Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal transmission systems in mobile homes, caravans, and boats lack efficient wireless communication solutions for real-time monitoring and control of electrical and electronic components, often requiring physical connections and incurring costs when using cellular networks, and may not function in areas with poor coverage.
Innovation Solution
A signal transmission device with a transmitting and receiving unit that establishes a local wireless data connection, such as Bluetooth or WLAN, to transmit data from components to mobile terminals without a display, allowing integration into existing data buses and enabling bidirectional communication for control and regulation, thus providing real-time status updates and control functions wirelessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display device with screen is used to show component status information, then information display capability is improved, but device complexity and installation space requirements increase
Solution Approach 1:
The patent extracts the display function from the signal transmission device by using a mobile terminal's display instead. The transmitting and receiving unit only handles data transmission and reception, while the mobile terminal displays the component status information. This separation reduces the complexity of the signal transmission device while maintaining full information display capability.
Solution Approach 2:
The mobile terminal acts as an intermediary between the signal transmission device and the user. It receives data from the transmitting and receiving unit via wireless connection and presents the information through its display interface, thereby eliminating the need for a built-in display in the signal transmission device.
2Reliability
If wireless data transmission is implemented without cellular network, then cost and reliability are improved, but communication range and infrastructure requirements are limited
Solution Approach 1:
The patent replaces the cellular network infrastructure (external mechanical/system dependency) with a local wireless data connection system. By using Bluetooth or WLAN technology, the system achieves reliable communication without depending on external cellular towers, thereby improving reliability while maintaining adaptability through local networking capabilities.
3Stability of the object's composition
If physical cable connections are used for data transmission, then connection stability is improved, but ease of operation and installation flexibility are reduced
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless data transmission system using Bluetooth or WLAN. This eliminates the need for physical cable connections while maintaining stable communication through established wireless protocols, thereby improving installation flexibility and ease of operation without sacrificing connection stability.
4Adaptability or versatility
If multiple electrical and electronic components are networked together, then system functionality is improved, but device complexity and wiring requirements increase
Solution Approach 1:
The patent implements a universal data bus system (CI bus) that can connect multiple different electrical and electronic components through a common communication protocol. This allows various components (refrigerators, heaters, lighting, etc.) to be networked together without requiring separate wiring for each connection, thereby improving system functionality while reducing overall wiring complexity.
Solution Approach 2:
The patent replaces extensive physical wiring requirements with wireless data transmission for accessing component status information. While the CI bus provides structured connectivity for system functionality, the wireless transmission layer eliminates the need for additional cables between the data bus and the user interface, reducing overall wiring complexity.
