Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices, such as smartphones, require two hands to operate due to their design, making them less functional, less portable, and less ergonomic, and users face challenges in managing multiple data sources and information streams with complex and inflexible user interfaces that lack single-hand operation capabilities.
Innovation Solution
A wearable ring-type holder with a computer interface trackpad and optical detection system that allows single-hand operation by tracking markers on the user's thumb or finger, enabling efficient control over multiple data sources and devices, including touch-sensitive display screens with a graphical user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional smartphone design is used, then device functionality is comprehensive, but device requires two hands to operate reducing portability and ergonomics
Solution Approach 1:
The device is segmented into modular components: a wearable ring-type holder that can be worn on the finger, a display portion that can be detached or repositioned, and a base portion with computational components. This segmentation allows the core computing functionality to be worn on one hand while maintaining access to comprehensive device features through wireless connectivity and modular reconfiguration.
Solution Approach 2:
The patent transitions from traditional two-dimensional handheld operation to three-dimensional wearable operation. The ring-type holder enables the device to be worn on the finger, utilizing the third dimension (depth/wearability) to free up hands while maintaining operational capability through spatial reconfiguration of display and input elements.
2Weight of moving object
If device size is reduced for portability, then device can be worn on finger, but user interface becomes harder to operate
Solution Approach 1:
The device incorporates dynamic, adjustable components including a repositionable display portion that can move between different locations relative to the ring holder, and adjustable ring sizes to fit different finger dimensions. This dynamic adaptability allows the interface to be optimized for operational comfort while maintaining minimal weight for wearability.
Solution Approach 2:
The ring-type holder serves multiple functions: it acts as the device housing, mounting structure for the display, adjustable size adapter for different fingers, and potential input interface itself. This multi-functionality consolidates what would traditionally require separate components into a single wearable unit, maintaining operability despite size constraints.
3Adaptability or versatility
If complex interface is used to manage multiple data sources, then information management capability is enhanced, but interface complexity increases making it harder to use
Solution Approach 1:
The wearable device acts as an intermediary between the user and multiple data sources. The ring-type holder with its sensors, display, and computational capabilities serves as a centralized mediation point that can monitor, manage, and present information from multiple sources (smartphone, tablet, computer, sensors) without requiring the user to directly interact with each source's complex interface.
Solution Approach 2:
The device incorporates sensors and automated monitoring capabilities that enable self-service functionality. The system can automatically detect user needs, monitor physiological data through integrated sensors, and manage information streams without requiring complex manual configuration, thereby simplifying the interface while maintaining advanced information management capabilities.

Data Source
AI summary
A finger-wearable computing device may comprise a processor, a ring base, and a display screen. The display screen is coupled to the ring base and coupled to the processor to display an output. The display screen includes a command area configured to receive user input from a wearer's thumb while the finger-wearable computing device is worn on a wearer's finger. The ring base may be resiliently flexible and may define an overlapping loop with a central opening that expands and contracts to fit the wearer's finger. The display screen may be flexibly coupled to the ring base and may have a vertical axis that is canted at an angle relative to a central axis of the ring base to ergonomically position the display screen while the wearable computing device is worn on the finger of the wearer's hand.
