Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional housing structure with internal frame is used, then structural stability is maintained, but device size and weight increase
Solution Approach 1:
The patent removes the traditional internal frame structure from the housing assembly. The interface assembly is directly connected to the housing assembly without requiring an internal frame for support, thereby eliminating unnecessary structural components and reducing overall device weight while maintaining structural stability.
Solution Approach 2:
The interface assembly is integrated directly with the housing assembly through direct connection. The fixing member connects the interface assembly to the housing assembly wall, merging what were previously separate structural elements (internal frame and housing) into a more compact configuration, reducing both weight and structural complexity.
2Volume of moving object
If components are tightly integrated, then device miniaturization is achieved, but maintenance and repair difficulty increases
Solution Approach 1:
The device is divided into distinct modular assemblies: housing assembly, interface assembly, and control board assembly. Each assembly can be independently accessed and maintained. The interface assembly can be disconnected from the housing assembly by separating the fixing member from the housing assembly wall, enabling easy maintenance without requiring complete disassembly of the entire device.
3Manufacturing precision
If fixed internal structure is used, then manufacturing precision is maintained, but assembly and disassembly time increases
Solution Approach 1:
The connection between the interface assembly and housing assembly is designed to be dynamically adjustable. The fixing member can be easily attached to and detached from the housing assembly wall through simple insertion and engagement movements along the radial direction, enabling rapid assembly and disassembly while maintaining precise positioning through the fixing structures.

AI summary
The present disclosure provides a wearable device comprising a housing assembly, an interface assembly, and a control board assembly. The housing assembly includes a connection port. The interface assembly includes a wiring end and an interface end opposite to each other, the interface assembly is disposed within the housing assembly in a manner that the interface end faces the connection port, and the interface assembly is connected to an inner wall of the housing assembly. The control board assembly is disposed within the housing assembly and is connected to the wiring end through a wire assembly. By arranging the interface end and the connection port to face and communicate with each other, an external device may be connected to the wearable device in a plug-in manner through the interface assembly, thereby supporting functions such as device debugging, system upgrades, and adjustment of operating modes and parameters. Meanwhile, by connecting the interface assembly to the housing assembly, the housing assembly may be directly used as an installation carrier for the interface assembly, which not only fully utilizes the structure and internal space of the housing assembly, but also facilitates miniaturization and weight reduction of the wearable device, and facilitates disassembly and maintenance of the wearable device.
