Solution Overview

Problem

Smart rings face challenges such as needing to be removed for charging, poor fit, limited functionality, and lack of user interactivity.

Innovation Solution

A smart ring configured with a removable power source and an internal power source, where the removable power source can be detached for charging or replaced, and is disposed at the band-shaped housing's outer surface, allowing it to charge the internal power source and enable various power modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the smart ring uses an internal power source only, then the device can be worn continuously, but the battery capacity is limited and requires frequent removal for charging

Engineering Contradiction:

Improvebattery capacityVSAvoidcharging convenience

Core Design Contradiction:

Duration of action of moving objectVSEase of operation

Solution Approach 1:

The power source is divided into two independent parts: an internal power source integrated into the ring and an external removable power source. The external power source can be detached and attached to charging surfaces in the environment, allowing the ring to be worn continuously while enabling convenient charging without removal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

An external removable power source acts as an intermediary between the ring's internal power source and environmental charging surfaces. This intermediary component transfers energy from environmental sources to the internal power source, enabling indirect charging while the ring remains on the user's finger.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the smart ring includes multiple components for sensing, communication, and user interface, then functionality is enhanced, but power consumption increases

Engineering Contradiction:

ImprovefunctionalityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts power modes based on the presence and state of the external power source. When the external power source is attached and charging, the system can operate in higher-power modes with enhanced functionality. When charging is not available, the system transitions to lower-power modes to conserve battery life.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the smart ring design is compact and fits tightly on the finger, then wearability is improved, but space for power sources and components is limited

Engineering Contradiction:

ImprovewearabilityVSAvoidpower source capacity

Core Design Contradiction:

Ease of operationVSVolume of stationary object

Solution Approach 1:

The power source capacity is extracted from the ring structure itself and placed in a separate external removable component. This extraction allows the ring to maintain a compact, wearable form factor while the external power source provides additional capacity that would be impossible to accommodate within the ring's limited volume.

Inventive Principle:

Principle #2Taking out (Extraction)
