Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work machines face inefficiencies in picking up components when other components interfere, leading to reduced pickup efficiency due to overlapping or adjacent positions.
Innovation Solution
A work machine equipped with a pickup member, storage device for positional information, and a recognition device that selects a pickup position less likely to interfere with other components based on optical recognition, allowing efficient component retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single pickup position is selected for component retrieval, then the pickup process is simple and fast, but the pickup fails when other components interfere with the target component
Solution Approach 1:
The pickup position is divided into multiple candidate positions (first pickup position, second pickup position, etc.) around the target component. Instead of using a single pickup position, the system segments the pickup location into multiple options and selects the most appropriate one based on the spatial relationship with adjacent components, thereby avoiding interference while maintaining efficient pickup.
2Reliability
If multiple pickup positions are considered to avoid interference, then the pickup success rate improves, but the selection process becomes more complex and time-consuming
Solution Approach 1:
The system performs preliminary recognition of the target component and its adjacent components before pickup. By advance identifying the spatial relationships and potential interference, the control device can pre-determine the appropriate pickup position from multiple candidates, avoiding complex real-time decision-making during the actual pickup process.
Solution Approach 2:
The patent replaces complex mechanical trial-and-error pickup attempts with an intelligent selection system. The control device uses recognition results and predetermined positional information to automatically select the optimal pickup position, substituting mechanical complexity with computational logic based on spatial relationships between components.
3Ease of operation
If the pickup member attempts to pick up a component at its center position, then the pickup process is straightforward, but interference from adjacent components prevents successful pickup
Solution Approach 1:
Instead of always picking up the target component at its center position, the system adjusts the pickup location based on local conditions. When adjacent components are present, the pickup position is shifted to a location that avoids interference while still effectively grasping the target component. This local adaptation ensures both operational simplicity and pickup success.

AI summary
A work machine includes a pickup member configured to pick up a component; a storage device configured to store positional information on multiple pickup positions where the pickup member can pick up the component; a recognition device configured to optically recognize a multiple of the component including the pickup target; and a control device configured to select, from the multiple pickup positions of the pickup target component, one pickup position which is less likely to interfere with other components based on the positional information and a recognition result from the recognition device, and cause the pick member to pick up the pickup target component at the one selected pickup position.
