Solution Overview

Problem

Existing apparel technologies fail to effectively protect wearers from harmful sun exposure and overheating by not providing a customizable and efficient method for selective deposition of reflective materials based on sun exposure patterns.

Innovation Solution

A system and method for selectively applying reflective materials on apparel using 3D human body modeling to determine areas of sun exposure, allowing for continuous and gradient applications of reflective materials on specific zones of the garment, utilizing metallic, metallized, or non-metallic substances to reflect visible and non-visible light.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If reflective materials are applied uniformly across the entire garment, then sun protection coverage is maximized, but material cost and weight increase

Engineering Contradiction:
Improvesun exposure protectionVSAvoidreflective material quantity
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The patent applies reflective materials selectively to specific zones of the garment based on sun exposure patterns rather than uniformly across the entire surface. The system identifies high-exposure areas (shoulders, upper back, arms) and applies reflective material primarily to these regions, creating local variations in material distribution that optimize protection while reducing overall material quantity and cost.

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If reflective materials are applied to all areas of the garment, then sun protection is comprehensive, but heat management efficiency decreases

Engineering Contradiction:
Improvesun exposure protectionVSAvoidheat management
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The patent creates zones of different reflective material concentrations corresponding to different sun exposure levels. High-exposure areas receive full reflective coating for maximum protection, while low-exposure areas receive reduced or no reflective material, allowing better heat dissipation and breathability in those regions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The garment surface is divided into multiple zones based on sun exposure patterns (high, medium, low exposure areas). Each zone receives appropriate reflective material treatment, with clear segmentation between protected areas and areas requiring thermal management, optimizing both protection and heat regulation.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If selective deposition based on 3D modeling is implemented, then material application precision is improved, but manufacturing process complexity increases

Engineering Contradiction:
Improvematerial deposition precisionVSAvoidmanufacturing system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent uses 3D modeling and sun exposure analysis to pre-determine the optimal zones for reflective material application before manufacturing. The system creates a digital map of sun exposure patterns on the garment, allowing precise material deposition planning in advance, which guides the manufacturing process and ensures accurate application to high-exposure areas.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a digital 3D model and sun exposure map that serves as a template or copy of the ideal material distribution pattern. This digital representation is then used to guide the physical material application process, transferring the optimized design from virtual space to physical garment with high precision.

Inventive Principle:
Principle #26Copying
