Solution Overview

Problem

Existing mobile phones face challenges with small display screens that are difficult to operate single-handedly due to their aspect ratio, leading to inefficient use of space, environmental waste from rapid phone replacements, and power limitations due to thinner designs.

Innovation Solution

A mobile power bank with a large, elongated display screen and integrated storage battery, allowing for a combined terminal device that can be joined with other mobile terminals to increase display area, eliminate black borders, and extend battery life without increasing thickness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the display screen area is increased to satisfy large display requirements, then the display area is improved, but the width becomes too large causing single-hand operation to fail

Engineering Contradiction:
Improvedisplay screen areaVSAvoidsingle-hand operation
Core Design Contradiction:
Area of moving objectVSEase of operation

Solution Approach 1:

The patent combines multiple mobile terminals into a combined terminal device, merging their display screens to create a larger effective display area while keeping each individual terminal's screen size manageable for single-hand operation. The terminals are arranged in specific patterns (e.g., 2×2 grid) to form a composite display that functions as a unified large screen device.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If the display screen is designed with conventional length-width ratio, then the design is simple, but black borders appear at the periphery affecting display effect and not realizing maximum utilization

Engineering Contradiction:
Improvedesign simplicityVSAvoiddisplay area utilization
Core Design Contradiction:
Ease of manufactureVSArea of stationary object

Solution Approach 1:

The patent transitions from conventional single-screen display to multi-screen combination, adding a spatial dimension to the display area. By arranging multiple screens in two-dimensional patterns (rows and columns), the system achieves A4 paper ratio display without black borders, maximizing display area utilization while maintaining design simplicity through modular assembly.

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

3Adaptability or versatility

If mobile phones are renewed rapidly to provide latest technology, then the technology is updated, but resource waste and environmental pollution increase

Engineering Contradiction:
Improvetechnology updateVSAvoidresource waste
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The patent enables recovery and reuse of older mobile terminals by incorporating them into combined terminal devices. Instead of discarding outdated phones, the system recovers their functional value by combining multiple units to create a new device type with enhanced capabilities, thereby reducing resource waste and environmental pollution from electronic waste.

Inventive Principle:
Principle #34Discarding and recovering

4Use of energy by moving object

If the battery size is increased to provide sufficient power, then the power supply is improved, but the device thickness increases which is not acceptable

Engineering Contradiction:
Improvepower supply capacityVSAvoiddevice thickness
Core Design Contradiction:
Use of energy by moving objectVSLength of stationary object

Solution Approach 1:

The patent segments the power supply function across multiple mobile terminals in the combined device. Each terminal contributes its own battery capacity to the overall system, providing sufficient total power without requiring any single terminal to have a large, thick battery. The distributed power architecture maintains thin profile while ensuring adequate energy supply.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention relates to a mobile terminal, and in particular to a mobile power bank and a combined terminal device formed by splicing the mobile power bank and the mobile terminal. The mobile power bank comprises a display screen, a storage battery located below the display screen, and a casing for holding the display screen and the storage battery. The mobile power bank is generally flat-plate shaped with a front surface and a back surface. Both an area of a display region of the display screen and an area of an occupied region of the storage battery are not less than 70% of the front surface area. A volume of the storage battery can be increased without changing the thickness of the storage battery, providing an extended charging service for mobile phones. In addition, the mobile power bank of the present invention has a large display screen, when the mobile power bank is connected to a mobile terminal, such as a mobile phone, the display screen and a display screen of the mobile terminal may perform display at the same time.
