Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for locking vehicle fold-down sides and tailgates, such as spring-brake and pull-rotate structures, face issues with reliability, load capacity, and ease of operation, particularly under varying environmental conditions.
Innovation Solution
The Angular Rotation Locking Mechanism (ARLM) employs a mechanical structure comprising a lever, locking bases, ball screws, and a locking blade, allowing for adjustable and vibration-resistant locking and unlocking, with a double-ended alloy steel shaft and wing gasket for enhanced stability and ease of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If spring-brake mechanism with hook structure is used, then the structure is simple, but the life is not high and clamping ability depends heavily on the spring
Solution Approach 1:
The patent replaces the spring-based mechanical system with a purely mechanical locking system using a shaft, locking blade, and position pin. This substitution eliminates spring dependency while maintaining structural simplicity, thereby improving reliability and service life without sacrificing ease of construction.
2Reliability
If pull and rotate structures using shaft to lock are used, then the locking is reliable, but the mechanism is heavy and difficult to operate
Solution Approach 1:
The patent introduces an adjustable shaft that can be positioned at different angles and locked in place, transforming a static heavy mechanism into a dynamic, adaptable system. The locking blade can engage at multiple positions along the shaft, allowing the mechanism to be optimized for different load conditions and operational requirements, thereby reducing operating effort while maintaining reliability.
Solution Approach 2:
The locking mechanism is divided into separable components: the shaft, locking blade, position pin, and adjusting nut. This segmentation allows each component to be optimized independently and enables easier maintenance and adjustment, reducing overall operational difficulty while preserving locking reliability.
3Adaptability or versatility
If ARLM with adjustable shaft and locking blade is used, then the adjustment ability and load capacity are increased, but the device complexity increases
Solution Approach 1:
The shaft serves multiple functions: it acts as the primary locking element, provides adjustment capability through angular positioning, and enables load bearing through the locking blade engagement. This multi-functionality reduces the need for separate components, thereby increasing adaptability and load capacity without proportionally increasing overall device complexity.

AI summary
The ANGULAR ROTATION LOCKING MECHANISM (ARLM) is used on cargo transport vehicles such as trucks and ships. The structure has a large load capacity, the ability to open and close easily, flexibly, but ensures the ability to lock the brake during the transport of the vehicle, in all weather conditions. Because of a purely mechanical structure, the maintenance and repair process is simple. The main point of the design is the self-positioning between the front pedestal shaft and the locking blade during operation.
