Segmented MPE Axle Casing for Sealing and EMC Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Active chassis systems face challenges in maintaining tightness and accessibility of construction groups within sealed casings, which are often compromised due to limitations in configuring casing parts to minimize electromagnetic interference (EMC) and environmental influences.
Innovation Solution
An apparatus comprising two motor-pump groups and an electronic unit, all housed within a closed, multiplicity of partial casings that are permanently interconnected and sealed with adhesive, allowing for greater geometrical configuration and accessibility while maintaining airtight and waterproof integrity, and providing electromagnetic shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the overall casing is sealed tightly against environmental influences and electromagnetic radiation, then the tightness and EMC protection are improved, but the accessibility of construction groups and mounting simplicity deteriorate
Solution Approach 1:
The overall casing is divided into multiple partial casings that can be separately assembled and disassembled. This segmentation allows the casing to maintain tightness when assembled while enabling easy access to construction groups when disassembled, resolving the contradiction between sealed integrity and accessibility.
Solution Approach 2:
Construction groups are nested within the partial casings, which themselves are nested within the overall casing structure. This nested arrangement allows components to be accessed by opening only the relevant partial casing rather than the entire sealed structure, maintaining both tightness and accessibility.
2Object-affected harmful factors
If the overall casing is configured to minimize electromagnetic interference, then the EMC exposure is reduced, but the configuration flexibility and accessibility deteriorate
Solution Approach 1:
The casing is segmented into modular partial casings that can be independently configured and arranged. This segmentation provides configuration flexibility for EMC optimization while maintaining overall sealing, as each module can be designed and positioned to minimize electromagnetic interference without compromising accessibility.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement of partial casings and construction groups to achieve EMC minimization. By arranging components in different spatial dimensions and orientations within the modular structure, the system achieves both EMC optimization and configuration flexibility.
3Reliability
If the partial casings are permanently interconnected to ensure tightness, then the sealing integrity is improved, but the assembly complexity and mounting difficulty increase
Solution Approach 1:
The casing system is segmented into standardized partial casings with uniform connection interfaces. This segmentation with standardization reduces assembly complexity despite permanent interconnection, as each module follows the same connection pattern, making the permanent bonding process more straightforward and less complex.
