Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressor designs for motor vehicle air-conditioning systems have complex plug-in connections that require numerous components and large mounting spaces, leading to increased manufacturing costs, assembly times, and vulnerability to contamination.
Innovation Solution
A simplified arrangement for plug-connecting electrical connections using a single-piece mounting element with integrated sealing and fastening features, minimizing external components and reducing the need for screws and separate sealing elements, while ensuring hermetic sealing and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate sealing elements and screwed connections are used for plug-in connections, then reliable sealing and electrical connection are achieved, but the number of components increases, mounting space requirements increase, and assembly complexity increases
Solution Approach 1:
The patent combines multiple separate sealing elements and screwed connections into a single integrated sealing component that is molded as one piece. This sealing component simultaneously provides both sealing function and mechanical fastening function, eliminating the need for separate sealing elements and screws, thereby reducing the total number of components while maintaining reliable sealing and connection.
Solution Approach 2:
The integrated sealing component serves multiple functions simultaneously: it provides sealing against contaminants, acts as a mechanical fastener through integrated screwed connections, and provides structural support for the plug-in connectors. This multi-functional design reduces component count and simplifies the overall assembly.
2Reliability
If multiple separate sealing elements and screwed connections are used for plug-in connections, then reliable sealing is achieved, but manufacturing costs and assembly times increase
Solution Approach 1:
By merging multiple sealing elements and fastening components into a single integrated sealing component, the assembly process is simplified. Instead of installing multiple separate components sequentially, the integrated component can be installed as one unit, significantly reducing assembly time and operational steps while maintaining the same sealing reliability.
3Strength
If screwed connections are used for mounting plug-in connections, then secure fastening is achieved, but mounting space requirements increase and vulnerability to contamination increases
Solution Approach 1:
The integrated sealing component combines the fastening function and sealing function in a single element that mounts through a reduced opening in the housing. The integrated design allows the fastening and sealing features to overlap spatially, reducing the required mounting space compared to separate screwed connections and sealing elements that would require distinct mounting areas.
4Adaptability or versatility
If multiple separate components are used for plug-in connections, then functional requirements are met, but the risk of contamination from assembly increases
Solution Approach 1:
By integrating multiple functions into a single sealing component, the number of assembly operations is reduced. Fewer assembly steps mean fewer opportunities for contaminants to enter the housing during the assembly process. The integrated component is typically pre-assembled and sealed, reducing exposure to contamination risks during final assembly.

AI summary
An arrangement for plug-connecting electrical connections through a housing, in particular a device for driving a compressor. The arrangement exhibits at least one plug-in connection with at least one plug-in connector for transmitting electrical energy, as well as one mounting element for mounting the at least one plug-in connector. The mounting element can be fixed on the housing. The mounting element exhibits on one inner surface of the housing, which encloses the volume, an opening for mounting a fastening element for fixing the mounting element on the housing. The opening is produced in such a way that it starts from the inner surface, extends into the mounting element and ends in the mounting element. The fastening element is arranged in such a way that it is inserted into the opening from the volume enclosed by the housing through a pass-through opening, that is produced in the housing.
