Automobile Haptic Actuator with Integrated Electrical Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle control devices with haptic feedback are costly and time-consuming to assemble, especially when customizing options like backlighting and touch-sensitive surfaces, and require electrical wires or connectors for actuator connection, which complicates the assembly process.
Innovation Solution
A control device with an actuator that uses two electrical connection pins to connect directly with conductive tracks on the electronic circuit, eliminating the need for wires or connectors, and a mechanical coupling via a pedestal for robustness and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electrical wires or connectors are used to connect the actuator to the support, then reliable electrical connection is achieved, but assembly time increases and assembly cost increases
Solution Approach 1:
The patent merges the electrical connection function and mechanical mounting function into a single integrated actuator component. The actuator body directly contacts conductive areas on the support structure, eliminating the need for separate electrical wires or connectors. This integration allows simultaneous achievement of reliable electrical connection and rapid assembly, as the actuator is mounted to the support in a single operation that provides both mechanical support and electrical connectivity.
2Reliability
If traditional electrical wires or connectors are used to connect the actuator to the support, then reliable electrical connection is achieved, but assembly cost increases
Solution Approach 1:
The patent merges the electrical connection function and mechanical mounting function into a single integrated actuator component. The actuator body directly contacts conductive areas on the support structure, eliminating the need for separate electrical wires or connectors. This integration reduces assembly cost by reducing the number of components and assembly steps, while maintaining reliable electrical connection through the direct contact interface.
3Strength
If additional holding means are used to secure the actuator, then mechanical strength is improved, but assembly complexity increases
Solution Approach 1:
The patent merges the electrical connection function and mechanical mounting function into a single integrated actuator component. The actuator body directly contacts conductive areas on the support structure, serving both electrical and mechanical functions simultaneously. This eliminates the need for additional holding means such as separate fasteners or mounting brackets, thereby reducing assembly complexity while maintaining adequate mechanical strength through the integrated design.
