Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wireline technologies are used to provide broadband connectivity, then reliable connectivity is achieved, but deployment costs and complexity increase significantly

Engineering Contradiction:
Improveconnectivity reliabilityVSAvoiddeployment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces wireline (mechanical/cable-based) communication systems with wireless communication systems. The gateway apparatus and wireless network access devices establish connectivity through wireless signals in a second protocol, eliminating the need for physical cable infrastructure while maintaining broadband connectivity functionality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The gateway apparatus is designed to support multiple communication protocols simultaneously - it handles both wireline communications (first protocol) and wireless communications (second protocol). This multi-functionality allows the system to transition from wired to wireless connectivity without requiring separate dedicated infrastructure for each protocol type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If wireless solutions like Wi-Fi and femtocell are deployed, then deployment flexibility improves, but connectivity reliability deteriorates due to dependency on wiring

Engineering Contradiction:
Improvedeployment flexibilityVSAvoidconnectivity reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent eliminates the mechanical/wireline dependency in wireless solutions by using pure wireless communication for both backhaul and access networks. The gateway apparatus communicates with wireless network access devices through wireless signals, removing the requirement for premises wiring while maintaining deployment flexibility.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If multiple carrier frequencies are used, then system capacity and coverage improve, but signal detection and measurement complexity increases

Engineering Contradiction:
Improvesystem capacityVSAvoidsignal measurement complexity
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The gateway apparatus measures signal quality metrics (such as RSRP, RSRQ, SINR) for signals on different carrier frequencies and uses this feedback information to make intelligent carrier frequency selection decisions. The system propagates quality measurements toward the wireless network access device and uses these measurements to determine optimal carrier assignments, creating a closed-loop feedback mechanism that simplifies the complexity of managing multiple frequencies.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically changes operating parameters (carrier frequency selection) based on measured signal conditions. The gateway apparatus detects wireless signals on multiple carrier frequencies, evaluates their quality, and selects the optimal carrier for communication, allowing the system to adapt to varying channel conditions and maximize capacity while managing measurement complexity through selective monitoring.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present disclosure generally discloses a hybrid wireless communication system configured to support wireless broadband connectivity for a geographic region including a set of wireless network access devices configured to support wireless communications by a set of communication gateways disposed at locations within the geographic region. The hybrid wireless communication system may be configured to operate across a set of multiple radio spectrum bands associated with a set of multiple carrier frequencies, respectively. The hybrid wireless communication system may be configured to jointly determine assignment of the locations (and, thus, the associated communication gateways) to the multiple carrier frequencies of the multiple radio spectrum bands and to configure the wireless network access devices to support the jointly determined assignment of the locations to the multiple carrier frequencies of the multiple radio spectrum bands.
