Roof Air Conditioner Frame Assembly for Simplified Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex integration of stiffening elements in existing roof air conditioning systems makes assembly difficult, requiring multiple components and additional fastening elements inside the vehicle, which complicates the installation process.
Innovation Solution
The proposed air conditioning device features a housing, an inner air distributor, and two identical frame units that serve as upper and lower frameworks. These frame units are designed with specific geometries and assembly features, such as recesses and stiffening elements, to simplify assembly and ensure proper tensioning on the roof.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple stiffening elements and fastening elements are integrated into the housing, then the structural stability and tensioning on the roof is improved, but the assembly complexity and installation difficulty increase
Solution Approach 1:
The patent combines multiple stiffening elements and fastening elements into a single integrated housing structure. The housing serves both as the enclosure for the air conditioning components and as the structural element that provides stiffening and mounting functions, eliminating the need for separate stiffening elements and reducing assembly complexity.
Solution Approach 2:
The housing is designed to perform multiple functions simultaneously: it encloses the air conditioning components, provides structural stiffening, and serves as the mounting interface with the roof through integrated fastening elements. This multi-functionality reduces the total number of components needed and simplifies the overall assembly process.
2Reliability
If multiple fastening elements are used inside the vehicle, then the secure mounting of the air conditioning system is improved, but the installation time and complexity increase
Solution Approach 1:
Multiple fastening elements are integrated into the housing structure, allowing them to be installed as a single unit rather than individually. This reduces the installation time while maintaining the secure mounting reliability, as the housing is attached to the roof in one operation with all fastening elements already in position.
Solution Approach 2:
The fastening elements are pre-positioned and integrated into the housing during manufacturing, so that during installation, the entire housing with its fastening elements can be mounted as a complete assembly. This preliminary integration eliminates the need for separate fastening operations and reduces installation time.
3Strength
If several components are bolted together to form the housing, then the structural strength is improved, but the manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The patent integrates the stiffening elements and fastening elements directly into the housing as a single manufactured component rather than assembling them from separate parts. This can be achieved through methods such as injection molding or other suitable manufacturing processes, which maintains structural strength while significantly simplifying manufacturing and assembly.

AI summary
The invention relates to an air-conditioning device for installing on a roof (101), comprising a housing (1), an inner air distributor (2), and two frame units (3, 4). The two frame units (3, 4) are identically designed, and each frame unit has a first face (11) and a second face (12). In the installed state, the frame units are arranged between the housing (1) and the inner air distributor (2) and are used as an upper frame unit (3) or a lower frame unit (4). The first faces (11) face each other, the second face (12) of the upper frame unit (3) faces the housing (1), and the second face (12) of the lower frame unit (4) faces the inner air distributor (2).
