Magnetic Buckle Connection for Driving Recorder Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving recorders detach easily from their fixing bases due to vibration or inertia, especially on bumpy roads, due to a long vertical distance, compromising convenience and driving safety.
Innovation Solution
A combinational electronic apparatus with a reduced vertical distance, featuring a magnetic connection system comprising a first and second connection portion with magnetic attraction elements and buckle assemblies, allowing secure attachment to a surface with adjustable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the recorder is connected to the fixing base with a long vertical distance, then the recorder can be easily installed, but the recorder is easily detached due to vibration or inertia during driving
Solution Approach 1:
The connection assembly is divided into a fixing base portion and a connection device portion that can be separately installed and then combined. The fixing base is attached to the windscreen first, and the connection device is subsequently connected to it, allowing flexible installation while ensuring stable connection through the magnetic attraction mechanism.
Solution Approach 2:
The fixing base is pre-installed on the windscreen before the recorder is attached. This preliminary installation creates a stable foundation that reduces the vertical distance requirement, as the magnetic connection between the fixing base and connection device provides sufficient support without requiring a long mounting arm.
2Reliability
If the vertical distance from the recorder to the windscreen is reduced, then the recorder is more secure during driving, but the installation becomes more complex
Solution Approach 1:
The traditional mechanical connection system requiring long mounting arms and complex fastening mechanisms is replaced with a magnetic attraction system. The magnetic connection between the first magnetic attraction element in the fixing base and the second magnetic attraction element in the connection device provides strong holding force with simple structure, reducing both vertical distance and installation complexity.
Solution Approach 2:
The connection assembly serves multiple functions: it provides secure attachment through magnetic attraction, allows easy detachment and reattachment, enables angle adjustment of the recorder, and maintains a compact profile. This multi-functionality eliminates the need for separate components, simplifying the overall installation while ensuring reliability.
3Reliability
If a magnetic connection system is used, then the attachment security is improved, but the device complexity increases
Solution Approach 1:
The magnetic connection system merges the fixing base and connection device into a unified attachment mechanism. The magnetic attraction elements are integrated within the respective housings, and the buckle assemblies are combined with the magnetic elements to provide both magnetic holding and mechanical interlocking in a single compact structure, reducing overall complexity despite enhanced security.
Solution Approach 2:
The magnetic field acts as an intermediary force between the fixing base and connection device, providing attachment security without direct mechanical contact. This magnetic intermediary allows for easy attachment and detachment while maintaining strong holding force, and the buckle assembly serves as a secondary intermediary to lock the magnetic connection in place, creating a simple yet secure system.

Function Achieved in This Case
The apparatus provides a secure and convenient attachment, reducing the risk of detachment during vehicle movement and improving driving safety by minimizing the vertical distance and allowing a more discreet installation behind a rearview mirror.
Implementation Method 1
The first magnetic attraction element is mounted in the first housing... The second magnetic attraction element is mounted in the second housing at a position where the second connection portion is magnetically attracted to the first magnetic attraction element
