Solution Overview

Problem

Existing articles of clothing fail to predict user discomfort and modulate the internal microclimate effectively, leading to issues such as cold, overheating, or sweat, and often compromise on fashion and comfort.

Innovation Solution

An article of clothing with integrated humidity and temperature sensors, a controller, and microclimate control elements that adjust the internal environment to maintain a comfort threshold, using heating, cooling, or air flow, to prevent discomfort before it is perceived by the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If insulation is made thicker to protect from cold, then thermal protection is improved, but the article becomes heavier and less flexible

Engineering Contradiction:
Improvethermal protectionVSAvoidarticle weight
Core Design Contradiction:
TemperatureVSWeight of moving object

Solution Approach 1:

The patent changes the thermal protection approach from passive thick insulation to active thermal management by adjusting insulation properties dynamically. The article uses controllable insulation elements that can be activated or deactivated based on real-time temperature and humidity sensor data, allowing thin baseline insulation to provide adequate protection without the weight of thick permanent insulation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamic insulation adjustment where the insulation properties of the article can be changed in real-time based on environmental conditions and user activity levels. Sensors continuously monitor temperature and humidity, and the controller adjusts insulation elements accordingly, transforming static thick insulation into adaptive dynamic insulation that provides equivalent protection with reduced weight.

Inventive Principle:
Principle #15Dynamics

2Temperature

If insulation is made thicker to protect from cold, then thermal protection is improved, but flexibility and comfort are reduced

Engineering Contradiction:
Improvethermal protectionVSAvoidflexibility and comfort
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The patent transforms static insulation into dynamically adjustable insulation properties. By using controllable insulation elements that can be activated only when needed, the article maintains flexibility and comfort during normal activity while providing thermal protection when conditions require it, based on real-time sensor feedback.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamic adjustment of insulation properties to balance protection and comfort. The system monitors environmental conditions and user physiology, then adjusts insulation in real-time, allowing the article to transition between flexible/comfortable state and protected state as needed.

Inventive Principle:
Principle #15Dynamics

3Temperature

If heating elements are added to provide warmth, then thermal protection is improved, but device complexity increases

Engineering Contradiction:
Improvethermal protectionVSAvoidsystem complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent implements a self-regulating thermal management system where sensors automatically detect temperature and humidity conditions, and the controller autonomously adjusts insulation elements without user intervention. This self-service approach provides thermal protection while minimizing complexity by eliminating the need for manual controls, buttons, or complex user interfaces.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent incorporates a feedback loop where temperature and humidity sensors continuously monitor conditions, and the controller uses this feedback to automatically adjust insulation elements. This closed-loop control system provides effective thermal protection while keeping the system relatively simple through automated decision-making based on sensor inputs.

Inventive Principle:
Principle #23Feedback

4Ease of operation

If sensors and control systems are integrated to predict discomfort, then user comfort is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveuser comfortVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent combines multiple functions (sensing, processing, and control) into an integrated system where temperature and humidity sensors, microcontroller, and insulation control elements work as a unified assembly. This merging of functions improves user comfort through predictive discomfort detection while managing manufacturing complexity by reducing the number of separate components and assembly steps.

Inventive Principle:
Principle #5Merging (Combining)
