Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Ring type wearable terminals with size variability are challenging to manufacture without increasing costs, as existing designs require multiple annular antennas of different sizes.

Innovation Solution

A ring type wearable terminal featuring a ring-shaped flexible substrate with a bonding portion that can be adjusted at various positions along its longitudinal direction, allowing the same substrate to be used for different ring sizes, and comprising a communication unit housed within a recessed portion of the ring, bonded with an adhesive agent for enhanced strength and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple annular antennas of different sizes are used to accommodate various ring sizes, then the adaptability to different finger sizes is improved, but the manufacturing cost increases

Engineering Contradiction:

Improvesize adaptabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

A single flexible substrate design serves multiple ring sizes through adjustable bonding portions. The substrate can be configured for different circumferences by bonding at different positions, eliminating the need for multiple size-specific components and reducing manufacturing complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The flexible substrate incorporates adjustable bonding portions that can be positioned at different locations along the longitudinal direction. This dynamic configuration allows the same substrate to adapt to different ring sizes, providing size variability without requiring multiple fixed-size components

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the ring size is increased to fit larger fingers, then the size adaptability is improved, but the risk of the ring falling off decreases only if the size fits properly

Engineering Contradiction:

Improvesize rangeVSAvoidretention stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The adjustable bonding portions allow the ring to be dynamically configured to match different finger sizes and shapes. This ensures proper fit and retention stability across various user populations, preventing the ring from falling off while maintaining size adaptability

Inventive Principle:

Principle #15Dynamics

AI summary

A ring type wearable terminal is provided with a ring and a communication unit that is housed in the ring. The communication unit is provided with a ring-shaped flexible substrate. The flexible substrate is provided with a bonding portion formed such that the bonding portion can be bonded at a plurality of different positions in a longitudinal direction in accordance with the size of the ring. By changing a bonding position of the bonding portion, the diameter of the flexible substrate formed in a ring shape can match the size of the ring. Thereby, a single flexible substrate can be used for a ring of multiple sizes, and an increase in the manufacturing cost when offering a size range of multiple sizes can thus be prevented.
