Motorized Side Door Opening Without External Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicles require manual door opening from the outside, which compromises safety and comfort, particularly in theft scenarios.
Innovation Solution
A motorized door opening system with a touch-sensitive or electromagnetic command interface that controls a motorized door mechanism to open and close the door autonomously, eliminating the need for manual handles or graspable elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual door handles and graspable elements are provided, then ease of operation is improved, but safety and theft prevention deteriorate
Solution Approach 1:
The patent removes traditional manual door handles and graspable elements from the door surface, extracting the vulnerable component that thieves could use. The door surface becomes smooth and continuous without protruding handles, eliminating the mechanical interface that could be exploited for forced entry while maintaining aesthetic continuity.
Solution Approach 2:
The patent replaces the mechanical manual handle system with an electronic/electromagnetic actuation system. A command receiving device (such as a touch-sensitive surface or electromagnetic receiver) replaces the mechanical handle, and an actuator mechanism with motor drives the door opening/closing actions automatically, substituting mechanical manual operation with automated electromechanical control.
2Reliability
If manual door handles are removed, then safety and theft prevention are improved, but ease of operation deteriorates
Solution Approach 1:
The patent introduces an intermediary command receiving device that mediates between the user's intent and the door actuation system. This device (touch-sensitive surface, electromagnetic receiver, or other input interface) serves as the new interaction point, allowing users to initiate door operations without direct mechanical contact with handles, thus maintaining ease of use while preventing theft.
Solution Approach 2:
The patent implements a self-service system where the door automatically executes opening and closing actions in response to commands, without requiring manual manipulation. The actuator mechanism autonomously performs the mechanical work of moving the door, eliminating the need for users to physically grasp and pull handles, thereby maintaining operational ease while enhancing security.
3Ease of operation
If traditional door handles are provided, then ease of operation is improved, but aerodynamic performance deteriorates
Solution Approach 1:
The patent extracts and removes traditional door handles from the door surface, creating a smooth, continuous exterior that eliminates protruding elements. This extraction of mechanical handles results in a streamlined door surface that reduces aerodynamic drag and improves the vehicle's overall aerodynamic performance while maintaining a clean, modern aesthetic.

AI summary
A motor vehicle includes a body, a side door hinged to the body so that it can rotate about an axis towards a side of the motor vehicle between a closed configuration and an open configuration; a motorized opening device, which is controllable to move the door from the closed configuration towards the open configuration; command receiving means to receive an opening request command for the door from the outside of the motor vehicle; and a control unit (ECU) configured to control the opening device so that the door rotates from the closed configuration towards the open configuration in response to the opening request command.
