Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If various prefabricated line implementations are provided for different applications, then adaptability to different installation conditions is improved, but device complexity and the need for additional connection elements increases
Solution Approach 1:
The fire protection module is designed with universal attachment capabilities that allow it to be used with different positioning modules and formwork sleeves. The module can be attached to various substrates (formwork, walls, ceilings) through different positioning modules, making a single fire protection module design applicable to multiple installation scenarios without requiring additional connection elements.
Solution Approach 2:
The invention combines the fire protection module, positioning module, and formwork sleeve into an integrated assembly where the fire protection module serves as a central component. This merging eliminates the need for separate connection elements between these components, as they are designed to work together as a unified system with direct attachment mechanisms.
2Manufacturing precision
If the fire protection module is separately manufactured and subsequently installed in the formwork sleeve, then manufacturing precision is improved, but ease of operation and assembly simplicity deteriorates
Solution Approach 1:
The line implementation assembly is segmented into distinct modules (fire protection module, positioning module, formwork sleeve) that can be manufactured separately with high precision using optimized processes for each component type. These segmented modules are then designed with complementary attachment features that enable simple on-site assembly without requiring complex alignment or additional connection elements.
3Adaptability or versatility
If the assembly is designed to be flexible for quick adaptation to different component thicknesses, then adaptability is improved, but ease of operation and simplicity of assembly deteriorates
Solution Approach 1:
The assembly incorporates adjustable and replaceable components that allow dynamic adaptation to different installation conditions. The positioning module can be replaced or adjusted to accommodate different component thicknesses, and the formwork sleeve length can be varied. These dynamic adjustments are designed to be simple operations that maintain assembly simplicity while providing the needed flexibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and flexible adaptation to various installation conditions, provides reliable fire protection, and ensures easy assembly and disassembly, with the fire protection module effectively sealing the implementation room during fires and maintaining stability under load.
Implementation Method 1
The fire protection element can consist of an intumescent material that enlarges its volume when the heat increases and thus closes the wall breakthrough
