Lifting Platform Misalignment Detection via Intermediary Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lifting platforms lack reliable monitoring systems to ensure the accurate alignment and stability of objects being lifted, leading to potential detachment and associated risks of damage and injury.
Innovation Solution
A monitoring device is integrated with a lifting platform, featuring a support non-rotatably connected to the object, a fastening device on the support arm, and sensors to detect relative movement, position, and pressure changes, with an evaluation system to output signals if limit values are exceeded, preventing detachment and ensuring safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless spirit levels are attached to the object being lifted to detect tilt, then protection against uneven movement is improved, but reliability is insufficient when lifting arms are incorrectly attached to angled components
Solution Approach 1:
A support element is introduced as an intermediary between the object being lifted and the sensor. The support is non-rotatably connected to the object and moves with the object, while the sensor remains fixed to the support arm. This intermediary structure allows the sensor to detect relative movement between the support arm and the object, providing reliable detection even when the object has angled components that would confuse a spirit level attached directly to the object.
2Reliability
If sensors are added to monitor alignment and position, then safety and reliability are improved, but device complexity increases
Solution Approach 1:
The monitoring function is segmented into two independent parts: a support element that moves with the object and a fixed sensor on the support arm. This segmentation allows the sensor to remain simple and fixed while the support element carries all the complexity of adapting to the object's position and orientation. The relative movement between these segmented parts provides the monitoring capability without complicating the sensor itself.
Solution Approach 2:
The support element serves multiple functions: it provides a mounting point for the sensor, moves with the object to maintain relative position, and its relative movement to the support arm automatically provides the detection signal. This self-service approach reduces the need for additional complex mechanisms while achieving reliable alignment monitoring.
3Measurement precision
If the support is firmly attached to prevent rotation, then measurement accuracy is improved, but adaptability to different object configurations is reduced
Solution Approach 1:
The support element is designed to be dynamically adaptable - it can be non-rotatably connected to accommodate various object configurations while maintaining its ability to move with the object. The support may be detachably connectable or gravitationally supported, allowing it to adapt to different object shapes and positions while preventing rotation relative to the object. This dynamic design maintains measurement precision across different scenarios.
