Solution Overview
Problem
Existing underride protection devices for load transport vehicles face challenges in accommodating varying rear frame geometries and limited space, making it difficult to provide a uniform solution that optimally utilizes available space, especially for vehicles like rear tipper vehicles where space is restricted.
Innovation Solution
The underride protection device features an adjustable locking mechanism with a base holding element and a pivoting lever, allowing the locking bolt and recess to be fixed in various positions, enabling the underride protection barrier to be adjusted for optimal positioning relative to the vehicle frame, thus accommodating different vehicle configurations and space constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed locking mechanism is used for the underride protection barrier, then the device structure is simple, but it cannot accommodate different vehicle frame geometries and space constraints
Solution Approach 1:
The locking mechanism is designed with adjustable components that allow the barrier to be locked at multiple positions along its pivoting path. The locking device includes a locking element that can engage with different locking positions on the pivoting lever, enabling adaptation to various vehicle frame geometries and space constraints while maintaining a relatively simple overall structure.
Solution Approach 2:
The mounting arrangement is designed to be universally applicable to different load transport vehicles. The base holding element and pivoting lever combination with multiple locking positions creates a multi-functional system that can accommodate various rear frame configurations, making a single device type suitable for different vehicle makes and models.
2Area of stationary object
If the underride protection barrier is positioned close to the vehicle frame to maximize space utilization, then space efficiency improves, but the barrier may interfere with vehicle operations requiring rear access
Solution Approach 1:
The underride protection barrier is designed to pivot between a secured position (blocking the rear area for safety) and a release position (allowing access for operations). The adjustable locking mechanism enables the barrier to be positioned at optimal locations in between these extremes, balancing space utilization with operational accessibility based on specific vehicle requirements.
3Manufacturing precision
If the locking bolt and recess are fixed in specific positions, then the manufacturing precision is high, but the adaptability to different vehicle types is reduced
Solution Approach 1:
The locking system is segmented into multiple discrete locking positions along the pivoting lever. Instead of a single fixed locking point, the system provides multiple predetermined locking positions that can be selected based on the specific vehicle configuration, maintaining manufacturing precision while enabling adaptability.
Solution Approach 2:
The system allows changing the locking position parameter along the pivoting lever's path. By providing multiple discrete locking positions rather than a single fixed position, the system maintains precise manufacturing tolerances for each position while offering variability to accommodate different vehicle types and frame geometries.
