Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional structural design with internal framework and external housing is used, then functional components can be assembled into unified structure, but device size and weight increase
Solution Approach 1:
The patent merges the internal framework and external housing into a unified integrated housing structure. The housing serves dual purposes as both structural support and external enclosure, eliminating separate framework components and reducing overall device weight while maintaining assembly capability for functional components.
Solution Approach 2:
The housing structure is designed to perform multiple functions simultaneously: providing structural support, serving as external enclosure, and facilitating component assembly. This multi-functional design eliminates the need for dedicated framework components, reducing weight while maintaining manufacturing ease.
2Ease of manufacture
If traditional structural design with internal framework and external housing is used, then functional components can be assembled into unified structure, but device volume increases
Solution Approach 1:
The patent merges the internal framework and external housing into a unified integrated housing structure. The housing serves dual purposes as both structural support and external enclosure, eliminating separate framework components and reducing overall device volume while maintaining assembly capability for functional components.
3Device complexity
If battery bracket is fixed within accommodating cavity, then device structure is simplified, but battery replacement becomes difficult
Solution Approach 1:
The battery bracket is designed with rotatable connection to the housing, allowing it to rotate between a working position (where it closes the battery window) and a maintenance position (where it can be easily removed). This dynamic design maintains structural integrity during operation while enabling easy battery replacement for maintenance.
4Ease of repair
If battery bracket rotates freely, then battery replacement is easy, but device structure becomes complex
Solution Approach 1:
The battery bracket rotates about a pivot structure formed between the battery bracket and housing inner wall, enabling easy battery replacement while maintaining a relatively simple device structure through integrated pivot design.

AI summary
A wearable device includes a housing assembly and a battery assembly, the housing assembly including an accommodating cavity and a battery window, the battery assembly including a battery bracket configured to mount a battery. A second pivot structure and a locking structure are formed between the battery bracket and an inner wall of the housing assembly. The battery bracket can rotate about the second pivot structure relative to the housing assembly to allow the battery bracket to enter and exit the accommodating cavity through the battery window. The locking structure can lock the battery bracket within the accommodating cavity in a state in which the battery bracket closes the battery window. By establishing a structural connection relationship between the battery bracket and the inner wall of the housing assembly by means of the second pivot structure and the locking structure, and by using the housing assembly as a structural mounting carrier for the battery assembly, a count of related connecting parts may be effectively reduced and the full utilization of the structure and space of the housing assembly may be realized, which is conducive to the miniaturization and lightweight design of the device. At the same time, by adjusting the battery bracket, it is convenient to replace the battery and maintain the integrity of the overall external structure of the device.
