Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer systems face challenges in accurately detecting the position of objects being transferred by mobile bodies, particularly in crowded or complex environments, leading to potential collisions between the mobile body and the object or other obstacles.
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 higher than the object, which uses laser rangefinders to accurately detect the position of the object, allowing the control device to generate a movement plan and avoid obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detection object and detecting part are positioned at higher positions, then the position detection accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent positions the detection object and detecting part in the vertical dimension (higher position) to achieve better line-of-sight detection accuracy. This dimensional change allows the system to detect objects above the mobile body without interference from surrounding obstacles, resolving the contradiction by using spatial dimensionality to improve measurement precision while maintaining reasonable device complexity.
2Productivity
If the mobile body travels in crowded environments, then the productivity is improved, but the collision risk increases
Solution Approach 1:
The patent replaces mechanical collision avoidance with optical detection. By using laser rangefinders and detection objects positioned at higher locations, the system optically detects and tracks objects in crowded environments, enabling the mobile body to navigate efficiently without physical collisions. This substitution of mechanical interaction with optical sensing resolves the contradiction between productivity and collision risk.
