Rotating Locking Member for Reliable Wearable Accessory Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accessory devices for electronic devices lack convenience and reliability in connection and detachment processes, particularly for wearable devices.
Innovation Solution
An accessory device featuring a housing with a rotatable locking member and a holder that includes an insertion groove and protrusions for secure attachment and detachment, utilizing a first and second rotation direction to fix the holder and locking member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple attachment mechanism is used, then ease of operation is improved, but connection reliability deteriorates
Solution Approach 1:
The locking member is designed to rotate between locked and unlocked positions, transforming a static connection into a dynamic one that can be easily adjusted while maintaining secure connection when locked
Solution Approach 2:
The pressing region automatically rotates the locking member to the locked position when the holder is inserted, eliminating the need for manual locking operations while ensuring reliable connection
2Reliability
If a rotatable locking member with multiple protrusions is used, then connection reliability is improved, but device complexity increases
Solution Approach 1:
Multiple functional elements (locking mechanism, positioning features, and automatic engagement components) are merged into a single integrated locking member that rotates to achieve locked state, reducing overall structural complexity while maintaining reliability
Solution Approach 2:
The locking member serves multiple functions: it provides locking through rotation, positions the holder through protrusions, and enables automatic engagement through the pressing region, eliminating the need for separate mechanisms

AI summary
An accessory device according to an embodiment may include: a housing; a locking member having an insertion groove and accommodated in the housing to be rotatable about a rotary shaft in a first rotation direction or a second rotation direction opposite to the first rotation direction; and a holder having an insertion region inserted into the insertion groove. The locking member may further comprise a first protrusion and a second protrusion respectively extending from both sides of the insertion groove. The holder may further comprise a pressing region which, when the insertion region is inserted into the insertion groove, rotates the locking member in the first rotation direction by pressing the first protrusion, and a protrusion groove into which the second protrusion is inserted when the locking member rotates in the first rotation direction, to fix the holder and the locking member.
