Ring Wearable Terminal Adhesive Bonding Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ring-type wearable terminals with IC chips lack sufficient strength, leading to potential detachment of components and damage when interacting with readers.
Innovation Solution
The use of an adhesive agent to fill a recessed portion between two rings, securely fixing and protecting the communication unit, thereby enhancing the bonding strength and durability of the terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ring type wearable terminal is designed with a communication unit housed between two rings, then the terminal can perform wireless communication functions, but the bonding strength between rings is insufficient causing components to detach or IC chip to break during reader interactions
Solution Approach 1:
The invention transitions from surface-level bonding to volumetric bonding by filling the recessed portion with adhesive agent. This three-dimensional adhesive distribution throughout the recessed volume creates superior bonding strength compared to traditional surface bonding methods, directly resolving the contradiction between reliability and structural strength.
Solution Approach 2:
The invention employs a composite structure combining two rings with different materials properties, bonded through an adhesive agent that fills the recessed portion. This composite approach allows each component to contribute its optimal properties while the adhesive provides enhanced bonding, simultaneously improving both reliability and structural strength.
2Shape
If the communication unit is housed in a recessed portion between two rings, then the terminal achieves compact design, but the communication unit lacks sufficient protection during contact with readers
Solution Approach 1:
The adhesive agent filling the recessed portion serves as a pre-positioned cushioning medium that protects the communication unit before impact occurs. This beforehand cushioning absorbs and distributes impact forces from reader interactions, preventing damage to the housed communication unit while maintaining the compact recessed design.
3Strength
If adhesive agent is applied to bond two rings, then bonding strength is improved, but excess adhesive creates surface irregularities requiring additional polishing steps
Solution Approach 1:
The adhesive agent is applied with localized precision to fill only the recessed portion, creating a controlled distribution pattern. This local quality approach ensures adequate adhesive volume for strong bonding while confining the adhesive to specific areas, thereby reducing surface irregularities and minimizing the need for extensive polishing operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The improved bonding strength and protection of the communication unit within the ring-type wearable terminal ensure reliable functionality and durability, allowing for effective data transmission and resistance to impact from reader interactions.
Implementation Method 1
The first ring and the second ring are bonded by an adhesive agent that fills the recessed portion
Implementation Method 2
the communication unit is tightly fixed to the recessed portion and protected by the adhesive agent

AI summary
A ring type wearable terminal (10) includes: a first ring (12) that has a recessed portion (16) formed on a side surface thereof; a second ring (14) that is bonded to the first ring (12) and that covers the recessed portion (16); and a communication unit (26) that is housed in the recessed portion (16). The recessed portion (16) is filled with an adhesive agent (24). The adhesive agent (24) filling the recessed portion (16) bonds the first ring (12) and the second ring (14) and also fixes the communication unit (26) to the recessed portion (16) so as to protect the communication unit (26). This allows the strength of the ring type wearable terminal (10) to be improved.
