Wearable Device Detachable Hinge Mechanism for Strap Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable electronic devices, such as smart watches or smart wristbands, are uncomfortable and inconvenient for long-term use due to their undetachable flexible portions.
Innovation Solution
A wearable electronic device design featuring a main body, flexible members, and detachable connecting members with hinges, allowing the device to be pivotally connected and worn either on the wrist or neck, with interchangeable connecting and flexible members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flexible portion is made undetachable, then the device structure is simplified and more reliable, but the comfort and convenience for long-term usage deteriorates
Solution Approach 1:
The wearable device is divided into a main body and a detachable flexible portion connected through connecting members. This segmentation allows the flexible portion to be detached and replaced, resolving the contradiction by enabling both structural reliability (through secure connection mechanisms) and usage comfort (through detachable design that prevents long-term wear issues).
Solution Approach 2:
The connection between the main body and flexible portion is made dynamic rather than static. The detachable connecting members with hinge mechanisms allow the connection state to change between attached and detached, providing adaptability for different usage scenarios while maintaining reliability when connected and comfort through replaceability.
2Device complexity
If the flexible portion is made undetachable, then the device structure is simplified, but the adaptability for different wearing scenarios deteriorates
Solution Approach 1:
The detachable connecting members are designed with universal engagement features that can accommodate different flexible portion configurations. The hinge mechanism and connecting structure allow the same main body to be adapted for different wearing scenarios (wrist, neck, etc.) by simply changing the flexible portion, achieving multi-functionality without proportionally increasing complexity.
Solution Approach 2:
The connecting members serve as intermediary components between the main body and flexible portions. These intermediaries provide standardized interfaces that simplify the overall structure while enabling adaptability - the hinge and connection mechanism act as a mediator that allows easy attachment and detachment of different flexible portions for different wearing scenarios.
3Adaptability or versatility
If a detachable connecting mechanism is added, then the adaptability and comfort are improved, but the device complexity increases
Solution Approach 1:
The complexity of the detachable connecting mechanism is localized to specific connection points rather than being distributed throughout the entire device. The hinge and connecting members are concentrated at the interface between the main body and flexible portion, allowing the majority of the device structure to remain simple while achieving adaptability only where needed.
Solution Approach 2:
The connecting members incorporate flexible hinge mechanisms that provide the necessary adaptability through controlled flexibility. The hinge allows angular movement for comfortable wearing while maintaining a compact structure, achieving high adaptability with minimal complexity by using flexible mechanical elements rather than complex adjustment systems.

AI summary
A wearable electronic device is provided, including a main body, a flexible member, a connecting member, and a first hinge. The connecting member is connected to the flexible member and has a hook portion. The first hinge is disposed on the main body and detachably engaged with the hook portion, such that the connecting member is pivotally connected to the main body.
