Layered Ventilation Conduit for Concrete-Embedded Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ventilation systems for buildings, particularly air ducts in concrete slabs, require complex and time-consuming installation processes due to the rigidity of galvanized rigid pipes, necessitating adjustable elbows, multiple parts assembly, adhesives, tape, and manual steel wire securing.
Innovation Solution
A ventilation conduit section comprising stacked layers of galvanized steel or similar materials with a sinusoidal pattern and hook configuration for easy connection and sealing, covered with a polymer-based anti-corrosion material and thermal insulation, allowing for quick assembly and secure attachment using an elastic band and hook system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid pipes are used for ventilation installation, then structural strength and stability are improved, but installation complexity and time consumption increase significantly
Solution Approach 1:
The ventilation conduit is divided into multiple modular sections that can be independently manufactured and then easily connected on-site. Each section contains integrated attachment features, eliminating the need for complex field assembly of rigid pipes, elbows, and sealing components.
Solution Approach 2:
The conduit combines rigid structural layers (for strength and shape retention) with flexible outer layers (for corrosion resistance and ease of handling). This composite construction maintains structural integrity while enabling simpler installation compared to traditional rigid pipes.
2Reliability
If traditional rigid pipe assembly methods are used, then connection reliability is achieved, but installation productivity decreases
Solution Approach 1:
Attachment features, sealing elements, and connection mechanisms are pre-integrated into the conduit sections during manufacturing. This preliminary preparation eliminates time-consuming field operations such as manual wire cutting, pipe cutting, and sealing application, while ensuring reliable connections.
Solution Approach 2:
Multiple functions (structural support, corrosion protection, sealing, and attachment) are merged into a single integrated conduit component. This consolidation eliminates the need for separate adhesives, tapes, and securing mechanisms, thereby improving installation speed without compromising connection reliability.
3Adaptability or versatility
If multiple separate components are used for ventilation conduit, then adaptability to different installation configurations is improved, but device complexity and assembly time increase
Solution Approach 1:
The conduit sections are designed with universal attachment features and standardized connection interfaces that can accommodate various installation configurations and orientations. This multi-functionality provides the adaptability of multiple components while maintaining a simple, integrated structure.
4Strength
If manual steel wire securing is used to attach rigid pipes, then secure attachment to structure is achieved, but installation time and labor requirements increase
Solution Approach 1:
Attachment features are pre-formed and integrated into the conduit sections during manufacturing, eliminating the need for manual wire cutting and securing operations on-site. The pre-prepared attachment mechanisms provide secure mounting while significantly reducing installation time and labor requirements.
