Handle-Less Vehicle Door Opening for Security and Convenience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicles require manual door opening from the outside, which compromises safety and comfort, particularly in terms of theft prevention and ease of use.
Innovation Solution
A motorized door opening device controlled by a touch-sensitive or electromagnetic signal receiver, allowing doors to open and close autonomously without handles or graspable elements, using a motor and a pushing assembly to rotate the door between configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual door handle with control is used, then the door can be opened from the outside, but the comfort of door opening is insufficient and theft risk increases
Solution Approach 1:
The patent removes the traditional external door handle and its manual control from the door surface, extracting these elements completely from the external interface. This eliminates the mechanical interface that thieves could manipulate while maintaining door opening functionality through a hidden push-button control accessible only after unlocking.
Solution Approach 2:
The patent introduces an electronic control system as an intermediary between the user and the door opening mechanism. The push-button control acts as a mediator that first unlocks the door electronically, then allows opening through a separate action, creating a two-stage process that prevents unauthorized direct mechanical access.
2Object-affected harmful factors
If external handles and controls are removed for security, then theft risk is reduced, but ease of operation deteriorates
Solution Approach 1:
The door opening system provides self-service through automated electronic unlocking and motorized door opening. Once the push-button is pressed, the system automatically unlocks the door and can even open it without requiring the user to manually pull or push, making the operation as convenient as traditional handles while eliminating external mechanical interfaces.
Solution Approach 2:
The patent replaces the traditional mechanical handle and latch system with an electronic control system and motorized opening mechanism. The mechanical interaction of pulling a handle is substituted with electronic button pressing and automated motor-driven door movement, eliminating the need for external mechanical manipulation points.
3Ease of operation
If a motorized opening device is added, then door opening comfort is improved, but device complexity increases
Solution Approach 1:
The motorized opening device is designed to perform multiple functions: it can open the door automatically, close the door automatically, and integrate with the electronic locking system. This multi-functionality justifies the added complexity by consolidating several door operations into a single integrated system rather than separate mechanisms for each function.
Solution Approach 2:
The patent merges the locking system and the opening/closing mechanism into a single integrated control system. The push-button control unit combines the unlocking function with the motorized opening/closing actuation, and the control unit ECU coordinates both the lock device and opening device operations, reducing overall system complexity through integration.

AI summary
A motor vehicle (1) includes a body (2), a side door (4) hinged to the body (2) so that it can rotate about an axis towards a side of the motor vehicle (1) between a closed configuration and an open configuration; a motorized opening device (5), which is controllable to move the door from the closed configuration towards the open configuration; command receiving means (7) to receive an opening request command for the door (4) from the outside of the motor vehicle (1); and a control unit (ECU) configured to control the opening device (5) so that the door (4) rotates from the closed configuration towards the open configuration in response to the opening request command.
