Modular Vehicle Display Housing for Replaceable Keyboard Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices with integrated monitors and keyboards face challenges in accommodating different vehicle and AVN system specifications, necessitating replacement of both components together, which is inconvenient and inefficient.
Innovation Solution
A vehicle display device design featuring a detachable housing with a through hole and tool support allows the keyboard module to be easily separated and replaced using a tool, utilizing an elastic clip for assembly and a lever principle for disassembly, maintaining design integrity and avoiding damage to the monitor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the monitor and keyboard are integrated in a single housing, then the structural integrity and stability are improved, but the adaptability and ease of replacement deteriorate
Solution Approach 1:
The integrated display device is divided into separate functional modules: a monitor unit and a keyboard module. The keyboard module can be independently removed from the housing, allowing different keyboard specifications to be adapted without replacing the monitor. This segmentation resolves the contradiction by maintaining structural integrity of the overall device while enabling adaptability through modular components.
2Stability of the object's composition
If the monitor and keyboard are integrated in a single housing, then the structural integrity is improved, but the ease of repair and replacement deteriorate
Solution Approach 1:
The keyboard module is designed as a separable component that can be independently removed from the housing through a through-hole. This segmentation allows the keyboard to be easily replaced without affecting the monitor or requiring complete disassembly, thus improving ease of repair while maintaining the overall structural integrity of the device.
Solution Approach 2:
A through-hole structure serves as an intermediary access point in the housing, allowing a tool to be inserted and engage with the keyboard module for removal. This intermediary structure enables easy keyboard replacement without compromising the structural integrity of the main housing and monitor assembly.
3Reliability
If the keyboard is firmly fixed in the housing, then the stability and reliability are improved, but the ease of operation for replacement deteriorates
Solution Approach 1:
The keyboard module is designed to be extractable from the housing through a dedicated through-hole. During normal operation, the keyboard remains firmly fixed for reliability. When replacement is needed, the through-hole allows a tool to be inserted and engage with the keyboard module, enabling easy extraction without affecting the firm fixation during use. This resolves the contradiction between reliable fixation and ease of replacement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and efficient replacement of the keyboard module without affecting the monitor, reducing assembly time and minimizing damage risk, while accommodating various vehicle and AVN system specifications.
Implementation Method 1
the clip body may pass through the coupling hole and be elastically deformed to be caught and fixed in the coupling hole or come out of the coupling hole
Implementation Method 2
a tool inserted into the internal space through the through hole may be disposed between the rear surface of the keyboard module and a rear surface of the housing
