Motorized Tailgate Drive Integrating Acoustic Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive arrangements for motorized tailgate adjustments in vehicles lack effective and perceivable acoustic feedback to users, often relying on cables and being insufficiently noticeable, especially when the feedback is emitted through remote control devices.
Innovation Solution
Integrating an acoustic indicator directly into the drive arrangement, allowing for straightforward electrical connection and placement near the user, enabling clear and low-outlay acoustic feedback during motorized adjustments, with options for various feedback types and flexible control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If acoustic feedback is provided via remote control device, then feedback can be supplied to user, but acoustic feedback is not sufficiently perceptible and cabling involves high outlay
Solution Approach 1:
The acoustic indicator is integrated directly into the drive arrangement, merging the feedback function with the drive components. This eliminates the need for separate remote control devices and extensive cabling, reducing system complexity while maintaining effective acoustic feedback to the user.
Solution Approach 2:
The drive arrangement itself serves as the intermediary for acoustic feedback, replacing the remote control device as a mediator between the drive system and the user. This direct integration ensures perceptible feedback without requiring additional cabling infrastructure.
2Loss of information
If acoustic indicator is integrated into drive arrangement, then acoustic feedback becomes clearly perceptible and cabling is minimized, but drive arrangement structure becomes more complex
Solution Approach 1:
The acoustic indicator is combined with existing drive components such as the motor housing or drive module, utilizing available space and structural elements. This merging approach provides clear acoustic feedback while minimizing additional structural complexity by leveraging existing drive arrangement components.
3Loss of information
If acoustic feedback is emitted via remote control device in user's pocket, then feedback can be supplied, but feedback is not sufficiently perceptible
Solution Approach 1:
The drive arrangement serves as the intermediary for acoustic feedback, positioning the acoustic indicator close to the user during operation. This eliminates the remote control device as a mediator and ensures acoustic feedback is directly perceptible to the user without requiring them to be in close proximity to a separate device.
Solution Approach 2:
The acoustic indicator is positioned locally within or near the drive arrangement, creating a localized acoustic feedback zone close to the user. This local positioning ensures that acoustic feedback is clearly perceptible to the user during tailgate operations, regardless of their exact position.
