Solution Overview

Problem

Current wearable devices require both hands or additional support to wear or remove, causing inconvenience, especially for those unfamiliar with one-handed operations, and may fall and get damaged if not handled carefully.

Innovation Solution

A wearable device design featuring a main body with a tail and hook portion and a coupling member with a buckle hole that can be easily inserted or separated with one hand, utilizing a torsion spring and adjustable clamping member for secure fitting without needing to lean on other objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional wearable device fastening methods are used, then the device can be securely fixed, but both hands or additional support objects are required to wear or remove the device

Engineering Contradiction:

ImproveEase of wearing and removing deviceVSAvoidComplexity of fastening mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The fastening mechanism is divided into separate components: a hook portion integrated into the main body and a coupling member with a buckle hole. This segmentation allows the coupling member to be manipulated independently with one hand while the main body remains stable, eliminating the need for two hands or external support objects during wearing and removal operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The coupling member acts as an intermediary element between the user's hand and the main body. By providing a dedicated buckle hole that can be easily engaged with the hook portion, it mediates the fastening action, allowing secure attachment while maintaining ease of one-handed operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If conventional wearable device fastening methods are used, then the device can be fixed securely, but significant time is required to wear or remove the device

Engineering Contradiction:

ImproveSpeed of wearing and removing deviceVSAvoidTime required for wearing and removing device

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The hook portion is pre-formed and permanently attached to the main body, ready for immediate engagement. The coupling member is designed with a buckle hole that aligns with the hook portion, allowing users to quickly snap the components together without requiring complex manipulation or multiple steps, thereby reducing the time needed to wear or remove the device.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If conventional wearable device fastening methods are used, then the device can be fixed, but it may fall on the ground and become damaged if not handled carefully

Engineering Contradiction:

ImproveStability of device fixationVSAvoidRisk of device damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Instead of requiring the user to carefully position and attach the main body to their wrist, the design inverts the operation by providing a coupling member that can be easily attached to the main body. This reversal of the fastening sequence allows the main body to remain stable and controlled during the wearing process, reducing the risk of accidental drops and damage.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A wearable device includes a main body and a coupling member. The main body has a tail portion and a hook portion at two opposite sides respectively. One end of the coupling member is connected to the tail portion. A buckle hole of another end of the coupling member is for sleeving onto the hook portion to fix the main body to a subject.
