Vehicle AV Driving Assembly Chassis Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing audio/video system for vehicles has poor assemblability due to hidden motor and back-and-forth motion components, making it difficult to identify and repair faults, leading to reduced productivity and increased defective products.
Innovation Solution
A driving assembly with a separable main and low-surface chassis design that exposes the motor and back-and-forth motion member, allowing easy identification and repair, along with a reinforced slide chassis and a bracket to firmly secure the motor, improving visibility and assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the motor part and back-and-forth motion member are mounted on the low-surface chassis with the main printed circuit board, then the system structure is compact, but the assemblability deteriorates because components are hidden and difficult to access
Solution Approach 1:
The system is divided into two separate chassis: the main chassis and the low-surface chassis. The motor part and back-and-forth motion member are mounted on the low-surface chassis, which is positioned below the main printed circuit board. This segmentation allows components to be accessible from below while maintaining overall system compactness.
2Device complexity
If the motor part and back-and-forth motion member are hidden behind the main printed circuit board, then the system structure is simplified, but the ease of repair deteriorates because faulted parts cannot be easily identified or accessed
Solution Approach 1:
By separating components onto the low-surface chassis below the main printed circuit board, the design maintains structural simplification while enabling easy access to motor and motion components for repair and maintenance without requiring disassembly of the main circuit board area.
Solution Approach 2:
The low-surface chassis acts as an intermediary platform that carries the motor part and back-and-forth motion member, allowing these components to be accessible from below while maintaining their functional integration with the main system above.
3Ease of operation
If the monitor is tilted at a designated angle, then the viewing comfort is improved, but the device complexity increases due to the monitor tilting apparatus
Solution Approach 1:
The monitor is made tiltable through a mechanical apparatus that allows adjustment to designated angles. The tilting mechanism provides dynamic positioning capability, enabling the monitor to be adjusted for optimal viewing comfort while maintaining a relatively simple structural implementation.

AI summary
The present invention relates to a driving assembly of an audio/video system, more particularly, to a driving assembly of an audio/video system for a vehicle, in which a motor part and a back-and-forth motion member are mounted on a low-surface chassis, and a connecter mounted on the motor part is connected to a main printed circuit board and cable for controlling a motor. Thus, if there are faulted parts in the motor part or the back-and-forth motion member, or in other parts for controlling the motor part of the main printed circuit board, any one can easily identify and see the faulted parts to be changed or repaired, simply by separating the main chassis from the low-surface chassis. As a result, assembly efficiency of the driving assembly of the AV system is much improved.
