Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The backplane in communications devices often becomes a bottleneck during capacity expansion and upgrade, limiting the performance and life cycle of the device due to its difficulty in meeting future performance requirements.
Innovation Solution
A method and apparatus for adjusting the transmission rate by adding additional data in a specific proportion to the first data, allowing for a higher second rate, which is not an integer multiple of the first rate, to overcome the limitations of the backplane and support future performance needs.

Engineering Contradiction Analysis
1Productivity
If the backplane hardware is upgraded to meet future performance requirements, then the device capacity and performance can be expanded, but the cost increases and the upgrade process becomes complex
Solution Approach 1:
The patent changes the transmission rate parameter of the backplane from a fixed hardware-determined value to an adjustable software-controlled value. By dynamically adjusting the transmission rate parameter, the system can achieve capacity expansion without physical hardware upgrades, thereby avoiding the complexity and cost of backplane replacement while improving device capacity.
2Speed
If the transmission rate is increased to meet future performance requirements, then the device can support higher speeds, but frequency holes and signal degradation occur
Solution Approach 1:
The patent implements dynamic transmission rate adjustment, allowing the system to adaptively select optimal transmission rates based on current signal conditions and requirements. This dynamic approach enables the system to avoid fixed rate limitations and frequency holes while maintaining signal quality through flexible rate selection and adjustment.
3Speed
If additional data is added to increase the transmission rate, then the second rate becomes greater than the first rate, but the data structure becomes more complex
Solution Approach 1:
The patent segments the data transmission process into distinct components: original data, additional data, and combined second data. By dividing the data structure into manageable segments with clear demarcation, the system can implement variable rate transmission while maintaining organizational clarity and reducing overall structural complexity.
