Prefabricated Element Recess for HVAC Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of heating and cooling devices in prefabricated building elements is time-consuming and costly due to the need for manual creation of recesses in walls and ceilings, which are often inaccurate and inefficient, especially in conventional methods that rely on caulking and milling after the element is installed.
Innovation Solution
A flat prefabricated building element with a pre-designed recess on its surface to accommodate heating and/or cooling devices, featuring a heat-conducting profile with an omega-shaped receptacle for air conditioning pipes, and latching elements or adhesive layers for secure fixation, allowing for precise and efficient integration of heating and cooling systems during production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heating and cooling devices are installed after prefabricated building elements are assembled, then the building elements can be manufactured and delivered efficiently, but the installation process becomes time-consuming and costly due to manual creation of recesses
Solution Approach 1:
The patent applies preliminary action by pre-fabricating recesses in the building elements during manufacturing, before delivery to the construction site. This allows heating and cooling devices to be integrated more efficiently, as the recesses are already prepared and do not require manual creation during installation, thereby reducing on-site installation time while maintaining manufacturing efficiency.
Solution Approach 2:
The patent segments the building element into distinct functional zones, including dedicated recess areas for heating and cooling devices. This segmentation allows for standardized production of modular elements with pre-defined installation zones, improving both manufacturing efficiency and on-site assembly speed.
2Ease of operation
If manual chiseling and milling are used to create recesses for heating devices, then the prefabricated elements can be installed first, but the process generates noise, dust, and results in inaccurate dimensions
Solution Approach 1:
The recesses are pre-fabricated with precise dimensions during the manufacturing process using controlled industrial equipment, eliminating the need for inaccurate manual chiseling and milling on-site. This ensures high manufacturing precision while maintaining installation flexibility, as the precise recesses are ready for direct device placement.
3Productivity
If recesses are pre-formed in prefabricated building elements, then heating and cooling systems can be integrated more efficiently, but the manufacturing process becomes more complex
Solution Approach 1:
The manufacturing process is segmented into standardized steps for creating recesses, allowing for modular production. This segmentation reduces overall process complexity by breaking down the pre-fabrication into repeatable, controlled operations that can be efficiently integrated into existing manufacturing workflows, thereby improving on-site assembly speed without excessive complexity increase.
Solution Approach 2:
The pre-formed recesses are designed with universal dimensions and configurations that can accommodate various heating and cooling devices. This universality simplifies the manufacturing process by using standardized templates and tools for recess creation, reducing the need for custom fabrication while enabling efficient on-site assembly across different project requirements.
