Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic apparatus using magnetic attraction forces for assembly faces challenges with high disassembly time costs and potential misalignment issues due to strong magnetic forces, leading to complications in the assembly process.
Innovation Solution
The design incorporates a first body with magnetic elements and a second body with receiving grooves and assistant magnetic elements, where the magnetic attraction between assistant and second magnetic elements keeps the moving assembly fixed until alignment, allowing the stronger magnetic force between the first and second magnetic elements to drive the assembly towards alignment, providing an auxiliary combination effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a magnet with stronger magnetic attraction force is used to tightly combine different parts, then the combination strength is improved, but the risk of dislocation during assembly increases due to attraction before alignment
Solution Approach 1:
The magnetic elements are segmented into two functional groups: first magnetic elements on the first body for strong attraction, and second magnetic elements on movable assemblies for controlled interaction. This segmentation allows different magnetic forces to serve different purposes in the assembly process.
Solution Approach 2:
The receiving grooves are preliminarily designed with specific geometries and positions to guide the movable assemblies into correct alignment before the strong magnetic attraction takes effect. This preliminary structural arrangement prevents dislocation by establishing alignment constraints prior to final magnetic bonding.
2Strength
If bolts are used to combine different parts during assembly, then the combination strength is improved, but the assembly time and disassembly time increase
Solution Approach 1:
The traditional mechanical bolted connection system is replaced with a magnetic field-based attraction system. The magnetic elements provide sufficient holding force without requiring mechanical fasteners, enabling faster assembly and disassembly operations while maintaining combination strength.
Solution Approach 2:
The magnetic force parameters are optimized to provide adequate attraction strength for part combination while allowing for easy separation when needed. By controlling the magnetic field strength and distribution, the system achieves both strong bonding during assembly and convenient disassembly, eliminating the time penalty associated with bolted connections.
3Productivity
If magnetic elements are disposed on different parts to achieve auxiliary combination effect, then the assembly speed is improved, but the occurrence of dislocation during assembly increases
Solution Approach 1:
The second magnetic elements on the movable assemblies act as intermediaries between the external magnetic attraction and the movable components themselves. These intermediary elements allow the magnetic force to be applied in a controlled manner, enabling fast assembly while preventing direct dislocation of the main parts through the receiving groove geometry.
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
This solution reduces dislocation occurrences and simplifies the assembly process by ensuring precise alignment and efficient combination of parts using a controlled magnetic attraction force, thereby reducing assembly time and costs.
Implementation Method 1
The magnetic attraction force between the assistant magnetic element and the second magnetic element is smaller than that between the first magnetic element and the second magnetic element
Implementation Method 2
When the second combination side of the second body is combined with the first combination side of the first body, each second magnetic element is attracted by each first magnetic element to break the attraction with the assistant magnetic element, such that each moving assembly can move toward the second combination side

AI summary
An electronic apparatus combined with a magnetic attraction force includes a first body and a second body. The first body includes at least one first magnetic element, and the second body includes at least one receiving groove, at least one moving assembly, and at least one assistant magnetic element. Each moving assembly is movably disposed in each receiving groove, and each moving assembly includes a second magnetic element. Each assistant magnetic element is fixed in the receiving groove, and the magnetic attraction force between the assistant magnetic element and the second magnetic element is smaller than that between the first magnetic element and the second magnetic element. When the second body is combined with the first body, each second magnetic element is attracted by each first magnetic element, such that each moving assembly is driven to move toward the first body.
