Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatuses with free slots for connecting electronic circuit boards suffer from inconsistent signal transmission quality due to indefinite signal transmission distances, leading to potential errors and limited slot usage.

Engineering Contradiction Analysis
1Adaptability or versatility
If electronic circuit boards are connected to free slots with indefinite positions, then slot flexibility and adaptability are improved, but signal transmission quality becomes inconsistent due to varying transmission distances
Solution Approach 1:
The patent implements dynamic adjustment of transmission parameters (drive current level, signal amplitude, frequency) based on the actual position of circuit boards in slots. The system transitions from fixed parameters to dynamic parameters that adapt to varying transmission distances, allowing any board to be placed in any slot while maintaining consistent signal quality through real-time parameter optimization.
Solution Approach 2:
The patent changes physical parameters (drive current level, signal amplitude, frequency) based on transmission distance. By detecting the slot position and adjusting these parameters accordingly, the system compensates for signal degradation over distance, ensuring uniform transmission quality across all slots regardless of board position.
2Productivity
If transmission speed and processing speed are increased, then productivity is improved, but signal transmission distance capability is reduced due to fixed parameters
Solution Approach 1:
The system dynamically adjusts transmission parameters based on actual transmission distance rather than using fixed parameters. This allows the system to maintain high processing speeds while adapting the signal characteristics to match the actual physical distance, thereby extending the effective transmission distance capability at high speeds.
Solution Approach 2:
The patent employs feedback mechanisms where the system detects transmission quality and slot position, then adjusts parameters accordingly. This feedback loop enables the system to optimize transmission distance at high speeds by continuously monitoring and adapting signal parameters based on actual performance and physical conditions.

AI summary
According to one embodiment, a monitor/control unit of an electronic circuit board monitors the receiving state of a transmitting/receiving circuit unit and controls a parameter setting unit, causing the same to change the reception parameter of the transmitting/receiving circuit unit, and if the receiving state remains not changed to a specified state, the monitor/control unit informs a host control device of this fact. The host control device instructs the switching process board to designate a channel, thereby to change, the specified state, the receiving sate of the electronic circuit board associated with the channel informed of that fact.
