Magnetic Holding Device with Horizontal Shielding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic holding devices have a large volume and height due to vertical guiding passages, making them cumbersome for storage and transportation.
Innovation Solution
A compact magnetic holding device design featuring a receptacle with a chamber, an attracting device, and a shielding device that allows the magnetic elements to be shielded or unshielded without vertical movement, using a pulley and spindle system to manage the shielding device's position, reducing the device's overall height and volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vertical guiding passages are provided in the outer container to allow magnetic elements to move up and down, then the magnetic holding device can effectively attract and release work pieces, but the outer container requires a large height and volume that is adverse for storage and transportation
Solution Approach 1:
The patent transitions from vertical movement (one dimension) to horizontal movement (another dimension) by providing guiding passages in the horizontal direction within the platform, allowing magnetic elements to move laterally between the attracting device and the bottom portion without requiring vertical space, thus reducing device height and volume while maintaining magnetic holding functionality
Solution Approach 2:
The patent nests the guiding passages within the platform structure itself, incorporating the horizontal guiding channels into the platform's internal geometry rather than requiring separate external guiding structures, which optimizes space utilization and reduces overall device volume
2Volume of moving object
If the magnetic holding device is designed with a compact configuration, then storage and transportation efficiency is improved, but the device complexity and manufacturing difficulty may increase
Solution Approach 1:
The patent makes the platform serve multiple functions: it acts as both the supporting structure for the attracting device and as the guiding mechanism for magnetic element movement through integrated horizontal guiding passages, eliminating the need for separate guiding structures and simplifying the overall device architecture
Solution Approach 2:
The patent combines the platform structure with the guiding mechanism into a single integrated component, merging the supporting function and the guiding function into one structural element, which reduces the number of parts and simplifies manufacturing while achieving compact dimensions
Applied Scientific Principles
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 enables a reduced height and volume configuration, simplifying manufacturing and reducing costs while maintaining the ability to attract and release work pieces effectively, improving storage and transportation efficiency.
Implementation Method 1
a magnetic shielding member provided thereon and slidable and moveable through the space that is formed between the bottom portion of the receptacle and the attracting device, and the attracting device is shielded and prevented from attracting the work piece when the magnetic shielding member of the shielding device is located between the bottom portion of the receptacle and the attracting device
Implementation Method 2
the attracting device is capable of attracting a work piece when the non-shielding element of the shielding device is located between the bottom portion of the receptacle and the attracting device
