Vehicle Navigation Memory Mounting Module Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
On-board vehicle navigation devices face challenges in accurately reading data from hard disks due to vibrations and shocks experienced during vehicle motion, as existing solutions like damping elements are not effective in protecting the memory units from damage.
Innovation Solution
A memory unit mounting module that includes a support plate, spring elements to absorb shocks, and damping elements to decelerate external motion forces, ensuring the memory unit remains functional and protected from vibrations and shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the memory unit is directly secured to the housing of the navigation device, then the device structure is simple, but the memory unit cannot properly read data under shocks and vibrations during vehicle motion
Solution Approach 1:
The patent applies beforehand cushioning by introducing spring elements and damping elements into the mounting structure before shocks and vibrations occur. The spring elements are pre-configured to deflect under shock loads, and the damping elements are pre-positioned to absorb vibrational energy, thereby protecting the memory unit from damage before the harmful effects can occur during vehicle motion.
Solution Approach 2:
The patent uses spring elements and damping elements as intermediary components between the housing and the memory unit. These intermediaries absorb and isolate the shocks and vibrations transmitted from the vehicle environment to the memory unit, allowing the memory unit to remain protected while still being securely mounted to the housing.
2Reliability
If damping elements are mechanically locked during transportation, then the disk drive is protected from damage, but the damping elements could be destroyed or displaced by strong shocks such as when the computer falls or is dropped
Solution Approach 1:
The patent applies dynamics by making the mounting structure movable and adaptable rather than fixed. The spring elements can dynamically compress and expand in response to varying shock conditions, and the damping elements can move within their mounting structures to absorb different magnitudes of shock forces. This dynamic capability allows the system to protect against both normal vibrations and strong shocks without being destroyed or displaced.
