Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cold rooms and refrigeration systems are not environmentally friendly due to the use of non-sustainable insulation materials and lack of sustainable construction methods.
Innovation Solution
The use of solid wood for walls and ceilings, combined with insulating materials like wood fiber, to create a self-supporting and energy-efficient cold room structure, which can be integrated into modular building systems for flexible and sustainable construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional insulation materials are used in cold rooms, then insulation performance is achieved, but environmental friendliness deteriorates
Solution Approach 1:
The patent applies composite materials by combining solid wood structural elements with wood fiber insulation material. The wall structure consists of a outer solid wood shell, an intermediate wood fiber insulation layer, and an inner solid wood shell, creating a composite construction that achieves both thermal insulation and environmental sustainability. This composite approach resolves the contradiction by integrating materials that provide both insulation performance and ecological compatibility.
Solution Approach 2:
The patent changes the material parameters from conventional synthetic insulation materials to natural wood fiber materials with specific thermal properties. The wood fiber material has a thermal conductivity of 0.04-0.08 W/(m·K), which provides adequate insulation performance while being environmentally friendly. This parameter change in material selection resolves the contradiction between insulation effectiveness and environmental compatibility.
2Object-affected harmful factors
If solid wood is used for walls and ceiling, then environmental friendliness is improved, but structural strength and insulation capability must be maintained
Solution Approach 1:
The patent uses composite material construction with three distinct layers: an outer solid wood shell providing structural strength and weather resistance, an intermediate wood fiber insulation layer providing thermal isolation, and an inner solid wood shell providing interior structural support. This composite structure maintains both strength and insulation capabilities while using environmentally friendly solid wood materials throughout.
Solution Approach 2:
The patent applies local quality by assigning different functions to different parts of the wall structure. The outer wood shell is designed for structural strength and exterior protection, the intermediate wood fiber layer is optimized for thermal insulation, and the inner wood shell provides interior structural support and finishing. Each local component is optimized for its specific function while contributing to the overall environmental friendliness of the structure.
3Adaptability or versatility
If modular building systems are used, then construction flexibility is improved, but assembly complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the cold room into modular building components that can be independently manufactured and assembled. The wall structures with integrated insulation and the solid wood elements are pre-fabricated as modules, allowing flexible construction and easy adaptation to different cold room sizes and configurations. This segmentation provides construction flexibility while keeping individual module complexity manageable.
Solution Approach 2:
The patent employs universal design principles where the solid wood components serve multiple functions: structural support, thermal insulation framework, and aesthetic finishing. The modular elements are designed to be multi-functional, reducing the number of separate components needed and simplifying the overall assembly process despite the flexibility in configuration options.
