Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple apparatuses for wireless relaying are installed in an arbitrary area, then near field communication services can be provided to more users, but signal interference occurs between the apparatuses

Engineering Contradiction:
Improveservice coverageVSAvoidsignal interference
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by dynamically adjusting the output power level of wireless relaying apparatuses. The system monitors signal strength and coverage area, then modifies transmission parameters (power levels) to optimize service coverage while preventing signal interference between multiple apparatuses operating in the same area.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If apparatuses for wireless relaying are installed at specific locations considering coverage area, then signal interference is reduced, but coverage area inconsistency causes service availability issues

Engineering Contradiction:
Improvesignal interferenceVSAvoidservice availability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where the wireless relaying apparatus continuously monitors its own output signal levels and coverage characteristics. Based on this feedback, the system automatically adjusts transmission parameters to maintain consistent coverage area and ensure service availability, resolving the reliability issues caused by coverage inconsistency.

Inventive Principle:
Principle #23Feedback

3Area of stationary object

If coverage area of wireless relaying apparatus is increased, then more users can be served, but excessive overlap between coverage areas causes interference

Engineering Contradiction:
Improvecoverage areaVSAvoidsignal interference
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent applies dynamics by making the coverage area adjustable rather than fixed. The system dynamically modifies transmission power levels based on real-time conditions, allowing the coverage area to expand or contract as needed. This dynamic adjustment enables the network to serve more users while automatically preventing excessive overlap that would cause interference.

Inventive Principle:
Principle #15Dynamics

AI summary

An apparatus for wireless relaying comprises: a transmission unit for generating a wireless signal; an amplification unit for amplifying and outputting the wireless signal; a conversion unit for converting the wireless signal into a digital signal; and an adjustment unit for adjusting the amplification ratio of the amplifying unit so that the difference between an output level value of the digital signal and a predetermined target power is lower than a predetermined numerical value.
