Solution Overview
Problem
Conventional electrical connection arrangements for refrigerant compressors in high-voltage applications, such as motor vehicles, require complex assembly processes and high material thickness for holding elements, leading to increased production costs and assembly effort, while also being prone to inaccuracies that compromise sealing integrity.
Innovation Solution
A connection arrangement featuring a holding element with positioning means on opposite sides and reinforcement means along its longitudinal sides, allowing for precise and quick assembly with reduced material thickness, and utilizing a shaped seal for fluid-tight closure, which simplifies the assembly and enhances the sealing quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional glass-to-metal-seal technology is used for electrical feedthroughs, then sealing integrity and electrical insulation are improved, but assembly complexity and production costs increase
Solution Approach 1:
The connection arrangement is divided into separate functional components: a holding element for mechanical support, shape elements for sealing, and positioning means for alignment. This segmentation allows each component to be optimized independently and simplifies the overall assembly process while maintaining sealing integrity through the coordinated interaction of these modular elements.
Solution Approach 2:
Positioning means are provided on the holding element before assembly to pre-establish the correct alignment and position of the electrical feedthrough in the housing opening. This preliminary positioning action ensures accurate placement and simplifies the subsequent assembly steps, reducing the skill level and time required for installation while maintaining sealing quality.
2Strength
If holding elements with high material thickness are used, then mechanical strength and sealing capability are improved, but production costs and assembly effort increase
Solution Approach 1:
Instead of uniformly thick holding elements, the design uses strategically placed reinforcement means at specific locations where mechanical strength is most needed, such as around the electrical connection points and at mounting interfaces. This localized reinforcement approach provides the necessary structural integrity while minimizing overall material usage and reducing assembly complexity compared to uniformly thick designs.
Solution Approach 2:
The holding element may incorporate composite construction combining different materials with complementary properties - for example, a base material providing overall structural support with reinforcing elements or coatings providing localized strength enhancement. This composite approach achieves high mechanical strength with reduced material thickness and simplified assembly compared to conventional homogeneous thick-walled designs.
3Manufacturing precision
If positioning means are added to the holding element, then assembly precision is improved, but device complexity increases
Solution Approach 1:
The positioning means are integrated directly into the holding element structure itself rather than being separate components. This merging of positioning functionality into the existing holding element minimizes the increase in device complexity while still providing the necessary assembly precision. The positioning features are formed as part of the holding element's geometry, requiring no additional parts or assembly steps.
4Stability of the object's composition
If reinforcement means are provided on longitudinal sides, then structural stability is improved, but material usage and production complexity increase
Solution Approach 1:
The reinforcement means may utilize curved or rounded geometric forms rather than sharp angular structures. This curvature can provide enhanced structural stability and stress distribution while being more amenable to conventional manufacturing processes such as stamping, bending, or molding. The curved reinforcement profiles can be formed in standard production operations, reducing the complexity compared to intricate angular or multi-component reinforcement structures.
