Vehicle Sliding Door Actuator Flat Profile Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door actuators for vehicles are difficult to install, occupy too much space, and fail to meet climatological conditions due to insulation issues with power supply and cables, making them unsuitable for use in load compartments of vehicles, especially in existing vehicles and refrigerated applications.
Innovation Solution
A vehicle sliding door actuator with a movable movement unit along a profile section and a coiled cord within a cable duct, integrated with power supply and sensors, designed to be flat and easily insulated, meeting IP 69 standards for reliability and electronic insulation, and easily coupled to a vehicle's electrical system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing sliding door actuators are installed in load compartments, then door operation function is achieved, but installation difficulty increases and space requirements conflict with loading space
Solution Approach 1:
The actuator is divided into modular components: a profile section with integrated cable duct, a movement unit with motor and drive mechanism, and separate mounting elements. This segmentation allows independent installation of each module, simplifying the overall installation process in load compartments.
Solution Approach 2:
The cable duct is integrated directly into the profile section structure, and the movement unit combines motor, drive mechanism, and mounting features in a single assembly. This merging reduces the number of separate components and installation steps, directly addressing the ease of installation requirement.
2Ease of operation
If actuators are mounted in load compartment, then sliding door function is achieved, but space consumption increases reducing loading capacity
Solution Approach 1:
The actuator profile section is designed with a flat, elongated cross-section that extends along the door rather than projecting into the loading space. By changing the dimensional orientation from a bulky three-dimensional form to a flattened configuration, the actuator fits within the door structure without encroaching on valuable loading volume.
3Reliability
If power supply and cables are installed in load compartment, then actuator operation is enabled, but insulation reliability decreases under climatological conditions
Solution Approach 1:
The cable duct is nested within the profile section structure, creating a protected internal pathway for electrical cables. This nested configuration shields the power supply and control cables from direct exposure to climatological conditions in the load compartment, maintaining insulation reliability while enabling actuator operation.
Solution Approach 2:
The cable duct provides a protective enclosure for electrical cables, acting as a barrier against moisture and temperature extremes. This protective shell ensures that the power supply and control signals remain reliable even when the actuator operates in challenging climatological environments.
4Adaptability or versatility
If actuators are adapted for existing vehicles, then versatility is improved, but installation difficulty increases
Solution Approach 1:
The profile section and movement unit are designed as universal components with standardized mounting features that can be adapted to different door types and vehicle models. This universality allows the same actuator design to be installed in various existing vehicles without requiring custom modifications, thereby improving versatility while maintaining installation simplicity.
