Solution Overview

Problem

Conventional jackets rely on bulkiness and layering for heat retention, restricting movement and taking time to provide warmth, and are often limited to specific occasions, requiring multiple jackets for different uses.

Innovation Solution

A jacket with an active heating system integrated into the main body, featuring three heating units in the neck, waist, and abdomen sections, connected to an external power supply, offering adjustable temperature settings and a boost mode for efficient warmth distribution, made from recycled materials with optional insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional jacket uses heat-retaining fabric and layering to optimize warming effect, then warming effect is improved, but the jacket becomes bulky and heavy restricting movement

Engineering Contradiction:

Improvewarming effectVSAvoidjacket weight

Core Design Contradiction:

TemperatureVSWeight of moving object

Solution Approach 1:

The patent replaces the mechanical/physical system of thick heat-retaining fabric and layering with an active heating system that uses electrical heating elements to generate warmth. This substitution allows the jacket to provide effective warming without requiring bulky insulation layers, thereby reducing weight and improving mobility while maintaining the primary function of heat retention through active thermal generation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Temperature

If conventional jacket uses heat-retaining fabric and layering to optimize warming effect, then warming effect is improved, but the jacket becomes bulky restricting movement

Engineering Contradiction:

Improvewarming effectVSAvoidjacket volume

Core Design Contradiction:

TemperatureVSVolume of moving object

Solution Approach 1:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of time

If conventional jacket only retains heat generated by wearer, then structure is simple, but wearer has to wait a fair amount of time to feel warming effect

Engineering Contradiction:

Improvetime to feel warmthVSAvoidenergy consumption

Core Design Contradiction:

Loss of timeVSUse of energy by moving object

Solution Approach 1:

The patent implements preliminary action by using heating elements that can actively generate and transfer heat to the wearer immediately upon activation, rather than relying on the wearer's body heat to gradually warm the jacket. This allows the warming effect to begin instantly or near-instantly, significantly reducing the time delay before the wearer feels warmth, while the system manages energy consumption through controlled heating zones and adjustable settings.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If conventional jacket is designed for cold weather outdoor use, then warming performance is optimized, but it performs poorly as indoor casual wear

Engineering Contradiction:

Improveoccasion suitabilityVSAvoidwarming performance

Core Design Contradiction:

Adaptability or versatilityVSTemperature

Solution Approach 1:

The patent applies dynamics by making the heating system adjustable and controllable, allowing the wearer to modify the warming level according to different environments and occasions. The jacket can be worn with heating elements activated for cold outdoor conditions, and the heating can be reduced or turned off for milder indoor environments, providing adaptability across various scenarios while maintaining appropriate thermal comfort levels.

Inventive Principle:

Principle #15Dynamics

AI summary

A jacket includes a main jacket body and an active heating system. The main jacket body is adapted for covering at least part of the body of a user, and has a neck section adapted to be disposed proximate to the neck of the user, a waist section adapted to be disposed proximate to the waist and lower back of the user, and at least one abdomen section adapted to be disposed proximate to the abdomen of the user. The active heating system is disposed in the main jacket body, is adapted for generating and transferring heat to the user, and includes at least three heating units. Each of the heating units is disposed in a respective one of the neck section, the waist section and the abdomen section of the main jacket body.
