Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional embroidery frames secured by magnetic attraction can cause uncontrollable snapping during assembly and disassembly, posing a safety risk, especially for operators with limited strength or dexterity, as the magnetic force can lead to injury.
Innovation Solution
The embroidery frame features a multicomponent top section with an alignment component and a retention component, utilizing magnetic attachment and a hinged motion with alignment pins and slots to control the assembly and disassembly process, allowing for safer and easier handling through a detachable handle for mechanical advantage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic attraction is used to secure the top section to the bottom section, then the frame can be easily assembled and disassembled, but the magnetic force can cause uncontrollable snapping and injury during assembly and disassembly
Solution Approach 1:
The top section is divided into two separate components: an alignment component and a retention component. The alignment component first attaches to the base section via magnetic attraction, and then the retention component is engaged with the alignment component. This segmentation allows the magnetic force to be applied in controlled stages rather than all at once, preventing uncontrollable snapping while maintaining ease of operation.
Solution Approach 2:
The alignment component performs a preliminary attachment to the base section before the retention component is fully engaged. This preliminary action positions the retention component correctly and allows the operator to maintain control throughout the assembly process, preventing the sudden snapping that occurs when the entire top section attaches at once.
2Strength
If strong magnetic force is used to secure the top section to the bottom section, then the frame is securely held together, but the operator cannot generate enough force to separate the sections while maintaining control
Solution Approach 1:
By dividing the top section into alignment and retention components, the magnetic holding force is distributed across two separate engagement steps. The retention component can be disassembled by rotating it away from the alignment component, which breaks the magnetic connection in a controlled manner rather than requiring direct pulling against the full magnetic force.
Solution Approach 2:
The retention component is designed to rotate about the alignment component during assembly and disassembly. This rotational motion transforms the disassembly action from a direct pull against strong magnetic force into a controlled rotational movement that gradually breaks the magnetic connection, making it easier to separate while maintaining control.
3Reliability
If a multicomponent top section with alignment and retention components is used, then control over magnetic forces is enhanced and safety is improved, but the device complexity increases
Solution Approach 1:
The alignment component and retention component are designed to work together as an integrated system. The retention component engages with the alignment component through slots and pintles, creating a unified assembly that functions as a single top section during embroidery operations, thus minimizing the practical impact of the additional component while maintaining safety benefits.

Function Achieved in This Case
This design reduces the effort required for assembly and disassembly, enhances control over the magnetic forces, and minimizes the risk of injury by allowing precise alignment and controlled movement of the retention section relative to the alignment section, providing a safer and more manageable operation.
Implementation Method 1
The alignment component is configured to be magnetically attached to and aligned with the base section in a first step
Implementation Method 2
the retention component is moved relative to the alignment component such that the retention component is magnetically attached to the base section
