Height-Adjustable Vehicle Blocking Device for Variable Wheel Diameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle blocking devices are inflexible due to variations in vehicle wheel diameters, limiting their use across different types of vehicles, particularly at distribution centers where multiple vehicle categories need to be accommodated.
Innovation Solution
A device with a guide track and height-adjusting means that allows the blocking mechanism to be adjusted in height to accommodate various vehicle wheel diameters, enabling engagement at optimal heights for both anti-roll and locking modes, and includes a detector for automatic or semi-automatic height determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-height blocking device is used, then the device structure is simple, but it cannot accommodate vehicles with different wheel diameters
Solution Approach 1:
The guide track is made height-adjustable, transforming from a fixed static structure to a dynamic one that can be repositioned vertically. This allows the blocking means to engage wheels of different diameters while maintaining a relatively simple overall device structure.
Solution Approach 2:
The blocking device is designed to accommodate multiple vehicle types with different wheel diameters through the height-adjustable guide track, making a single device universally applicable to various vehicles rather than requiring separate devices for each vehicle type.
2Adaptability or versatility
If the guide track is made height-adjustable, then adaptability to different vehicles is improved, but device complexity increases
Solution Approach 1:
The system uses a detector to automatically measure wheel diameter and control the guide track height adjustment, eliminating the need for manual adjustment and reducing operational complexity despite the added mechanical components.
Solution Approach 2:
Manual height adjustment is replaced with an automated control system that uses detectors and actuators to adjust the guide track height based on measured wheel dimensions, reducing the complexity of operation and improving precision.
3Reliability
If blocking means engage at incorrect height, then device structure is simple, but blocking effectiveness is reduced
Solution Approach 1:
A detector measures the wheel diameter and provides feedback to the control system, which then adjusts the guide track height accordingly. This closed-loop feedback ensures the blocking means engages at the correct height for maximum effectiveness.
Solution Approach 2:
The system performs preliminary measurement of the wheel diameter using a detector before the blocking operation, allowing the guide track to be pre-adjusted to the correct height, ensuring effective blocking from the outset.
