Remote Control Module Power Management for Digital Camera
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital cameras face challenges in providing a low-profile, reduced wind resistance design for capturing images while mounted on moving objects, and their remote control systems consume excessive power due to continuous notification requirements.
Innovation Solution
A digital camera system with two image capture systems and a remote control module that enters a low-power state after inactivity, conserving battery life by only activating when user controls are engaged, and featuring a streamlined design for reduced wind resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the remote control continuously monitors camera state changes, then remote control functionality is maintained, but power consumption increases rapidly
Solution Approach 1:
The remote control device transitions between active and sleep states periodically. During active state, it receives and processes camera state notifications. During sleep state, it conserves power by disabling the notification receiver, waking up only when needed to send commands or receive updated notifications.
Solution Approach 2:
The remote control device dynamically adjusts its operational state based on activity. It switches from a low-power sleep mode to an active mode when user input is detected or when it needs to communicate with the camera, and returns to sleep mode after a timeout period of inactivity.
2Adaptability or versatility
If the camera is mounted on moving objects, then capture capability is improved, but wind resistance and profile susceptibility increase
Solution Approach 1:
The camera device includes a rotatable housing that allows rotation between portrait and landscape orientations. This dimensional change enables the camera to be mounted in different orientations on moving objects, optimizing the profile presentation to reduce wind resistance while maintaining capture capability.

AI summary
A digital camera system includes an image capture module and a remote control module. The image capture module includes an image capture system and a first wireless communication system. The remote control module includes a status display with one or more status display elements for displaying status information pertaining to the image capture module, a battery-operated power supply, one or more user controls, a second wireless communication, and a power management system providing a normal-power state and a low-power state. The system is configured such that when a user activates one of the user controls while the remote control module is in the low-power state the remote control module is set to operate in the normal-power state, a status inquiry is sent to the image capture module, and returned status information is displayed on the status display.
