Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional photographing systems struggle to capture moments of moving objects, such as a tennis racket hitting a ball, requiring skilled photographers or multiple sequential images, and face challenges in remotely controlling the apparatus, especially when the object is in motion or hard to access.
Innovation Solution
A photographing system that includes a light emitting apparatus emitting visible light with command information and a photographing apparatus that receives this information to instruct various photographing functions, allowing for automatic control of capturing moving images based on the object's status and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a camera is fixed with a tripod and remotely controlled with an infrared remote controller, then the release time lag is restrained, but it becomes difficult to remotely control the photographing apparatus under certain conditions where the object lies
Solution Approach 1:
The light emitting apparatus is designed to perform multiple functions: it not only emits visible light for illumination but also transmits command information to control the photographing apparatus. This multi-functionality allows the system to overcome the limitations of traditional infrared remote controllers by using visible light communication that works under various conditions including when the object is in motion or in hard-to-access locations
Solution Approach 2:
The light emitting apparatus acts as an intermediary between the operator and the photographing apparatus. It receives commands from the operator and transmits them to the photographing apparatus through visible light communication, enabling remote control without requiring line-of-sight or specific positioning conditions that limit traditional infrared controllers
2Reliability
If multiple sequential images are photographed to capture a moving moment, then the desired moment can be captured, but the productivity and efficiency are reduced
Solution Approach 1:
The system uses feedback from the light emitting apparatus that detects the status and movement of the object. Based on this feedback, the photographing apparatus automatically determines the optimal timing to capture the moment, eliminating the need for multiple sequential shots and allowing efficient capture of moving moments with high reliability
Solution Approach 2:
The photographing system performs self-service by automatically detecting object status through the light emitting apparatus and autonomously deciding when to trigger the photographing function. This eliminates the need for manual operation or multiple attempts, thereby improving both the accuracy of capturing moving moments and the overall productivity
3Reliability
If conventional photographing systems are used for moving objects, then skilled photographers or multiple sequential images are required, but the ease of operation and accessibility are reduced
Solution Approach 1:
The system enables self-service operation where the light emitting apparatus automatically detects object status and movement, and the photographing apparatus autonomously captures images at the optimal moment. This eliminates the need for skilled photographers to manually time the shot, making the system easy to operate while maintaining high reliability in capturing moving moments
Solution Approach 2:
The feedback mechanism from the light emitting apparatus provides real-time information about object status and movement to the photographing apparatus. This automated feedback loop replaces the need for human skill and judgment in timing the photograph, thereby improving ease of operation while ensuring reliable capture of moving moments
