Rotatable Smart Ring Structure for Intuitive Press-and-Turn Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable devices, such as watches and headsets, often have complex touch screens or numerous keys, making them difficult to operate, and wearable structures like bracelets or rings are primarily decorative, lacking intuitive control mechanisms.
Innovation Solution
A smart ring design featuring a first and second ring body that rotate relative to each other, with a trigger assembly and processing circuit, allowing for intuitive interaction through a pressing operation that converts a trigger signal into an interactive signal, enhanced by magnetic levitation and a flexible printed circuit board with integrated components for control and sensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wearable devices use touch screens or numerous keys, then interaction functions are comprehensive, but operation complexity increases
Solution Approach 1:
The wearable device is segmented into multiple independent control components: a first ring body for basic operations and a second ring body for additional control functions. This segmentation allows each component to have simple, intuitive controls while collectively providing comprehensive interaction capabilities.
Solution Approach 2:
The second ring body is designed to be movable relative to the first ring body, enabling dynamic adjustment of control elements. This dynamic structure allows the device to adapt between different operational modes (rotational control vs. pressing control) based on user needs, maintaining simplicity while expanding functionality.
2Shape
If wearable devices use decorative structures like bracelets or rings, then aesthetic appeal is improved, but control functionality is insufficient
Solution Approach 1:
The ring-shaped structure serves multiple functions simultaneously: it maintains aesthetic appeal as a decorative piece while incorporating control mechanisms (buttons, rotatable sections, touch areas) that provide comprehensive control functionality. The second ring body adds both visual complexity and functional control capabilities.
Solution Approach 2:
The control mechanisms are nested within the ring structure itself. The second ring body is sleeved on the first ring body, creating a nested configuration where control elements are integrated into the decorative form rather than added as separate components.
3Stability of the object's composition
If magnets are used to maintain spacing between ring bodies, then structural stability is improved, but device complexity increases
Solution Approach 1:
The mechanical connection between ring bodies is replaced with magnetic fields. Magnets embedded in both ring bodies create magnetic repulsion or attraction forces that maintain the required spacing and enable controlled movement without physical contact or mechanical linkages, simplifying the overall structure.
Solution Approach 2:
Magnetic fields serve as an intermediary between the two ring bodies, transmitting force and maintaining spacing without direct mechanical contact. This intermediary approach allows for smooth, controlled movement while maintaining stable positioning.

Function Achieved in This Case
The smart ring provides a compact, easy-to-use interface for controlling smart devices with enhanced playability and stability, integrating decoration, interaction, and functionality, while maintaining a small form factor and improving user experience.
Implementation Method 1
the first ring body and the second ring body are spaced apart in the radial direction under mutual magnetic force between the first magnet and the second magnet

AI summary
A smart ring includes: a first ring body provided with a receiving hole; a second ring body, the second ring body movably sleeve on a periphery of the first ring body, and a first gap being formed between the first ring body and the second ring body; a trigger assembly arranged on the first ring body and at least partially exposed from the first ring body; and a processing circuit arranged on the first ring body. The first ring body and the second ring body are capable of rotating with each other, the second ring body is further movable in a radial direction of the smart ring, so as to receive a pressing operation and move toward the first ring body and enable an inner side of the second ring body to abut against a portion of the trigger assembly exposed from the first ring body.
