VSEngineering Contradiction Analysis

1Productivity

If the number of channels and bandwidths accessible concurrently is increased to meet bandwidth demands, then data throughput capability is improved, but internal interference increases which degrades wireless communications performance

Engineering Contradiction:

Solution Approach 1:

The system performs preliminary actions by measuring interference levels before wireless communications occur and by proactively adjusting clock frequencies of platform devices to prevent interference before it degrades performance. The platform controller proactively identifies potential interference sources and modifies their operating frequencies in advance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts clock frequencies of platform devices based on real-time interference measurements and wireless communication activity. The platform controller continuously monitors interference levels and dynamically modifies the operating parameters of platform devices to optimize the balance between performance and interference prevention.

Inventive Principle:
Principle #15Dynamics

2Use of energy by stationary object

If Dynamic Voltage Frequency Scaling (DVFS) is used to manage interference, then power consumption is reduced, but performance optimization is insufficient and interference management effectiveness is limited

Engineering Contradiction:

Solution Approach 1:

The system implements feedback mechanisms where the platform controller continuously monitors interference levels measured by the wireless communications device and uses this information to adjust the clock frequencies of platform devices. This closed-loop feedback ensures that interference management is effective and adaptive to changing conditions.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system changes operating parameters by adjusting clock frequencies of platform devices to frequencies that do not cause interference with wireless communications. The platform controller modifies these parameters dynamically based on measured interference levels and communication activity, optimizing both power consumption and interference prevention.

Inventive Principle:

Solution Approach 1:

The system dynamically adjusts clock frequencies based on real-time conditions. When wireless communications are active and interference is detected, the platform controller reduces clock frequencies of affected platform devices. When communications are inactive or interference is low, the system can operate at higher frequencies to maximize processing speed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary interference measurements and proactive frequency adjustments before platform devices generate harmful electromagnetic interference. The wireless communications device measures interference levels in advance, and the platform controller preemptively adjusts clock frequencies to prevent interference before it occurs.

Inventive Principle:
Principle #10Preliminary action
