Dashboard Mounting Shell With Locking Plate for Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for securing portable electronic devices in vehicles fail to adequately mitigate vibrations during driving, leading to readability issues and discomfort for passengers, while also compromising airbag placement and storage space.
Innovation Solution
A shell and support assembly with a fixing plate that stabilizes the device by solidly attaching it to the dashboard, utilizing a notch-hook system for secure locking without requiring tools, and incorporating elastic return means for enhanced stability and automatic locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable electronic device is mounted on the dashboard using existing support devices, then the device can be used by the front passenger, but vibrations are transmitted to the device causing readability issues and discomfort
Solution Approach 1:
The patent applies prior cushioning by incorporating vibration-damping materials and isolation elements in the mounting structure before vibrations can be transmitted to the device. The support device includes elastic elements and damping components that are pre-installed to absorb and reduce vibration transmission from the dashboard to the electronic device, thereby preventing readability issues and user discomfort.
2Reliability
If the airbag is installed in the lower part of the dashboard, then safety standards are met, but storage space is reduced
Solution Approach 1:
The patent resolves this contradiction by utilizing vertical space and three-dimensional arrangement. The support device for the electronic device is designed to mount in the upper dashboard area, while the airbag remains installed in the lower dashboard. This dimensional separation allows both the safety requirement (airbag in lower position) and storage requirement (upper dashboard storage compartment) to coexist without interference, effectively using different spatial dimensions to satisfy conflicting requirements.
3Reliability
If a retractable support frame is used, then the device can be safely used with airbag compatibility, but the structure becomes complex and storage volume is limited
Solution Approach 1:
The patent extracts the essential function of vibration isolation and secure mounting from a complex retractable mechanism. Instead of using a retractable support frame with multiple moving parts, the invention employs a simplified fixed mounting structure that directly attaches the electronic device to the dashboard upper section. This extracted solution maintains airbag compatibility by preserving upper-dashboard installation while eliminating the complexity of retractable mechanisms and associated components.
4Object-affected harmful factors
If a fixed mounting structure is used, then vibrations are reduced, but installation requires tools and becomes more complex
Solution Approach 1:
The patent applies self-service by designing a mounting structure with self-aligning and self-locking features. The fixed mounting structure includes elastic elements and snap-fit components that automatically adjust and secure the electronic device during installation without requiring external tools. The structure's own elastic and mechanical properties enable it to perform the installation function, making the process tool-free while maintaining rigid vibration-reducing attachment.
