Concealed Door Handle Assembly with Lockable Push-Push Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle door handle assemblies compromise aesthetic appeal and security, as they protrude from the vehicle's surface, making them vulnerable to unauthorized access and theft, while also being redundant with the advent of electronic door operation systems, necessitating a solution that maintains aesthetics, enhances security, and provides a reliable mechanical failsafe.
Innovation Solution
A concealed door handle assembly that integrates a door handle flush with the vehicle's surface, transitioning between concealed and operational states, featuring a lockable push-push mechanism for selective accessibility, and operable with both mechanical and electronic systems, eliminating redundant components and providing a secure, aesthetically pleasing means of access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional protruding door handle assembly is used, then the door can be easily opened, but the aesthetic appeal is compromised and security is reduced due to vulnerability to unauthorized access
Solution Approach 1:
The door handle assembly is designed to dynamically change its position between a retracted state (flush with door surface for aesthetics and security) and a deployed state (protruding for operation). The handle moves from a first position recessed in the door to a second position protruding from the door, allowing it to adapt between aesthetic/security requirements and operational requirements.
2Ease of operation
If a conventional protruding door handle assembly is used, then the door can be easily opened, but security is compromised due to vulnerability to unauthorized access and theft
Solution Approach 1:
The handle's dynamic positioning between retracted and deployed states allows it to remain hidden during parked periods, reducing visibility to potential thieves, while being readily accessible when needed for legitimate door opening operations.
Solution Approach 2:
The handle assembly is nested within a recess in the door surface when not in use, with the handle contained within the door thickness. This nesting approach hides the handle from external view and access, thereby improving security while maintaining ease of operation when deployed.
3Shape
If electronic door operation systems are used, then aesthetic appeal is improved, but reliability is reduced due to potential electronic failures
Solution Approach 1:
The door handle assembly serves multiple functions: it provides aesthetic appearance when retracted, enables manual door opening when deployed, and can interface with electronic door locking systems. This multi-functionality allows the same mechanical component to support both aesthetic requirements and reliable mechanical operation as a failsafe.
Solution Approach 2:
The mechanical handle assembly serves as a pre-prepared backup system that can take over if electronic systems fail. By maintaining a functional mechanical handle that can independently operate the door, the system cushions against the harmful effect of electronic failures before they become critical problems.
4Shape
If a concealed door handle assembly is used, then aesthetic appeal and security are improved, but device complexity increases
Solution Approach 1:
The dynamic movement mechanism allows the handle to transition between retracted and deployed positions, providing aesthetic and security benefits when retracted while maintaining operational capability when deployed. This dynamic approach achieves the desired aesthetic improvement without requiring permanently complex concealed mechanisms.
