Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the vehicle climate control system uses standard temperature sensors to measure air temperature, then the system can control cabin air temperature, but the system cannot detect surface temperatures of objects which may be potentially dangerous

Engineering Contradiction:
Improvesurface temperature detection capabilityVSAvoidtemperature sensing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the temperature monitoring function into multiple temperature sensors positioned at different locations within the vehicle cabin. Each sensor monitors specific zones (seats, armrests, center console, steering wheel) independently, allowing the system to detect surface temperatures across multiple critical surfaces simultaneously without requiring a single complex sensing mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control module serves as an intermediary that receives temperature data from multiple sensors, processes the information, and coordinates the climate control system's response. This intermediary component integrates the sensing data and manages the selective cooling airflow distribution without requiring direct complex interaction between sensors and climate control actuators.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the climate control system cools the entire cabin to reduce object surface temperatures, then dangerous surface temperatures are reduced, but energy consumption increases and cooling efficiency decreases

Engineering Contradiction:
Improvedangerous surface temperaturesVSAvoidclimate control energy consumption
Core Design Contradiction:
Object-affected harmful factorsVSUse of energy by moving object

Solution Approach 1:

The system applies cooling selectively to specific zones within the cabin based on real-time temperature sensor data. When an object's surface temperature exceeds a threshold, the control module directs cooled airflow specifically to that object's location rather than cooling the entire cabin, thereby reducing energy consumption while still preventing dangerous surface temperatures.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system proactively detects when object surface temperatures are approaching dangerous levels and initiates targeted cooling before the temperatures become hazardous. This preliminary action prevents the need for more intensive cooling later, reducing overall energy consumption while maintaining safety.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the system continuously monitors all surface temperatures and provides alerts, then occupant safety is enhanced, but system complexity and processing requirements increase

Engineering Contradiction:
Improveoccupant safetyVSAvoidmonitoring and alert system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system monitors temperature continuously but only triggers alerts and cooling actions when temperature thresholds are exceeded. This partial action approach maintains continuous monitoring capability for safety while avoiding the complexity of processing and responding to all temperature data points, focusing resources only on hazardous conditions.

Inventive Principle:
Principle #16Partial or excessive action

4Measurement precision

If multiple temperature sensors are deployed throughout the vehicle, then surface temperature detection accuracy improves, but system cost and complexity increase

Engineering Contradiction:
Improvesurface temperature measurement accuracyVSAvoidsensor network complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent places multiple temperature sensors at specific critical locations within the cabin (seats, armrests, center console, steering wheel) rather than using a single comprehensive sensor. This segmentation approach achieves accurate surface temperature measurement across multiple objects using simple, distributed sensors that are easier to implement than a single complex sensing system.

Inventive Principle:
Principle #1Segmentation

AI summary

A vehicle system includes temperature sensors positioned in the vehicle and a control module in communication with the temperature sensors. The temperature sensors are configured to measure surface temperatures of objects in the vehicle. The control module is configured to receive the measured surface temperatures from the temperature sensors, determine whether any of the measured surface temperatures is greater than a defined threshold, and in response to any of the measured surface temperatures being greater than the defined threshold, transmit an alert signal to a user communication device indicative of the objects in the vehicle having the measured surface temperatures greater than the defined threshold.
