Solution Overview
Problem
In blade devices, increasing the bandwidth of signals transmitted via wirings on a backboard leads to noise resistance decline and error occurrence due to waveform distortion, limiting data transmission capacity, and securing a larger wiring area is challenging.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wired communication via backboard wirings is used to transmit control and monitoring information between blades, then data transmission capacity increases, but noise resistance declines and waveform distortion occurs leading to errors
Solution Approach 1:
The patent replaces the mechanical wired communication system (physical wirings on backboard) with an optical wireless communication system. The control blade and controlled blades use optical signals transmitted through air space instead of electrical signals through copper wirings, thereby eliminating waveform distortion and noise interference while maintaining high data transmission capacity.
Solution Approach 2:
The patent introduces air space as an intermediary medium for signal transmission between blades. Instead of direct electrical contact through wirings, optical signals propagate through the air space between the control blade and controlled blades, providing a clean transmission path free from electrical interference and waveform distortion.
2Productivity
If the bandwidth of signal transmitted via wirings on backboard is increased to accommodate more data, then data transmission capacity improves, but the wiring area required becomes larger which is difficult to secure
Solution Approach 1:
The patent eliminates the need for extensive physical wirings by substituting wired communication with optical wireless communication. The control blade transmits control information and monitoring information to controlled blades through optical signals in air space, removing the constraint of wiring area on the backboard while maintaining high bandwidth and data transmission capacity.
3Productivity
If more wirings are added to the backboard to increase data transmission capacity, then productivity improves, but device complexity increases
Solution Approach 1:
The patent extracts the communication function from the physical wiring infrastructure. By removing the dependency on multiple physical wirings and replacing them with optical wireless communication, the system achieves high data transmission capacity without increasing the number of physical connections, thereby reducing device complexity while improving productivity.
