Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If combustible plastic materials are used, then material flexibility and application versatility are improved, but fire safety and health protection deteriorate due to soot and toxic fume release
Solution Approach 1:
The fire protection system is divided into separate functional layers: a transparent plastic layer providing flexibility and application versatility, and a transparent fire protection layer containing intumescent material for fire safety. This segmentation allows each layer to perform its specific function without compromising the other properties.
Solution Approach 2:
The invention uses a composite structure combining transparent plastic material with transparent intumescent fire protection material. This composite approach enables the system to simultaneously achieve the flexibility and versatility of plastic materials while incorporating the fire safety and non-toxic properties of intumescent materials.
2Illumination intensity
If transparent plastic layers are used, then visibility and aesthetic properties are improved, but fire protection effectiveness deteriorates due to limited material choices
Solution Approach 1:
By combining transparent plastic material with transparent intumescent fire protection material in a layered composite structure, the invention achieves both transparency for visibility and fire protection effectiveness. The intumescent layer provides reliable fire protection through its expansion and insulating properties while maintaining transparency.
Solution Approach 2:
The fire protection layer is designed with specific local properties - transparency in the visible range for maintaining visibility, while containing intumescent materials that activate under fire conditions to provide thermal insulation and protect the underlying plastic layer. Each layer has optimized properties for its specific function.
3Reliability
If intumescent materials are added to polymers, then fire retardancy is improved, but polymer properties and transparency deteriorate
Solution Approach 1:
Instead of mixing intumescent materials with the polymer matrix (which would compromise transparency), the invention segments the system into separate layers: a transparent plastic layer and a transparent fire protection layer containing the intumescent material. This allows the intumescent material to provide fire retardancy without interfering with the transparency of the plastic layer.
Solution Approach 2:
The transparent plastic layer acts as an intermediary between the transparent fire protection layer and the environment, allowing light transmission while the fire protection layer with intumescent material provides fire safety. The plastic layer mediates the functional requirements of both transparency and fire protection.
4Device complexity
If fire protection layers are made compact, then device complexity is reduced, but fire protection performance may deteriorate
Solution Approach 1:
The compact fire protection system achieves effective fire protection performance through a composite layered structure. The combination of transparent plastic material and transparent intumescent fire protection material in thin layers provides sufficient fire safety without requiring complex multi-component systems or thick layers.
Solution Approach 2:
The invention optimizes the thickness and composition parameters of each layer to achieve effective fire protection in a compact design. By carefully controlling the parameters of the plastic layer and fire protection layer, sufficient fire safety is achieved without increasing structural complexity or requiring thick layers.
