Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices with fixed sizes may cause sizing issues, leading to improper fit and potential damage when a user's finger becomes stuck, risking harm and affecting physiological data collection quality.
Innovation Solution
The implementation of hinged and gated ring sizing devices with locking mechanisms that allow users to safely remove their fingers by transitioning to an open configuration when a threshold force is exerted, ensuring accurate sizing and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed-size wearable device is used, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The wearable device is divided into two housing components that can be separated from each other. This segmentation allows the device to be assembled in different configurations to accommodate different finger sizes while maintaining consistent internal component positioning, thus resolving the contradiction between manufacturing precision and adaptability.
Solution Approach 2:
The device incorporates a dynamic opening mechanism that allows the housing components to transition between closed and open states. This dynamic capability enables the device to adapt to different user needs during sizing and removal processes, maintaining manufacturing precision while improving adaptability.
2Ease of operation
If a sizing model becomes stuck on a user's finger, then ease of operation deteriorates, but object-generated harmful factors worsen
Solution Approach 1:
The housing components are designed to transition dynamically between closed and open configurations. When a user's finger becomes stuck, the device can be opened to release the finger, eliminating the harmful effect of potential finger damage while maintaining ease of operation.
Solution Approach 2:
The opening mechanism acts as an intermediary that facilitates safe removal of the device from the user's finger. This intermediary mechanism prevents direct harmful interaction between the stuck device and the user's finger, resolving the contradiction between ease of operation and harm prevention.
3Reliability
If a locking mechanism is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is integrated into the segmented housing structure, where the locking and opening functions are combined with the existing housing components. This segmentation approach maintains reliability for accurate sizing while avoiding excessive complexity by reusing structural elements.
Solution Approach 2:
The housing components serve multiple functions: they provide structural support, enable the opening mechanism, and incorporate the locking feature. This multi-functionality reduces overall device complexity while maintaining the reliability needed for accurate sizing operations.

AI summary
Methods, systems, and devices for ring sizing devices are described. A first ring sizing device may include a ring-shaped housing defined by a fixed ring size and including a first housing component and a second housing component connected at a first connection point via a hinge assembly and at a second connection point via a locking assembly. The hinge assembly may enable the second housing component to move relative to the first housing component to transition the ring-shaped housing between a closed configuration and an open configuration based on exertion of a force. A second ring sizing device may include a body and a gate movably coupled to the body via a hinge assembly. The body and the gate may form a first opening corresponding to a fixed ring size when they are aligned and may form a second opening, larger than the first opening, when they are mis-aligned.
