Rotary Locking Member Assembly for Easy Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accessory devices for electronic devices, such as wearable devices, often have complex structures that complicate the process of attaching and detaching, leading to inconvenience and reduced wearability.
Innovation Solution
An accessory device featuring a housing with a receiving groove and a rotatable axis member, a lever, a locking member, and an elastic member, which simplifies the attachment and detachment process by allowing the locking member to move in response to the rotation of the axis member, facilitated by inclined surfaces and compression of the elastic member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex structure is used in accessory devices to ensure secure attachment, then reliability is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The locking mechanism is divided into separate functional components: a locking member with pin region for engagement, an axis member for rotation, and an elastic member for providing force. This segmentation allows each component to perform its specific function independently, achieving reliable attachment through coordinated action of simple parts rather than a complex integrated structure.
Solution Approach 2:
The locking member is designed to be movable rather than fixed, allowing it to transition between locked and unlocked states. The elastic member provides dynamic force that can be compressed and restored, enabling the locking mechanism to adapt to attachment and detachment operations while maintaining security when engaged.
2Reliability
If a complex locking mechanism is used to ensure secure attachment, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The locking member transitions from a static to a dynamic state through rotation of the axis member. This dynamic mechanism allows the locking member to move between engaged and disengaged positions, providing secure attachment when locked while enabling easy operation through simple rotational input that automatically triggers the locking action.
Solution Approach 2:
The elastic member automatically provides the force needed to engage the locking member with the pin groove without requiring additional user action. The system serves itself by using the elastic force to maintain engagement, reducing the operational steps needed for secure attachment while ensuring reliable locking.
3Adaptability or versatility
If multiple components are used to achieve attachment function, then adaptability is improved, but device complexity increases
Solution Approach 1:
The locking member serves multiple functions: it engages with the pin groove to provide attachment, moves in response to axis member rotation to enable detachment, and works with the elastic member to provide securing force. This multi-functionality is achieved through a single component design rather than requiring separate mechanisms for each function, reducing overall device complexity.
Solution Approach 2:
The locking mechanism merges the attachment function, the locking action, and the securing force into an integrated system of three components that work together. The locking member combines the engagement feature (pin region) with the movement capability, while the elastic member combines the force provision with the restoration function, achieving versatile attachment capability through consolidated design.
