Problem

Portable electronic devices, such as mobile phones, have limited battery power supplies that are insufficient for extended use without recharging, especially in emergency situations or when access to charging sources is unavailable.

Innovation Solution

An apparatus with a rotatable housing that includes an integral electric generator, allowing the device to charge its battery through the rotation of one housing relative to another, enabling self-powering and continuous communication even without external power sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the battery capacity is increased to extend usage time, then the device weight and size increase, but portability and ease of carrying deteriorate

Engineering Contradiction:
Improvebattery usage durationVSAvoiddevice weight
Core Design Contradiction:
Duration of action of moving objectVSWeight of moving object

Solution Approach 1:

The device enables self-charging through manual rotation of the second housing, which drives the electric generator to produce electrical energy that charges the battery. This eliminates the need for external power sources and allows the device to replenish its own energy supply through user action.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces a rotatable second housing that can rotate relative to the first housing around a central axis. This dynamic mechanical structure converts manual rotational motion into electrical energy through the electric generator, providing a flexible energy generation mechanism that adapts to user input.

Inventive Principle:
Principle #15Dynamics

2Duration of action of moving object

If the battery capacity is increased to extend usage time, then the device volume increases, but compactness and portability deteriorate

Engineering Contradiction:
Improvebattery usage durationVSAvoiddevice volume
Core Design Contradiction:
Duration of action of moving objectVSVolume of moving object

Solution Approach 1:

The device enables self-charging through manual rotation of the second housing, which drives the electric generator to produce electrical energy that charges the battery. This eliminates the need for external power sources and allows the device to replenish its own energy supply through user action.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces a rotatable second housing that can rotate relative to the first housing around a central axis. This dynamic mechanical structure converts manual rotational motion into electrical energy through the electric generator, providing a flexible energy generation mechanism that adapts to user input.

Inventive Principle:
Principle #15Dynamics

3Extent of automation

If manual rotation is added to generate power, then the device can charge autonomously, but the device complexity increases

Engineering Contradiction:
Improveautonomous charging capabilityVSAvoidmechanical structure complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent combines the display screen with the second housing, integrating multiple functions into a single component. The touchscreen display serves both as the user interface and as part of the rotatable structure that drives the energy generation mechanism, reducing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The second housing serves multiple functions: it houses the display screen for user interaction, acts as the rotatable component that generates mechanical energy, and provides structural support for the electric generator. This multi-functionality reduces the need for separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
