Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated actuators are designed for each trim component, then haptic feedback is optimized for specific components, but device complexity and production costs increase
Solution Approach 1:
The patent implements a universal actuator housing design that can accommodate different oscillating actuators and be integrated into various trim components throughout the vehicle. The standardized housing with consistent mounting features and actuator interfaces allows a single housing type to serve multiple locations and functions, eliminating the need for component-specific housing designs.
Solution Approach 2:
The actuator assembly is segmented into modular components: a standardized housing, removable oscillating actuator, and trim component interface. This segmentation allows the housing to be produced independently in large quantities as a standard part, while only the oscillating actuators need to be customized for specific applications, reducing overall system complexity.
2Reliability
If dedicated actuators are designed for each trim component, then haptic feedback matches component characteristics, but manufacturing precision requirements increase
Solution Approach 1:
The housing is designed as a universal component with standardized dimensions, mounting features, and actuator interfaces that can accommodate various oscillating actuators. This standardization reduces manufacturing precision requirements compared to designing unique housings for each trim component, while still achieving proper haptic feedback integration through the standardized interface design.
3Reliability
If multiple actuator parameters are adjusted for different locations, then haptic feedback is optimized locally, but ease of operation and calibration time increase
Solution Approach 1:
The patent acknowledges that different locations may require different haptic feedback characteristics, but the standardized housing provides a consistent platform that simplifies parameter adjustment. The uniform interface and mounting approach allow for more predictable and standardized parameter settings across different vehicle locations, reducing calibration complexity compared to completely custom designs.
4Reliability
If custom actuators are produced for each trim part, then haptic feedback fits component geometry, but productivity and production efficiency decrease
Solution Approach 1:
The standardized housing can be mass-produced as a single part design for use in multiple trim components throughout the vehicle interior. This universality significantly increases production efficiency and volume compared to manufacturing custom actuators and housings for each specific trim piece, while still achieving proper integration through the standardized interface design.
Solution Approach 2:
By segmenting the system into a universal housing and location-specific oscillating actuators, the housing can be produced in large quantities as a standard component, improving overall productivity while allowing customization only where necessary for specific actuator types.

Function Achieved in This Case
This solution enables standardized haptic feedback across different vehicle components, simplifying integration, reducing costs, and allowing for uniform haptic experiences regardless of the trim part's surface or weight, while maintaining optimal directional haptic feedback.
Implementation Method 1
an oscillating actuator causes a relative translational movement of the lid with respect to the container, generating a haptic vibration
Implementation Method 2
the lid comprises a first elastic element configured to bear against a first lateral wall of the container and a second elastic element configured to bear against a second lateral wall of the container

AI summary
Disclosed is an actuator housing (100) intended to provide haptic feedback in a vehicle, the actuator housing comprising: - a container (1) comprising a recess (6) configured to accommodate an oscillating actuator (3) and an insertion opening that opens into the recess (6), - a cover (2) configured to at least partially close the insertion opening of the container (1), the container (1) and the cover (2) being mounted so as to be able to move in translation relative to each other and configured such that, when the oscillating actuator (3) is accommodated in the recess (6), the oscillation of the oscillating actuator (3) causes the cover (2) to move in translation relative to the container (1), generating a haptic vibration in a direction of movement (Dx).
