Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional heating structures use multiple cement casting and curing processes, then the heating system can be installed, but construction time and costs increase significantly
Solution Approach 1:
The heating structure is divided into separate modular components: an insulator layer, an ondol panel with integrated hot water passages, and a pipe housing. These modules can be manufactured independently and assembled without requiring multiple cement casting and curing cycles, thereby reducing construction time while maintaining installation reliability.
Solution Approach 2:
The invention uses composite construction combining the insulator (first material), ondol panel (second material), and pipe housing (third material) with different thermal and structural properties. This composite approach allows each layer to perform its specific function without requiring extensive cement work, reducing both time and cost while ensuring proper installation.
2Reliability
If conventional heating structures use multiple cement casting and curing processes, then the heating system can be installed, but construction costs increase
Solution Approach 1:
By segmenting the heating system into pre-fabricated modules (insulator, ondol panel, pipe housing), each component can be manufactured efficiently using optimized processes and materials. This reduces waste, lowers material costs, and eliminates the need for expensive multiple cement casting operations, thereby reducing overall construction costs while maintaining installation reliability.
Solution Approach 2:
The invention changes the construction parameters from traditional cement-based multi-layer casting to a modular assembly approach. This parameter change eliminates curing time requirements and reduces material costs associated with multiple cement layers, making the construction process more cost-effective while ensuring reliable installation.
3Reliability
If water leakage occurs in conventional heating structures, then the heating system fails, but complete dismantling and reconstruction are required
Solution Approach 1:
The heating system is segmented into modular components where the ondol panel with hot water passages is a separate replaceable unit. If water leakage occurs, only the affected ondol panel or pipe housing module needs to be removed and replaced, not the entire heating system. This segmentation dramatically simplifies maintenance while maintaining system functionality.
Solution Approach 2:
The hot water passages and pipes are extracted as separate, accessible components within the modular structure. The pipe housing can be removed to access and replace leaking pipes without dismantling the entire floor heating system, enabling easy repair while maintaining overall system functionality.
4Reliability
If conventional heating structures use multiple layers, then the heating system can be constructed, but the overall floor load increases
Solution Approach 1:
The invention uses thin-film or thin-walled modular components for the insulator, ondol panel, and pipe housing instead of thick cement layers. These thin-walled structures provide the necessary thermal insulation and structural support while significantly reducing the overall weight and floor load compared to traditional multi-layer cement constructions.
Solution Approach 2:
By using composite materials with high strength-to-weight ratios for the insulator, ondol panel, and pipe housing, the invention achieves reliable heating system construction with minimal weight. The composite structure provides adequate mechanical strength and thermal performance without the excessive weight of traditional multi-layer cement systems.

AI summary
Provided is a heating structure used for increasing an indoor temperature. The heating structure includes an insulator disposed on a top surface a structure, an ondol panel disposed on a top surface of the insulator, the ondol panel having a hot water passage including an inlet port and an outlet port, a pipe housing having a top surface to correspond to the top surface of the insulator, the pipe housing including a connection pipe receiving part therein, a hot water supply pipe having one end connected to the inlet port and the other end connected to a hot water supply part, the hot water supply pipe being received in the connection pipe receiving part, and a hot water discharge pipe having one end connected to the outlet port and the other end connected to a hot water discharge part, the hot water discharge pipe being received in the connection pipe receiving part. Thus, it may be unnecessary to wait until the casted cement is cured like the related art. Therefore, a construction period may be significantly reduced, and also, construction costs may be reduced. Also, if water leakage occurs in one of the ondol panels, only the leaking ondol panel may be replaced to easily maintain and repair the heating structure.
