Earbud Charging Case Shell With Adjustable Magnetic Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earphone charging compartment protective cases either lock too tightly, making them difficult to unlock, or too loosely, failing to provide effective protection, due to issues with magnetic attraction or buckle members.
Innovation Solution
A storage device with a first and second protective shell, incorporating a locking member and an auxiliary unlocking member that allows for adjustable locking force through magnetic attraction and sliding mechanisms, enabling easy unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If magnetic attraction members or buckle members are used to achieve locking function, then the protective case can provide locking function, but the locking force is either too large making unlocking difficult or too small making protection ineffective
Solution Approach 1:
The patent applies the dynamics principle by making the locking force adjustable rather than fixed. The first and second protective shells can be locked at multiple positions along the shell surface, allowing the locking force to be dynamically changed between strong (when shells are tightly enclosed) and weak (when shells are slightly separated). This resolves the contradiction by enabling the system to provide strong locking when needed while allowing easy unlocking when the shells are slightly apart.
Solution Approach 2:
The patent changes the parameter of locking force from a fixed value to a variable that can take multiple values. By allowing the protective shells to lock at different positions along the shell surface, the locking force parameter can be adjusted between strong and weak states. This enables the system to overcome the contradiction between providing sufficient locking force and maintaining ease of unlocking.
2Shape
If the protective case has smooth and rounded appearance, then it is aesthetically pleasing, but it increases the difficulty of unlocking
Solution Approach 1:
The patent applies segmentation by dividing the locking function into multiple discrete locking positions along the shell surface. Instead of relying on a single locking point that would require complex mechanisms, the system provides multiple locking positions, allowing the user to select different positions for locking and unlocking. This segmentation approach maintains the smooth appearance while facilitating easier unlocking through multiple accessible positions.
3Reliability
If the locking force is increased to effectively protect the earphone charging compartment, then protection effectiveness is improved, but the protective case becomes locked too tightly making unlocking difficult
Solution Approach 1:
The patent makes the protection effectiveness dynamic by allowing adjustment between strong and weak locking states. When the first and second protective shells are tightly enclosed, the locking force is strong, providing reliable protection. When the shells are slightly separated, the locking force becomes weak, allowing easy unlocking. This dynamic adjustment resolves the contradiction between reliable protection and ease of unlocking.
Solution Approach 2:
The patent applies partial action by providing multiple locking positions rather than requiring full engagement at all positions simultaneously. Users can select partial locking positions that provide sufficient protection while maintaining easier access for unlocking, rather than requiring complete engagement of all locking mechanisms.
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 device provides secure locking and easy unlocking, suitable for small, rounded earphone charging compartments, ensuring effective protection and user convenience.
Implementation Method 1
The locking member includes a plurality of magnets; all the magnets are arranged in the first protective shell and the second protective shell
Implementation Method 2
the auxiliary unlocking member is connected to and is able to drive all the magnets arranged in the second protective shell to slide along a side-by-side distributed direction

AI summary
Disclosed is a storage device, including a first protective shell and a second protective shell for enclosing a peripheral side of an object that needs to be stored, and a locking member and an auxiliary unlocking member. The auxiliary unlocking member is configured to move along a shell surface of the first protective shell or move inside and outside towards the first protective shell to resist a locking force of the locking member. The locking member which can meet the locking and unlocking requirements of two protective shells cooperated with the auxiliary unlocking member which can adjust the locking force or locking state between two protective shells to reduce the difficulty of unlocking two protective shells. Therefore, the storage device can be used to reasonably and effectively store and protect the earphone charging compartment, or other products that are small in size and have a smooth and rounded appearance.
