strength
If cement or concrete coating is applied to the wooden panel, then stability and stiffness are improved, but construction time increases due to additional steps and drying periods
Solution Approach 1:
The patent applies preliminary action by pre-integrating the stabilizing and stiffening elements into the wooden panel during off-site manufacturing. The denser materials are embedded within the wooden structure before installation, so that when the panel is installed on-site, it arrives as a complete, ready-to-use structural element requiring no additional coating or drying time
Solution Approach 2:
The panel structure serves itself by incorporating internal denser elements that provide the necessary stability and stiffness without requiring external coating materials. The wooden panel with embedded elements is a self-sufficient structural component that achieves its structural performance through its own integrated design
3Stability of the object's composition
If cement or concrete is used to coat the panel, then structural properties are enhanced, but moisture is introduced which may create unhealthy indoor climate
Solution Approach 1:
The patent applies local quality by strategically placing denser stabilizing elements only in specific locations within the wooden panel structure where they are most needed for structural performance. This localized integration provides the necessary stability while minimizing the overall moisture content compared to full-surface cement or concrete coating
Solution Approach 2:
The patent uses composite materials combining wood with moisture-resistant denser materials (such as metal or stone elements) that provide structural stability without introducing the moisture problems associated with cement or concrete coatings. The composite structure leverages the moisture resistance of the denser embedded elements while maintaining the aesthetic and environmental benefits of wood
4Productivity
If traditional wooden panels are used without additional materials, then the construction process is faster, but sound insulation between floors is insufficient
Solution Approach 1:
The patent applies composite materials by embedding denser materials (such as concrete, metal, or stone elements) within the wooden panel structure. These denser embedded elements act as sound barriers, significantly improving sound insulation performance between floors while maintaining the speed of installing pre-fabricated panels without separate ceiling materials
