Strap Adapter Button Mechanism for Wearable Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cumbersome process of replacing straps on wearable electronic devices limits their use as fashion items, as existing fastening structures are inefficient for easy attachment and detachment.
Innovation Solution
A strap adapter with a housing, a first fastening part protruding from the housing to connect with the device's main body, and a button to facilitate easy engagement and disengagement, allowing for quick strap replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional fastening structure is used to attach the strap to the main body, then the connection is secure and reliable, but the attachment and detachment process becomes cumbersome and time-consuming
Solution Approach 1:
The fastening part is designed to transition between a locked state (engaged with the main body) and an unlocked state (separated from the main body). The button mechanism dynamically changes the position of the fastening part, enabling quick transition between attached and detached states, thus resolving the contradiction between secure connection and easy detachment.
Solution Approach 2:
The strap assembly is segmented into three main components: the strap itself, the housing that contains the button and fastening mechanism, and the fastening part that interfaces with the main body. This segmentation allows the fastening part to be independently manipulated via the button, enabling quick attachment and detachment without moving the entire strap assembly.
2Productivity
If a simple fastening mechanism is used, then the attachment process is quick and easy, but the connection reliability and security are compromised
Solution Approach 1:
The fastening part dynamically transitions between locked and unlocked positions. When locked, it provides secure connection; when unlocked (via button press), it allows quick detachment. This dynamic state change enables both high productivity during replacement and high reliability during wear.
Solution Approach 2:
The button acts as an intermediary mechanism that controls the state of the fastening part. By pressing the button, the user activates the release mechanism, which then moves the fastening part to the unlocked state. This intermediary control mechanism ensures reliable operation while maintaining quick replacement speed.
3Ease of operation
If the button is fully exposed outside the housing, then it is easy to access and operate, but the aesthetic design and compact structure are compromised
Solution Approach 1:
The button is nested within the housing structure, with only a portion of the button exposed for operation. The button's shaft extends through the housing, allowing the button head to be accessible from the outside while the base remains integrated into the housing. This nesting approach maintains both aesthetic design and operational accessibility.
Solution Approach 2:
Different portions of the button have different levels of exposure and function. The button head is exposed for operation, the shaft provides mechanical linkage, and the base is integrated into the housing for structural support. This local differentiation of quality allows the button to satisfy both aesthetic and operational requirements simultaneously.

AI summary
An electronic device may include a main body including a front plate, a rear plate disposed to be spaced apart from the front plate, a lateral member surrounding a space between the front plate and the rear plate, and a display viewed through at least a portion of the front plate. The electronic device may further include a housing having a space therein and combined with a strap at one side thereof in a first axial direction, a first fastening part protruding from another side of the housing toward the main body and detachably connected to the main body, a second fastening part formed in the main body and engaged with the first fastening part, and a button disposed in the housing, exposed at least in part to an outside of the housing, and moving the first fastening part to be separated from the second fastening part.
