Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size sofa set design is used, then the structure is simple and easy to manufacture, but it cannot adapt to different indoor space structures and user needs
Solution Approach 1:
The sofa set is divided into multiple independent modular units including seat modules, armrest modules, and connecting modules. Each module can be independently manufactured and then assembled in different configurations to adapt to various space requirements. The seat module includes a seat plate with seat frame rods and connecting feet, while the armrest module includes armrest frame rods that can be detachably connected to seat modules.
Solution Approach 2:
The modular design creates universal components that can serve multiple functions and configurations. The seat modules can be arranged in series to form different长度的 sofas, and the armrest modules can be attached to different positions. The connecting feet with joint plates provide universal connection capabilities between different module types, allowing the same basic modules to create various sofa configurations suitable for different indoor spaces.
2Ease of operation
If a fixed-size sofa set is used, then the manufacturing process is simple, but the handling and transportation become cumbersome due to heavy weight and large volume
Solution Approach 1:
The sofa set is divided into multiple independent modular units including seat modules, armrest modules, and connecting modules. Each module can be independently manufactured and then assembled in different configurations to adapt to various space requirements. The seat module includes a seat plate with seat frame rods and connecting feet, while the armrest module includes armrest frame rods that can be detachably connected to seat modules.
3Adaptability or versatility
If a modular design with multiple components is used, then adaptability to different spaces is improved, but the assembly process becomes more cumbersome
Solution Approach 1:
The sofa set is divided into multiple independent modular units including seat modules, armrest modules, and connecting modules. Each module can be independently manufactured and then assembled in different configurations to adapt to various space requirements. The seat module includes a seat plate with seat frame rods and connecting feet, while the armrest module includes armrest frame rods that can be detachably connected to seat modules.
Solution Approach 2:
The connecting feet serve as intermediary components that facilitate the connection between seat modules and armrest modules. Each connecting foot includes a joint plate with multiple fixing holes that can align with corresponding holes on different module types. This intermediary design simplifies the assembly process by providing standardized connection interfaces, reducing the complexity of joining different modular components together.
