Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mesh routers continue to operate in normal mode to maintain network availability, then network connectivity is preserved, but energy consumption increases unnecessarily when no users are present

Engineering Contradiction:
Improvenetwork connectivityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the operational state of mesh routers based on real-time occupancy detection. When the sensing module detects that no users are present in the detection zone, the controller automatically transitions routers from normal mode to energy-saving mode, and vice versa when users return, thereby optimizing energy consumption while maintaining network availability only when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements a feedback mechanism where the sensing module continuously monitors the detection zone for user presence and provides this information to the controller. The controller then adjusts router operational states based on this feedback, creating a closed-loop control system that adapts network power consumption to actual usage conditions.

Inventive Principle:
Principle #23Feedback

2Object-affected harmful factors

If mesh routers remain in normal mode to ensure network security monitoring, then security threats can be detected, but energy wastage occurs when the environment is unoccupied

Engineering Contradiction:
Improvesecurity threat detectionVSAvoidpower wastage
Core Design Contradiction:
Object-affected harmful factorsVSLoss of energy

Solution Approach 1:

The system dynamically changes router operational modes based on occupancy status. When the sensing module detects an unoccupied environment, the controller switches routers to energy-saving mode, reducing power consumption while maintaining security monitoring capability through periodic or event-triggered detection rather than continuous operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Instead of continuous operation, the system employs periodic sensing and event-triggered router activation. The sensing module periodically checks for user presence, and routers are activated only when occupancy is detected, transforming continuous energy consumption into periodic, demand-based operation that maintains security while reducing overall energy wastage.

Inventive Principle:
Principle #19Periodic action

3Area of stationary object

If multiple mesh routers are deployed to extend wireless coverage, then network coverage area increases, but the complexity of network management increases

Engineering Contradiction:
Improvewireless coverage areaVSAvoidnetwork management complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The system merges the sensing and control functions into a centralized or coordinated mechanism where multiple mesh routers work under a unified management framework. The sensing module and controller coordinate across multiple routers, allowing them to operate independently for coverage extension while being collectively managed through a single occupancy detection system, thereby reducing management complexity despite increased network scale.

Inventive Principle:
Principle #5Merging (Combining)
