Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforced concrete materials are used in building outer walls, then structural strength and durability are improved, but heat energy accumulation increases and urban heat island phenomenon is exacerbated
Solution Approach 1:
The building wall is segmented into multiple layers including an outer wall layer and an inner wall layer with insulation material in between. This segmentation creates thermal zones that reduce heat transfer while maintaining structural integrity through the distributed layer structure.
Solution Approach 2:
The building wall uses composite material construction combining reinforced concrete outer layers with thermal insulation materials in the intermediate layer. This composite structure leverages the strength of concrete while incorporating materials with low thermal conductivity to reduce heat accumulation.
2Stability of the object's composition
If solar radiation accumulates on building outer walls, then building structure is maintained, but temperature of urban environment increases at night
Solution Approach 1:
An intermediary insulation layer is introduced between the outer wall that receives solar radiation and the inner wall. This intermediary layer acts as a thermal barrier that prevents heat from the outer wall from transferring to the interior and surrounding environment, thus stabilizing the building structure while reducing urban heat island effect.
Solution Approach 2:
The heat energy that would otherwise be transferred to the building interior and environment is extracted and blocked by the insulation layer. The insulation material takes out the harmful thermal energy from the heat transfer pathway while allowing the outer wall structure to maintain its structural function.
3Device complexity
If building panels are mounted close to the wall, then installation space is reduced, but heat dissipation efficiency decreases
Solution Approach 1:
The building panel system transitions from a two-dimensional surface mounting to a three-dimensional configuration with vertical spacing created by suspension members. This dimensional change creates an air gap that enables convective heat dissipation while the hanging members provide structural support and positioning.
Solution Approach 2:
The air gap created between the building panel and the wall functions as a pneumatic heat dissipation channel. Air circulation through this gap provides convective cooling, utilizing fluid dynamics principles to remove heat from the building envelope without requiring mechanical cooling systems.

AI summary
A building panel system include vertical members and horizontal members mounted to the vertical member, and a plurality of panel modules. Each of the panel modules includes a building panel, and a hanging member that is connected to the building panel and that is hung on a corresponding one of the vertical members and the horizontal members. The building panels of the panel modules cooperatively form a panel wall that is adapted to be spaced apart from a wall so that an air flow channel is formed between the panel wall and the wall and is adapted to communicate with an external space for air flowing.
