Engineering Contradiction Analysis
1Loss of energy
If a large quantity of insulating material is used to create modular elements, then thermal insulation performance is improved, but the weight of the modular element increases
Solution Approach 1:
The modular element is segmented into distinct functional zones: insulating material regions for thermal insulation, hardening material regions for structural strength, and channel networks for material distribution. This segmentation allows each material to be used only where necessary, reducing overall insulating material quantity while maintaining insulation performance.
Solution Approach 2:
Different regions of the modular element have different material compositions and densities. The insulating material is concentrated in specific zones where thermal insulation is most needed, while structural zones use hardening material. This local differentiation optimizes both insulation performance and weight by avoiding unnecessary material usage in non-critical areas.
2Loss of energy
If a large quantity of insulating material is used to create modular elements, then thermal insulation performance is improved, but the cost increases
Solution Approach 1:
The modular element is segmented into distinct functional zones: insulating material regions for thermal insulation, hardening material regions for structural strength, and channel networks for material distribution. This segmentation allows each material to be used only where necessary, reducing overall insulating material quantity while maintaining insulation performance.
Solution Approach 2:
The patent optimizes the geometric parameters of the modular element, including channel dimensions, wall thicknesses, and material distribution ratios. By carefully controlling these parameters, the design achieves the required insulation performance with minimized material quantities, directly reducing manufacturing costs.
3Quantity of substance
If traditional modular elements with perpendicular channels are used, then concrete can be cast, but concrete consumption increases and flow problems occur
Solution Approach 1:
The channel network transitions from static perpendicular configurations to dynamic optimized pathways. The channels are designed with varying cross-sections and orientations that adapt to the concrete flow characteristics, allowing smooth material distribution throughout the modular element without bottlenecks or dead zones that would cause flow problems or excess consumption.
Solution Approach 2:
The patent optimizes the geometric parameters of the channels including diameter, length, orientation, and cross-sectional area ratios. These parameter optimizations ensure that concrete flows efficiently through the network with minimal resistance, reducing both concrete consumption and the risk of flow-related casting problems.
4Strength
If a network of steel or plastic bars is inserted inside the modules to increase strength, then structural strength is improved, but device complexity and manual labor increase
Solution Approach 1:
The patent merges the reinforcement function into the modular element structure itself by creating integrated hardening material channels. These channels form a unified structural network that provides both concrete distribution pathways and structural reinforcement, eliminating the need for separate steel or plastic bar networks and their associated assembly complexity.
Solution Approach 2:
The modular element's channel network serves multiple functions simultaneously: it distributes concrete during casting, provides structural reinforcement through the hardening material, and maintains the element's geometric integrity. This self-service approach eliminates the need for additional reinforcement components and manual assembly operations.
