Magnetic Locking Assembly for Laptop Display Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing devices with multiple modes of operation, such as laptops and tablets, often fail to transition effectively between modes and may be damaged due to contact between the base member and the display member, leading to issues like scuffing and instability.
Innovation Solution
A locking assembly is introduced, comprising a spring, magnetic members, a wheel, and a lock, which allows the computing device to be smoothly transitioned between various positions in tablet mode while locking in desired positions, reducing scuffing by preventing the display member from dragging along the base member, and providing additional stability through magnetic forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display member is allowed to move freely between positions, then ease of operation is improved, but stability deteriorates due to unintended movement and scuffing
Solution Approach 1:
The locking assembly is activated in advance by rotating the display member to a desired position, which triggers the wheel to engage with the lock mechanism. This preliminary engagement ensures the display member is securely held before any unintended movement can occur, while still allowing smooth transitions when intentionally moved.
Solution Approach 2:
The wheel acts as an intermediary element between the display member and the lock mechanism. It transfers the rotational motion of the display member to the lock, enabling controlled engagement and disengagement. This intermediary mechanism allows smooth transitions while preventing unintended movement through precise mechanical control.
2Stability of the object's composition
If magnetic members are added to provide stability, then stability is improved, but device complexity increases
Solution Approach 1:
The patent replaces part of the purely mechanical locking system with magnetic members that provide holding force. The magnetic field substitutes for some mechanical components, reducing the need for complex mechanical springs and latches while maintaining stable positioning. This hybrid approach simplifies the overall device complexity.
Solution Approach 2:
The magnetic members allow for adjustable magnetic field strength to control the holding force. By changing the magnetic parameter (field strength), the system can provide sufficient stability without requiring overly complex mechanical structures. The magnetic force can be tuned to match the weight and dimensions of the display member.
3Reliability
If a locking mechanism is implemented to prevent scuffing, then reliability is improved, but ease of operation deteriorates due to additional locking steps
Solution Approach 1:
The locking mechanism is designed to be dynamic rather than static. The wheel and lock engagement automatically adjusts based on the position and movement of the display member. When the display member is intentionally moved, the mechanism dynamically disengages; when stationary, it automatically engages to prevent scuffing. This dynamic behavior eliminates the need for manual locking steps.
Solution Approach 2:
The locking assembly is self-activating through the rotation of the display member itself. As the user rotates the display member to a desired position, the wheel automatically engages with the lock mechanism without requiring any additional action from the user. The system serves itself by using the user's intended movement to trigger the locking action, thereby protecting against scuffing while maintaining ease of operation.

Function Achieved in This Case
The locking assembly enables seamless transitions between laptop and tablet modes, reduces scuffing, and enhances stability by ensuring the display member remains securely positioned, preventing unintended movement unless a sufficient force is applied.
