Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a wireless remote control system uses a fixed number of transmission channels, then the system structure remains simple, but the number of controllable devices is limited to the number of channels
Solution Approach 1:
The patent divides the control system into multiple stages, with each stage containing multiple crosspoint switches that can be independently controlled. This segmentation allows the system to expand the number of controllable devices beyond the original channel limit by creating a multi-level control architecture where each stage handles a portion of the total device control task.
Solution Approach 2:
The patent introduces a temporal dimension to the control system by implementing sequential switching across multiple stages. Instead of requiring all channels to be available simultaneously, the system uses time-division multiplexing where different groups of devices are controlled in different time slots through different stages, effectively expanding control capacity without proportionally increasing simultaneous channel requirements.
2Quantity of substance
If the number of transmission channels is increased to control more devices, then more devices can be controlled, but the complexity of the remote control system increases
Solution Approach 1:
The patent implements a nested architecture where multiple stages of crosspoint switches are arranged in a hierarchical structure. Each stage contains crosspoint switches that are nested within the overall multi-stage system, with each stage handling a subset of the total control task. This nesting allows systematic expansion of output channels while maintaining manageable complexity at each individual stage level.
Solution Approach 2:
The patent employs dynamic switching mechanisms where crosspoint switches can be sequentially activated and deactivated based on control signals. This dynamic operation allows the system to effectively multiply the number of usable output channels over time, as each crosspoint switch can serve multiple logical channels through time-division multiplexing rather than requiring permanent dedicated physical channels for each device.
3Quantity of substance
If cascaded stages of crosspoint switches are used to multiply output channels, then the number of controllable devices increases, but the device complexity and control mechanism complexity increase
Solution Approach 1:
The patent designs each crosspoint switch to perform multiple functions: it serves as a channel selector, a signal router, and a control element for multiple downstream devices. This multi-functionality reduces the need for separate dedicated control mechanisms for each channel, as each crosspoint switch handles multiple control tasks, thereby mitigating the increase in overall control mechanism complexity despite the expansion of output channels.
Solution Approach 2:
The patent introduces intermediate control stages with crosspoint switches that act as mediators between the single remote controller and the large number of controlled devices. These intermediate stages break down the complex one-to-many control problem into simpler one-to-few control tasks at each stage, making the overall control mechanism more manageable despite the large total number of controlled devices.

AI summary
A remote wireless system is presented to increase the output channels through implementation of cascaded multiplier stages. The output channels are used to control a larger number of devices and appliances by switching on and off through a wireless remote controller. The system comprises a transmitter, a receiver, a first multiplier stage, a second multiplier stage, one or more multiplier stages each cascaded to the prior multiplier stage, and a power supply.
