Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional air intake and discharge design is used with short air passages and single steel baffle, then the structure is simple, but sound insulation effect is poor
Solution Approach 1:
The air passage is divided into multiple segments with different directions and lengths. The air intake passage and air discharge passage are separated into distinct paths, preventing sound from traveling directly through a single short path. This segmentation increases sound transmission distance and reduces sound insulation penetration.
Solution Approach 2:
The air passages are designed to extend in multiple spatial dimensions rather than a single straight line. The air intake passage and air discharge passage are arranged in different spatial orientations, creating a three-dimensional sound path that increases the effective distance sound must travel and improves sound insulation performance.
2Loss of time
If modular design with prefabricated parts is not used, then customization is flexible, but installation time and labor cost increase
Solution Approach 1:
The small space product is divided into multiple independent modular components including wall modules, ceiling modules, and floor modules. Each module is prefabricated with standardized connection interfaces, allowing rapid assembly through simple connection operations without requiring complex on-site customization or extensive labor.
3Ease of manufacture
If wood products are used as main body materials, then structural strength is adequate, but recycling rate is low and environmental impact increases
Solution Approach 1:
The product employs composite material construction combining metal frames with decorative panels. The metal frame structure provides the primary structural strength and support, while decorative panels can be made from various materials including recyclable materials. This composite approach maintains structural reliability while improving material sustainability and recyclability.
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
The modular design significantly reduces installation time and difficulty, enhances soundproofing by lengthening sound paths and using sound absorption materials, and promotes environmental sustainability through recyclable components.

AI summary
A small mobile space includes a top plate, a bottom plate, and wall modules between the top plate and the bottom plate and is connected in sequence. The top plate, the bottom plate and the wall modules jointly define an accommodating space. A door assembly is arranged on at least one of the wall modules. A joint between every two adjacent wall modules, a joint between each wall module and the top plate, as well as a joint between the bottom plate and each of wall modules are clamped respectively by using a concave-convex structure. An air inlet module is arranged in the top plate and includes an air inlet channel, and a sound absorption component in the air inlet channel. An air inlet of the air inlet channel is communicated to the outside. An air outlet of the air inlet channel is communicated with the accommodating space.
