Dummy stabilizer system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dummy systems on movable platforms face instability, especially during rapid direction changes, which can lead to incorrect measurements by autonomous driving assistance systems due to the need for small and narrow platforms to minimize measurement errors.
Innovation Solution
A device with a stabilization element and coupling device is attached to the dummy, allowing for a releasable attachment between the dummy and the platform, providing adjustable pre-tension and magnetic coupling to absorb torque forces and maintain stability, even with small platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the platform is designed to be narrow and compact to minimize measurement errors, then the measurement precision is improved, but the dynamic stability of the dummy system deteriorates
Solution Approach 1:
The stabilizing element extends vertically from the platform upward to the fixing point on the dummy, utilizing the vertical dimension to provide stabilization without increasing the platform's horizontal footprint. This allows the platform to remain compact while achieving dynamic stability through the vertical stabilizing element that counteracts forces during rapid direction changes
2Measurement precision
If the platform size is reduced to minimize measurement errors, then the measurement precision is improved, but the device complexity increases due to the need for additional stabilizing mechanisms
Solution Approach 1:
The stabilizing function is extracted as a separate element (the stabilizing element) that can be independently attached to the dummy and platform, rather than integrating stabilization mechanisms into the platform structure itself. This allows the platform to remain simple and compact while the stabilizing element provides the necessary stabilization function
3Stability of the object's composition
If the stabilizing element is permanently fixed to ensure stability, then the stability is improved, but the ease of operation deteriorates due to inability to adjust or remove the dummy
Solution Approach 1:
The attachment between the stabilizing element and the dummy/platform is made dynamic rather than static, allowing it to be easily attached and detached. This enables the system to transition between stable operation mode (when attached) and adjustment/removal mode (when detached), providing both stability during operation and ease of adjustment when needed
