Duct Joint Thermal Insulation with Integrated Supporting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of duct joints with thermal insulators on ventilators is hindered by low visibility and unstable footholds, making it difficult to adjust and align components, leading to reduced workability, increased weight, and higher costs due to the complexity of multiple components.
Innovation Solution
A duct joint design that integrates a blower with a thermal insulating unit mounted on an air passage unit, featuring a supporting mechanism to hold the insulator in place, eliminating the need for separate components and simplifying the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the duct joint is designed separately from the main body of the ventilator with multiple components (air passage unit, thermal insulating layer, and separate component), then dew condensation can be prevented and the structure can be adapted to building layouts, but the workability is lowered due to difficulty in adjustment and alignment, and the weight and cost increase
Solution Approach 1:
The patent combines the air passage unit and thermal insulating layer into a single integrated duct joint component. The thermal insulating layer is formed as an integral part of the duct joint body, eliminating the need for separate components. This merging reduces the number of parts that need to be aligned and assembled, significantly improving workability during installation while maintaining the thermal insulation function to prevent dew condensation.
Solution Approach 2:
The integrated duct joint design serves multiple functions simultaneously: it provides air passage, thermal insulation, and structural support for mounting to the ventilator. By combining these functions into a single component, the duct joint becomes more versatile and easier to install, as it eliminates the need to separately handle and align multiple components while still achieving all required functions.
2Adaptability or versatility
If the duct joint is designed separately from the main body of the ventilator with multiple components, then the duct joint can be changed in accordance with the layout of the building, but the weight and cost increase due to the increased number of components
Solution Approach 1:
The patent merges the air passage unit and thermal insulating layer into a single integrated component, reducing the total number of parts. This elimination of separate components directly reduces the overall weight of the duct joint assembly while maintaining the ability to adapt to different building layouts through the integrated design.

Function Achieved in This Case
This design enhances workability by reducing the risk of components coming off or being lost, decreases weight and cost, and allows for easier adjustment and repositioning of the duct joint, while preventing dew condensation and improving ventilation performance.

AI summary
The duct joint is mounted on a ventilator that contains an air blower. The duct joint to which a supply-air or exhaust-air duct is connected includes an air passage unit through which a supply airflow or an exhaust airflow can pass from the ventilator, and a thermal insulating unit that is laid on the air passage unit to cover the circumference of the air passage unit. A supporting mechanism is provided in the air passage unit to hold the thermal insulating unit. The supporting mechanism includes a protrusion formed in the air passage unit and an engaging unit that is bendable with respect to the air passage unit. The engaging unit is, when it is bent, engaged with the protrusion so that the thermal insulating unit is sandwiched and held between the engaging unit and the air passage unit.
