Lead Component Release Height for Pre-Loaded Board Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to prevent interference between a held component and a pre-loaded component on a board when mounting the held component, as existing technologies do not effectively calculate the release position to avoid such interference.
Innovation Solution
A calculation device for a work machine is developed, which includes a holding tool and a moving device to calculate the release position of the held component, determining the height at which the held component is released by the holding tool to insert the lead into a board hole without interfering with pre-loaded components, based on the dimensions of the pre-loaded component, the lead, and the holding tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the holding tool holds the held component at a low position to insert the lead into the hole, then the lead can be inserted into the hole, but the body of the held component interferes with the pre-loaded component
Solution Approach 1:
The patent introduces a vertical height dimension (Z-axis) to resolve the horizontal interference problem. By calculating and adjusting the release height of the held component, the body is positioned at a sufficient height above the pre-loaded component, allowing the lead to be inserted into the hole without the body interfering with the pre-loaded component.
Solution Approach 2:
The patent performs preliminary calculation of the release height before the actual insertion operation. The calculation device computes the required height based on the dimensions of the pre-loaded component, the held component, and the holding tool, ensuring that when the held component is released, it is already at the correct height to avoid interference during insertion.
2Object-affected harmful factors
If the holding tool releases the held component at a high position to avoid interference with pre-loaded component, then interference is prevented, but the lead cannot be inserted into the hole
Solution Approach 1:
The patent uses the vertical dimension to decouple the two requirements: the release height is set high enough to prevent horizontal interference with the pre-loaded component, while the lead length is sufficient to reach from this elevated position down into the hole, thus satisfying both conditions simultaneously.
3Ease of operation
If the held component is mounted directly without calculating release height, then the mounting process is simple, but interference with pre-loaded component occurs
Solution Approach 1:
The patent introduces a calculation device as an intermediary between the design parameters and the mounting operation. This device automatically computes the precise release height based on component and tool dimensions, eliminating the need for manual judgment or trial-and-error while preventing interference.
Solution Approach 2:
The calculation of release height is performed in advance before the actual mounting operation, allowing the system to plan the precise release position that avoids interference, thus making the subsequent mounting operation straightforward and interference-free.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution prevents interference by calculating the release height for the held component, allowing it to be released and inserted into the board hole without contacting pre-loaded components, ensuring accurate mounting and avoiding interference.
Implementation Method 1
the held component descends on its own weight or the like in a state of the body of the held component being separated from the board
