Forklift Path Monitoring With Dynamic Sensor Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial trucks with static monitoring systems often stop unnecessarily or prematurely due to varying braking distances influenced by speed and load weight, leading to inefficiencies in operation.
Innovation Solution
A method and industrial truck design where a control device dynamically adjusts the alignment of monitoring devices based on operating parameters like speed, load, and steering angle, allowing for a dynamically monitored route area that optimizes braking distance for safe stopping without early or unnecessary braking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If monitoring sensors are designed for maximum braking distance, then collision prevention is ensured, but unnecessary or premature stopping occurs
Solution Approach 1:
The monitoring area is dynamically adjusted based on current operating parameters (speed, load weight, braking distance). The sensor system changes its detection range and orientation in real-time to match actual braking requirements, transitioning from a static to a dynamic monitoring system that adapts to varying operational conditions.
Solution Approach 2:
The system changes physical parameters of the monitoring area (detection range, orientation angle, monitoring distance) based on operating parameters. When speed or load weight decreases, the monitoring area is reduced accordingly, allowing the truck to operate more efficiently without compromising safety.
2Reliability
If monitoring area is increased to cover maximum braking distance, then safety is improved, but device complexity increases
Solution Approach 1:
Rather than providing a permanently large monitoring area that covers all possible braking scenarios, the system dynamically adjusts the monitoring area size and orientation based on current needs. This dynamic approach maintains safety while reducing the effective complexity of the monitoring system at any given moment.
3Device complexity
If monitoring device orientation is fixed, then device complexity is reduced, but adaptability to varying operating conditions deteriorates
Solution Approach 1:
The monitoring device incorporates adjustable orientation capabilities that allow it to adapt to varying operating conditions. The device can change its viewing angle and detection range dynamically, providing versatility without requiring multiple fixed sensor systems.
