Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional hazard detection devices use single power source with limited power capacity, then the device can maintain simple structure and reliable operation, but it cannot integrate additional security and communication features

Engineering Contradiction:

Improveintegration of security and communication featuresVSAvoidpower management system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hazard detection device is designed to perform multiple functions including hazard detection, security monitoring, and communication. By integrating these diverse functions into a single device, the patent achieves versatility without proportionally increasing complexity, as the power management system handles multiple power sources uniformly

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The power management system dynamically allocates power between different functions (hazard detection, security, communication) based on availability and priority. This dynamic power distribution allows the device to adapt its functionality in real-time while maintaining manageable complexity through automated control

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If hazard detection device integrates multiple functions with additional power sources, then the device can provide comprehensive safety and security monitoring, but it risks power instability and interruption

Engineering Contradiction:

Improvecomprehensive safety and security monitoringVSAvoidpower stability and continuous operation

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system incorporates a backup battery that is charged in advance during periods when primary power sources are available. This pre-charged battery serves as a cushion that kicks in automatically when primary power sources fail, ensuring continuous operation of critical hazard detection functions without interruption

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The power management system continuously monitors the status of multiple power sources and dynamically adjusts power allocation based on real-time conditions. This feedback mechanism ensures that power is drawn from the most reliable sources available and switches automatically to backup sources when needed, maintaining system reliability

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If power is allocated to ancillary security and communication functions, then the device gains enhanced capabilities, but the primary hazard detection function may suffer from power insufficiency

Engineering Contradiction:

Improveancillary security and communication functionsVSAvoidprimary hazard detection function reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system implements a power allocation strategy where ancillary functions (security and communication) receive power only when sufficient power is available after ensuring the primary hazard detection function has adequate power. This partial action approach allows enhanced capabilities without compromising the reliability of the primary safety function

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The device segments functions into primary (hazard detection) and secondary (security, communication) categories with different power priorities. This segmentation allows the power management system to allocate power hierarchically, ensuring critical safety functions always receive sufficient power while ancillary functions operate when power permits

Inventive Principle:

Principle #1Segmentation

AI summary

An enhanced hazard detection device has multiple sensors. A primary sensor continuously monitors for a hazard in a vicinity of the enhanced hazard detection device, and a secondary sensor can detect or measure a physical property in the vicinity of the enhanced hazard detection device. The enhanced hazard detection device can include communications circuitry to wirelessly couple the enhanced hazard detection device to a local network. A power management controller of the enhanced hazard detection device can dynamically manage usable power, where usable power for the secondary sensor and the communications circuitry is conditioned on sufficient usable power being available for the primary sensor. As such, the enhanced hazard detection device can monitor a change in usable power and, if necessary, divert usable power from most of the multiple sensors and/or the communications circuitry to the primary sensor, to maintain uninterrupted hazard detection.
