Vehicle Door Handle System Identical Drive Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle door handle systems require two different drive devices due to mirror-symmetrical designs, leading to increased costs and variability, as well as differing installation spaces and wiring requirements for driver's and passenger's side doors.
Innovation Solution
The first drive device is mounted in a mirror-inverted manner compared to the second drive device, allowing for identical drive devices to be used on both sides with the same direction of movement, eliminating the need for different pin assignments and wiring adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two different drive devices are provided for driver's side and passenger's side doors due to mirror-symmetrical design, then the door handle system can be adapted to both sides, but the cost and device complexity increase
Solution Approach 1:
The patent applies asymmetry by mounting the drive devices in mirror-inverted positions on the carrier housings. Although the drive devices themselves are identical, their asymmetric mounting arrangement allows them to operate correctly on both driver's side and passenger's side doors, eliminating the need for different drive device variants while maintaining adaptability to both sides of the vehicle.
Solution Approach 2:
The patent inverts the mounting position of the drive devices relative to the carrier housings. By mounting the drive devices in mirror-inverted positions (i.e., opposite sides of the carrier housing), the identical drive devices can function correctly on both sides of the vehicle, reversing the conventional approach of using different drive devices for different sides.
2Shape
If different drive devices are used for driver's side and passenger's side doors, then mirror-symmetrical appearance is achieved, but manufacturing costs and variability increase
Solution Approach 1:
The patent implements universality by designing a single drive device that can be used on both driver's side and passenger's side doors. The drive device is designed with universal mounting capabilities that allow it to function on both sides when mounted in mirror-inverted positions, eliminating the need for different drive device variants and reducing manufacturing complexity and costs.
Solution Approach 2:
The patent uses asymmetric mounting of identical drive devices to achieve mirror-symmetrical appearance. By mounting the same drive device in mirror-inverted positions on opposite sides of the vehicle, the visual symmetry is maintained while the manufacturing complexity is reduced, as only one drive device design is needed.
3Adaptability or versatility
If drive devices are mounted with different orientations to achieve mirror-symmetry, then both sides can be served, but installation space requirements differ
Solution Approach 1:
The patent applies asymmetry in the mounting position of the drive devices on the carrier housings. By mounting the drive devices in mirror-inverted positions, the same drive device can be installed on both sides of the vehicle with consistent installation space requirements, as the asymmetric mounting compensates for the side-specific orientation needs while maintaining uniform space consumption.
