Device for heating and/or cooling with a ventilator unit and a method for attaching such a ventilator unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating and cooling devices require complete dismantling for fan unit replacement or maintenance, which is inconvenient and can lead to damage, especially when water is involved, and they may not be visually appealing when the fan unit is visible externally.
Innovation Solution
A device design that allows the fan unit to be inserted horizontally and raised vertically into the device without dismantling, with a rigid elongated fan unit that is not visible externally, enabling easy replacement and maintenance without disassembling the entire unit, and a plug-in or slide-in connection for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the fan unit is permanently installed in the device, then the device structure is simple and stable, but the fan unit cannot be replaced without dismantling the entire device
Solution Approach 1:
The device is divided into separable modules: the fan unit becomes an independent replaceable component while the heat exchanger and housing form the main body. This segmentation allows the fan unit to be removed and replaced without dismantling the entire device, resolving the contradiction between ease of repair and device complexity.
Solution Approach 2:
The fan unit is extracted from the permanent installation and made into a removable component that can be taken out through an opening in the housing. This extraction enables easy replacement of the fan unit while maintaining the integrity of the main device structure.
2Ease of operation
If the fan unit is made flexible and articulated, then it can be easily installed, but the electrical connections can be damaged
Solution Approach 1:
The fan unit is designed as a rigid segmented module with electrical connections made at fixed points. This segmentation allows the unit to be handled as a complete module during installation, preventing damage to electrical connections while maintaining installation ease.
Solution Approach 2:
Instead of making the fan unit flexible to achieve ease of installation, the invention inverts the approach by making the housing opening and installation path flexible/adaptable to accommodate the rigid fan unit. This inversion maintains both electrical connection reliability and installation ease.
3Ease of repair
If the fan unit is arranged visible from outside, then installation and maintenance is easier, but the device appearance is compromised
Solution Approach 1:
The fan unit is accessed through a opening in the housing that allows insertion from the outside without requiring the fan unit to be visible. This dimensional approach to access (through the housing structure rather than from the front) resolves the contradiction between ease of repair and device appearance.
Solution Approach 2:
The housing opening acts as an intermediary that provides access to the fan unit without exposing it externally. This intermediary structure allows maintenance personnel to install and remove fan units while keeping the device appearance intact from the outside.
