Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras are used in smart wearable devices to provide video-related functions, then the functionality and application scope are improved, but the synchronization accuracy between cameras deteriorates
Solution Approach 1:
The patent introduces a central processor as an intermediary that receives trigger signals and generates synchronized hardware trigger signals for multiple cameras. This central coordinator acts as a mediator that resolves the synchronization conflict between independently operating cameras, ensuring they capture images at precisely the same moment while maintaining individual functionality.
Solution Approach 2:
The patent merges the trigger signal generation function into a single central processor that controls all cameras. By combining the timing control of multiple cameras under one unified timing mechanism, the system achieves precise synchronization across all camera modules while maintaining their separate operational capabilities.
2Measurement precision
If hardware trigger signals are used to synchronize camera capture, then the capture timing precision is improved, but the clock difference between independently clocked portions causes synchronization deterioration
Solution Approach 1:
The patent implements a feedback mechanism where the central processor receives trigger signals, determines the appropriate timing based on clock synchronization status, and generates corresponding hardware trigger signals for each camera. This feedback loop ensures that even with independent clocks, the system can compensate for timing differences and maintain reliable synchronization.
Solution Approach 2:
The patent performs preliminary clock synchronization and timing determination before initiating camera capture. The central processor pre-calculates the timing offsets and prepares synchronized trigger signals in advance, ensuring that when capture is initiated, all cameras are already positioned to capture at the correct moment despite having independent clocks.

AI summary
A wireless smart wearable device includes a first portion and a second portion that can communicate with each other wirelessly. The first portion and the second portion respectively includes a first processor and a second processor, a first wireless communication module and a second wireless communication module, a first camera and a second camera, a first image acquisition module and a second image acquisition module, and a first clock and a second clock. The first image acquisition module transmits a first hardware trigger signal based on the first clock to the first camera, and the second image acquisition module transmits a second hardware trigger signal based on the second clock to the second camera. At least one processor enables the first wireless communication module and the second wireless communication module to continuously perform wireless communication with each other and/or wireless communication between both of them and a smart device, and determines a clock difference to achieve synchronization between the first and second hardware trigger signals.
