Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer systems face challenges in accurately detecting the position of objects being transferred by mobile bodies, especially in crowded or complex environments, leading to potential collisions between the mobile body and the object or other objects.
Innovation Solution
A transfer system that includes a mobile body equipped with a detection object mounted at a higher position than the object, and a first detecting part also located at a higher position, which uses laser rangefinders to accurately detect the position of the object, allowing for precise control and navigation of the mobile body to avoid obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mobile body transfers an object in a crowded or complex environment, then the transfer operation can be performed, but accurate detection of the object position becomes difficult leading to potential collisions
Solution Approach 1:
The patent applies dimensionality change by mounting the detection object and first detecting part at higher positions (vertical dimension) than the object being transferred. This elevated positioning allows the detecting part to detect the detection object from above, avoiding occlusion by the object itself or other obstacles in the horizontal plane, thereby achieving accurate position detection in crowded environments
Solution Approach 2:
The patent introduces a detection object as an intermediary element mounted on the object being transferred. This detection object serves as a mediator between the mobile body's detecting part and the actual object, enabling indirect detection of the object's position through the detection object, which improves detection accuracy without requiring direct line-of-sight to the object itself
2Measurement precision
If the detection object and detecting part are mounted at higher positions, then position detection accuracy is improved, but the device structure becomes more complex
Solution Approach 1:
The detection object mounted at the higher position serves multiple functions: it acts as a reflective target for the detecting part, provides a stable mounting point for detection, and can serve as a reference marker for positioning. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while maintaining improved detection accuracy
