Universal Remote Control for Digital Video Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of digital video cameras from different manufacturers often need to purchase multiple remote control apparatuses, as existing solutions are not compatible with both LANC (communication control) and direct control types, leading to a lack of a universal remote control solution.
Innovation Solution
A remote control apparatus featuring a microcomputer circuit that converts operation signals into communication signals and a switch to toggle between direct and communication signal transmission, allowing compatibility with both control types using a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a remote control apparatus is designed for direct control type, then it can directly transmit operation signals to the digital video camera, but it cannot control communication control type cameras
Solution Approach 1:
The remote control apparatus incorporates a switch that allows dynamic switching between direct transmission mode and communication signal mode. This enables the device to adapt its signal transmission method based on the type of digital video camera being controlled, resolving the contradiction between versatility and complexity by making the transmission mechanism changeable rather than fixed
Solution Approach 2:
The remote control apparatus is designed to perform multiple functions by supporting both direct control type and communication control type cameras through a single device. The inclusion of a microcomputer circuit for signal conversion and a switch for mode selection enables one remote control to serve multiple control types, achieving universality
2Adaptability or versatility
If a remote control apparatus is designed for communication control type, then it can transmit control signals through a microcomputer circuit, but it cannot directly control direct control type cameras
Solution Approach 1:
The apparatus uses a switch to dynamically select between communication signal transmission and direct signal transmission. This dynamic configuration allows the same device to function differently depending on the camera type, achieving versatility without requiring separate devices for each control type
Solution Approach 2:
The microcomputer circuit acts as an intermediary that converts operation signals into communication signals when needed. This intermediary component enables compatibility with communication control type cameras while the switch allows bypassing this intermediary for direct control type cameras, resolving the contradiction
3Reliability
If users buy separate remote control apparatuses for different control types, then each camera type can be controlled optimally, but the quantity of remote control apparatuses increases
Solution Approach 1:
The remote control apparatus is designed as a universal device that can control both direct control type and communication control type cameras. By integrating both direct transmission and communication signal transmission capabilities in a single device, the need for multiple separate remote controls is eliminated, reducing the quantity of apparatuses while maintaining reliable control functionality for each camera type

AI summary
A remote control apparatus that is compatible with two types of digital video cameras. The remote control apparatus includes a start and stop switch which operates start and stop, a zoom volume control which operates a zoom, a microcomputer circuit which converts operation signals of the start and stop switch and the zoom volume control into communication signals, and a switch which changes whether the operation signals of the start and stop switch and the zoom volume control are transmitted to the digital video camera without passing through the microcomputer circuit or the communication signal obtained by inputting the operation signal to the microcomputer circuit is transmitted to the digital video camera.
