Solution Overview

Problem

Public spaces often lack sufficient or appropriate power outlets to meet the increasing demand for charging portable electronic devices, due to aging infrastructure.

Innovation Solution

A portable power bank system that includes a docking station and a bag for carrying the power bank, along with a smartphone app for managing the system, providing wireless charging capabilities and multiple electrical receptacles, allowing for on-the-go charging of devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If power outlets are installed in public spaces, then charging availability is improved, but infrastructure complexity and installation cost increase

Engineering Contradiction:

Improvecharging availabilityVSAvoidinfrastructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides the charging function into separate components: a portable power bank unit and a docking station. The power bank can be carried independently and provides charging without requiring permanent infrastructure installation, while the docking station serves as a stationary base for recharging the power bank.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The charging capability is extracted from the fixed infrastructure (power outlets) and transferred to a portable device (power bank). This allows users to carry charging capacity with them rather than relying on installed outlets in public spaces.

Inventive Principle:

Principle #2Taking out (Extraction)

2Productivity

If more power outlets are installed, then charging demand is met, but installation cost and infrastructure investment increase

Engineering Contradiction:

Improvecharging demand fulfillmentVSAvoidinstallation cost

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The system enables users to carry their own charging capacity through portable power banks. Instead of requiring public spaces to provide charging infrastructure, users self-provide power through their personal power banks, eliminating the need for costly outlet installations.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If a portable power bank system is used, then charging portability is improved, but device complexity increases

Engineering Contradiction:

Improvecharging portabilityVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system combines the power bank and docking station into a coordinated unit where the docking station automatically charges the power bank when docked. This integration simplifies the user experience by providing automatic recharging functionality without requiring manual intervention.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The docking station serves multiple functions: it acts as a base for storing the power bank, a charging station for recharging the power bank, and potentially a pass-through charging point for electronic devices. This multi-functionality reduces the need for separate devices for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)
