Magnetic Holder with Adjustable Guide for Workpiece Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding frames struggle to securely hold workpieces of varying thickness due to limitations in their design, particularly when the distance between guide pieces is insufficient, leading to instability and potential slippage during use.
Innovation Solution
The holding frame incorporates a unique configuration with a frame forming portion and a holder, where the holder includes first and second holding surfaces that extend in different directions, connected by a connecting portion, allowing for magnetic attachment to the frame forming portion. This configuration enables the frame to securely hold workpieces of varying thickness by adjusting the gap between the holder and the frame based on the thickness of the workpiece, utilizing magnets for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between guide pieces is reduced to accommodate thinner workpieces, then the holder can hold thinner workpieces, but the holder cannot securely hold thicker workpieces
Solution Approach 1:
The holder is designed with movable guide pieces that can shift position relative to each other. The guide pieces are not fixed at a constant distance but can dynamically adjust their spacing to accommodate workpieces of varying thickness while maintaining secure holding through magnetic attraction between the holder and frame side.
Solution Approach 2:
The distance parameter between guide pieces is made variable rather than fixed. By allowing the guide pieces to change their relative position, the holder can adapt to different workpiece thicknesses. The magnetic holding force compensates for the varying distances, maintaining reliable holding across different parameters.
2Device complexity
If the guide pieces are positioned close together, then the holder structure is more compact, but the holder cannot maintain tension on thicker workpieces
Solution Approach 1:
The guide pieces are designed to be movable rather than fixed, allowing the holder to expand or contract based on workpiece thickness. This dynamic structure maintains compactness when not in use while providing sufficient expansion capability to maintain tension on thicker workpieces through the magnetic holding mechanism.
3Stability of the object's composition
If the holder structure is made rigid to maintain stable positioning, then the holder provides stable positioning, but the holder cannot adapt to varying workpiece thicknesses
Solution Approach 1:
The holder incorporates movable guide pieces that can shift position while maintaining overall structural stability. The magnetic attachment between holder and frame side provides a stable base, while the guide pieces dynamically adjust to accommodate different workpiece thicknesses, achieving both stability and adaptability.

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 effectively stabilizes workpieces of different thicknesses, reducing slippage and ensuring secure holding, even when the thickness varies significantly, by allowing the holder to shift and adjust its position relative to the frame, thus maintaining tension and preventing movement during use.

AI summary
In a holding frame, a frame forming portion includes a first holding surface and the second holding surface extending in different directions crossing an area surface of an inner area defined by the frame forming portion. In a state where a holder is magnetically attached to the frame forming portion, the first holding surface and the second holding surface respectively face inner surfaces of a first holding portion and a second holding portion of the holder. The first holding surface includes a first portion connected to a first connecting portion, and a first end located opposite from the first portion. The second holding surface includes a second portion connected to the first connecting portion, and a second end located opposite from the second portion. A distance between the first end and the second end is greater than a distance between the first portion and the second portion.
