Magnetic Stylus Fastener for Secure Touch Device Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stylus fastening mechanisms for touch electronic devices often clamp the stylus too tightly, making it difficult to place and take, and can result in the stylus falling off, affecting user experience.
Innovation Solution
A support apparatus with a magnetic stylus fastener that uses a magnet with opposing poles to generate a magnetic acting force, allowing for secure fastening without clamping too tightly, enabling easy placement and retrieval of the stylus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stylus is clamped tightly using traditional fastening structures, then the stylus is securely fastened and prevented from falling off, but it becomes difficult to place and take the stylus
Solution Approach 1:
The patent replaces the traditional mechanical clamping system with a magnetic field-based fastening system. The magnet embedded in the stylus interacts with the magnetic stylus fastener on the support apparatus, generating magnetic attraction force that secures the stylus without requiring mechanical clamping structures. This substitution eliminates the need for tight mechanical constraints while maintaining secure fastening.
Solution Approach 2:
The patent changes the fastening mechanism from mechanical force to magnetic force parameters. By adjusting magnetic field strength and polarity configuration (N pole and S pole arrangement), the system achieves optimal balance between holding force and ease of removal. The magnetic interaction allows the stylus to be securely held during use but easily detached when needed, resolving the contradiction between reliability and ease of operation.
2Reliability
If a stylus is clamped too tightly, then the stylus is securely fastened, but it may fall off due to excessive force
Solution Approach 1:
The patent replaces mechanical clamping with magnetic attraction, eliminating the harmful effect of excessive mechanical force that causes the stylus to fall off. The magnetic field provides a distributed attractive force that secures the stylus gently but firmly, preventing the concentration of force at specific clamping points that leads to detachment.
Solution Approach 2:
The magnetic field acts as an intermediary between the stylus and the support apparatus, mediating the fastening interaction. Instead of direct mechanical contact and force transmission, the magnetic field transmits the attractive force uniformly, preventing the stylus from falling off while avoiding the harmful effects of excessive mechanical clamping.
3Reliability
If traditional fastening structures are used, then the stylus can be fastened, but additional operation is required to re-fasten it after removal
Solution Approach 1:
The magnetic fastening system enables self-service functionality. When the stylus is brought near the support apparatus, the magnetic attraction automatically pulls it into the correct position and secures it without requiring manual alignment or additional fastening operations. The system performs the fastening action automatically through magnetic attraction, eliminating the need for user intervention to re-fasten the stylus after removal.
