Air Conditioner Control Substrate for Switchable Power Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing indoor air conditioner equipment requires increased workload when switching between power-receiving methods, as the relay terminal block needs to be exchanged between separate and external power-receiving methods.
Innovation Solution
A control substrate with integrated power-supply and communication circuits, along with first and second terminal blocks and switches, allows for seamless switching between power-receiving methods without exchanging terminal blocks, preventing miswiring and ensuring proper connection between circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a relay terminal block is exchanged when switching power-receiving methods, then the power supply configuration can be changed between separate and external power-receiving methods, but the workload increases due to the need to exchange terminal blocks
Solution Approach 1:
The relay terminal block is designed with multi-functionality to support both separate power-receiving method and external power-receiving method. The terminal block includes multiple terminal groups (first terminal group for power supply, second terminal group for communication) that can be configured for different power-receiving methods through switching elements, eliminating the need to exchange terminal blocks when changing power supply configurations.
Solution Approach 2:
The relay terminal block incorporates switching elements (such as switches or relays) that dynamically reconfigure the connection between terminals based on the selected power-receiving method. This dynamic reconfiguration allows the same terminal block to adapt between different power supply configurations without physical exchange, reducing installation workload.
2Reliability
If a relay terminal block is exchanged when switching power-receiving methods, then the appropriate terminal block can be used for each method, but the installation time increases due to the exchange process
Solution Approach 1:
The relay terminal block is pre-configured with multiple terminal groups and switching elements during manufacturing, preparing it in advance to support both separate and external power-receiving methods. This preliminary preparation eliminates the need for on-site terminal block exchange, reducing installation time while maintaining configuration reliability.
Solution Approach 2:
The terminal block's multi-functional design allows it to reliably support different power-receiving methods without requiring exchange. The switching elements enable the terminal block to maintain appropriate connections for either method, ensuring reliability while eliminating the time-consuming exchange process.
3Manufacturing precision
If terminal blocks are dedicated to specific power-receiving methods, then the connection configuration can be optimized for each method, but the device complexity increases due to having multiple terminal blocks
Solution Approach 1:
Multiple terminal blocks dedicated to different power-receiving methods are merged into a single relay terminal block with multi-functional capabilities. The combined terminal block includes first terminal groups for power supply connections and second terminal groups for communication connections, along with switching elements that enable it to perform the functions of multiple dedicated terminal blocks, thereby reducing device complexity while maintaining connection precision.
