Solution Overview

Problem

Pedestrians, especially children, are difficult to see in dusk or dark conditions, increasing the risk of being struck by vehicles, and conventional safety measures are often bulky or ineffective for those outside protected areas.

Innovation Solution

A visibility-enhancing system integrated with backpacks and carriers, featuring reflective elements and detachable light sources that extend beyond the container's perimeter, enhancing visibility to motorists through LED lights and reflective feathers, which can be easily attached and detached for appeal and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional safety measures (crossing guards, lit crosswalks) are implemented, then pedestrian safety is improved, but device complexity and bulk increase

Engineering Contradiction:
Improvepedestrian safetyVSAvoidsafety measure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The safety system is segmented into modular components: a backpack container, detachable visibility portions, and connector mechanisms. This allows the safety function to be distributed across multiple components rather than requiring a single complex system, enabling children to carry safety features without burden

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The visibility portions are designed to be detachable and reconfigurable, allowing dynamic adjustment based on needs. The connectors enable easy attachment and detachment, transforming the safety system from a static bulky structure to a flexible, adaptable solution that can be configured for different situations

Inventive Principle:
Principle #15Dynamics

2Illumination intensity

If visibility-enhancing portions extend beyond container perimeter, then visibility is improved, but device complexity increases

Engineering Contradiction:
ImprovevisibilityVSAvoidstructure complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The visibility portions extend in three-dimensional space beyond the two-dimensional container perimeter, creating outward-protruding elements that increase visibility without significantly increasing the footprint or complexity of the base container structure

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The visibility portions are nested within or attached to the container structure, with connectors enabling the portions to be integrated into the backpack system. This nesting approach allows visibility features to be added without proportionally increasing overall structural complexity

Inventive Principle:
Principle #7Nested doll (Nesting)

3Illumination intensity

If reflective elements and light sources are added, then visibility is improved, but weight increases

Engineering Contradiction:
ImprovevisibilityVSAvoidbackpack weight
Core Design Contradiction:
Illumination intensityVSWeight of moving object

Solution Approach 1:

Reflective elements and light sources are applied locally at specific positions on the visibility portions rather than uniformly across the entire backpack. This localized application maximizes visibility effectiveness while minimizing the total weight of reflective and lighting materials

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The visibility-enhancing elements (reflective portions, light sources) are extracted as separate detachable components rather than being permanently integrated into the backpack structure. This extraction allows the backpack base to remain lightweight while adding visibility features only when needed

Inventive Principle:
Principle #2Taking out (Extraction)
