Rotating Shaft Connecting Structure for Wearable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable electronic devices, such as eyeglasses, face issues with cable exposure leading to damage and water ingress due to external cable placement, which compromises connection tightness and waterproofness.
Innovation Solution
A connecting structure comprising a first and second component with rotating shafts and a transmission component, where the rotating shaft connects the components rotatably, ensuring the transmission component is not exposed and maintaining waterproofness by being housed within the components, and the rotating shaft's cavity and opening facilitate secure and protected passage of the transmission component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If transmission cables are placed outside the eyeglass frame and leg, then the structure is simple and easy to manufacture, but the cables are exposed and prone to damage and water ingress
Solution Approach 1:
The transmission component is nested within the rotating shaft, which is inserted into shaft holes of the first and second components. The rotating shaft has a cavity that houses the transmission component, protecting it from external damage and water ingress while maintaining a compact structure.
Solution Approach 2:
The rotating shaft acts as a protective shell that encloses the transmission component. The shaft has openings that allow the transmission component to pass through while providing protection, balancing accessibility with waterproofness.
2Device complexity
If transmission cables are placed outside the eyeglass frame and leg, then the structure is simple, but the cables are exposed leading to damage and water ingress
Solution Approach 1:
The transmission component is nested within the rotating shaft's cavity, providing protection while maintaining structural integrity. This nested arrangement ensures connection tightness by securing the transmission component inside the shaft rather than leaving it exposed.
Solution Approach 2:
The rotating shaft serves as an intermediary structure between the first and second components. It provides a protected passage for the transmission component, ensuring both connection tightness and protection from external factors.
3Reliability
If the rotating shaft connects the components rotatably with cavity and opening, then the transmission component is protected from water ingress, but the structure becomes more complex
Solution Approach 1:
The rotating shaft performs multiple functions: it connects the first and second components rotatably, provides a protective cavity for the transmission component, and maintains waterproofness through its enclosed structure. This multi-functionality reduces the need for additional separate protective components.
Solution Approach 2:
The protective cavity and rotational connection functions are merged into a single rotating shaft structure. The shaft's cavity and opening design combines protection and mobility requirements into one integrated component, reducing overall device complexity.
