1Volume of moving object
If multiple circuit boards are used to implement electronic device functions, then the electronic device can meet design requirements for size and height limitations, but the risk of connector connection errors increases, leading to potential device malfunction or component damage
Solution Approach 1:
The patent applies preliminary action by implementing connection detection before the device operates. The detection circuit checks connector connections in advance, identifying potential connection errors before they can cause device malfunction or component damage. This proactive detection mechanism ensures that connection issues are caught early, preventing the reliability problems that would otherwise arise from using multiple circuit boards.
2Reliability
If connector connection detection is implemented, then connection reliability is improved, but device complexity increases due to additional detection components
Solution Approach 1:
The patent merges the connection detection function with existing device components. The detection circuit is integrated into the device's existing circuitry, and the processor that already exists for device operation is also used to process detection signals and determine connection states. This consolidation approach improves connection reliability while minimizing the increase in device complexity by reusing existing components rather than adding entirely separate detection systems.
Solution Approach 2:
The patent applies universality by making existing components serve multiple functions. The processor not only controls device operation but also processes detection signals to determine connector connection states. The detection circuit is designed to work with the existing processor architecture, allowing one component to fulfill multiple roles and reducing overall system complexity while maintaining improved connection reliability.

AI summary
A connection detection device and a connection detection method for detecting a connection state between a first connector and a second connector are provided. The first connector includes detection pins. The second connector includes loop pins corresponding to the detection pins. The connection detection device includes a bias voltage generator, a detection circuit, and a processor. The bias voltage generator applies a reference bias voltage to the detection pins. The detection circuit detects bias values on the detection pins. When each bias value is shifted to a first bias value based on a connection loop formed between the detection pins and the loop pins, the detection circuit provides a first detection signal. When at least one of the bias values is not shifted to the first bias value, the detection circuit provides a second detection signal. The processor provides an alarm signal in response to the second detection signal.
