Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing testing devices for simulating vehicle crash pulses are limited by the weight of the framework supporting the image capturing units, which reduces the power available for accelerating the test body, affecting simulation quality and reproducibility.
Innovation Solution
A separate drive unit and rail guide are provided for the image capturing units, allowing them to be accelerated independently and synchronized with the test body, reducing the weight that needs to be accelerated and increasing the power available for simulating specific crash pulses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the image capturing unit is mounted on the same slide unit as the test body, then the device structure is simplified, but the weight increases and reduces the power available for acceleration
Solution Approach 1:
The device is divided into two separate slide units: one for the test body and another for the image capturing unit. This segmentation allows independent acceleration control and eliminates the weight penalty of carrying the image capturing unit on the test body slide unit.
Solution Approach 2:
A separate drive unit acts as an intermediary to accelerate the image capturing unit independently. This intermediary drive unit enables the image capturing unit to be accelerated without being mechanically coupled to the test body slide unit, thus avoiding the weight constraint.
2Device complexity
If the framework with image capturing unit is accelerated together with the test body, then the device structure is simplified, but vibrations are introduced and simulation quality decreases
Solution Approach 1:
The device is divided into two separate slide units: one for the test body and another for the image capturing unit. This segmentation allows independent acceleration control and eliminates the weight penalty of carrying the image capturing unit on the test body slide unit.
Solution Approach 2:
The image capturing unit is extracted from the test body slide unit and placed on a separate slide unit. This extraction removes the source of vibrations that would otherwise be introduced during acceleration, thereby improving simulation quality and reproducibility.
3Power
If the image capturing unit has its own separate drive unit, then the weight is reduced and power is increased, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions by controlling both drive units (for the test body and for the image capturing unit). This multi-functionality reduces the need for additional independent control systems, thereby limiting the increase in device complexity despite the addition of a separate drive unit.
