Magnetic Opening Structure for Detachable Device Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices with detachable bodies, such as notebooks and tablets, face issues with elastic fatigue and damage from friction, leading to instability in the locking mechanism, as traditional elastic elements and internal ramp structures fail to maintain effective fixation and ease of opening over time.
Innovation Solution
A magnetic opening structure featuring a first and second magnetic component with poles, where the second pole attracts and the third pole repels the first pole, allowing the second body to pivot around an axis, enabling secure locking and easy unlocking by rotating a knob, thus avoiding elastic fatigue and friction-induced instability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic elements and hooks are used to fix the two bodies, then the two bodies can be detached and fixed, but the elastic element easily abrades and loses fastening ability after long-term use
Solution Approach 1:
The patent replaces the traditional mechanical elastic element and hook system with a magnetic locking mechanism. The magnetic component generates magnetic attraction force to hold the first and second bodies together, eliminating the need for elastic elements that undergo repeated deformation and eventually fatigue. This substitution of mechanical elastic deformation with magnetic field interaction resolves the contradiction by providing a non-contact force that does not degrade through use.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the locking part and the locking groove. Instead of direct mechanical contact between elastic elements and hooks, the magnetic field acts as a mediator to transmit the holding force. The magnetic component creates a magnetic attraction force that acts through space to secure the bodies, reducing wear and extending service life while maintaining reliability.
2Stability of the object's composition
If internal ramp structure in the hinge is utilized to make force applied on opening position different with different opening angles, then the screen can be stably fixed, but the internal ramp structure is easily damaged when the applied force abrades the ramp
Solution Approach 1:
The patent replaces the mechanical ramp structure with a magnetic locking mechanism. The magnetic component interacts with the locking groove through magnetic attraction without requiring sliding contact or ramp surfaces. This eliminates the friction and abrasion that damage traditional ramp structures while maintaining the ability to provide stable fixation at different opening angles through magnetic force control.
Solution Approach 2:
The patent extracts and removes the harmful ramp structure from the hinge mechanism. By eliminating the ramp component entirely and replacing it with a magnetic locking system, the source of friction damage is removed. The magnetic component can engage with the locking groove without sliding contact, preventing the wear and damage that occurs in traditional ramp-based hinges.
3Ease of operation
If traditional elastic hook is used to fix the covering body and the accommodated body, then the two bodies can be connected, but the hook may not return to the original position because of elastic fatigue
Solution Approach 1:
The patent replaces the elastic hook mechanism with a magnetic locking system. The magnetic component provides consistent magnetic attraction force to return the cover to its closed position without relying on elastic deformation. This eliminates elastic fatigue and ensures the cover reliably returns to its original position, maintaining both ease of operation and position stability over extended use.

AI summary
A device having an opening structure includes a first body having a first locking part, a second body having a second locking part, a first magnetic component, and a second magnetic component. The second body has a closing position and an unlocking position relative to the first body. The first body overlaps the second body when the second body is located at the closing position. The first locking part separates from the second locking part when the second body is located at the unlocking position. The first magnetic component has a first pole fixed to the first locking part. The second magnetic component has a second pole and a third pole. The second pole attracts the first pole, and the third pole repels the first pole. The second pole is pivoted on the second body around an axis.
