Modular Actuator Assembly with Replaceable Fastening Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing actuator arrangements for electric parking brakes and electromechanical service brakes in motor vehicles are complex and costly to produce, with limited adaptability to user-specific interface requirements.
Innovation Solution
The actuator arrangement features a modular design with separate fastening means that can be customized for different fastening requirements, including push-in and slip-on parts, and a plastic housing with a one-piece plug receptacle, allowing for adaptable and cost-effective production without altering the rest of the actuator arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the actuator arrangement uses a modular structure with integrated housing and fastening means, then the structure is compact and production is standardized, but adaptability to different customer-specific interface requirements is limited
Solution Approach 1:
The fastening means are separated from the main actuator arrangement and designed as independent replaceable parts. This segmentation allows different fastening configurations to be provided as separate modules that can be exchanged based on customer-specific requirements, without modifying the core actuator structure.
Solution Approach 2:
The actuator arrangement is designed with universal mounting interfaces that can accommodate multiple types of fastening means. The standardized interface allows a single actuator design to work with various fastening configurations (different hole patterns, mounting positions, and fastening types) through the interchangeable fastening parts.
2Adaptability or versatility
If different fastening configurations are integrated into the housing, then adaptability to different requirements is improved, but production cost and complexity increase
Solution Approach 1:
Fastening means are designed as separate replaceable parts rather than being integrated into the housing. This allows standardization of the main housing production while enabling customization through interchangeable fastening components, reducing tooling costs and simplifying manufacturing.
Solution Approach 2:
The design allows for easy replacement of fastening means when different customer requirements arise. Instead of producing different housing variants, the same housing can be used with different fastening parts, enabling cost-effective adaptation to different applications through part interchangeability.
