Solution Overview

Problem

The challenge lies in designing a mobile terminal that is both lightweight and thin while maintaining better performance, as these goals often constrain each other, leading to a design plateau.

Innovation Solution

A mobile terminal is designed with a detachable hand-held portion and body portion, where the hand-held portion includes a wireless communication module, power module, and display screen, and the body portion includes a camera module and additional wireless communication modules. The hand-held portion can be detached and receive signals from the body portion, allowing for a simplified structure, reduced power consumption, and improved runtime, while the body portion can house a larger battery for extended use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the mobile phone is made lighter and thinner, then the portability is improved, but the performance and runtime are worsened due to limited space for battery and components

Engineering Contradiction:
Improvethickness of mobile phoneVSAvoidruntime of mobile phone
Core Design Contradiction:
Length of moving objectVSDuration of action of moving object

Solution Approach 1:

The mobile phone is divided into two separable parts: a hand-held portion containing the display screen and basic communication functions, and a body portion containing the camera module and battery. This segmentation allows the hand-held portion to be thin and lightweight while the body portion houses the larger battery for extended runtime, resolving the contradiction between thinness and runtime.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If more components are added to improve performance, then the functionality is enhanced, but the device complexity and power consumption increase

Engineering Contradiction:
Improvefunctionality of mobile phoneVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By separating the mobile phone into hand-held portion and body portion, each with specific functions, the design achieves enhanced functionality (camera, display, communication) while keeping each module relatively simple. The hand-held portion contains essential communication and display functions, while the body portion contains camera and battery, reducing overall system complexity through functional distribution.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wireless communication modules in both hand-held portion and body portion enable the device to function independently or in combination. The hand-held portion can operate as a standalone communication device, while attaching the body portion adds camera and extended battery functions, providing multi-functionality without requiring all components to be integrated in one unit.

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

3Adaptability or versatility

If more components are added to improve performance, then the functionality is enhanced, but the weight of the device increases

Engineering Contradiction:
Improvefunctionality of mobile phoneVSAvoidweight of mobile phone
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The mobile phone is divided into two separable parts: a hand-held portion containing the display screen and basic communication functions, and a body portion containing the camera module and battery. This segmentation allows the hand-held portion to be thin and lightweight while the body portion houses the larger battery for extended runtime, resolving the contradiction between thinness and runtime.

Inventive Principle:
Principle #1Segmentation

4Ease of manufacture

If the hand-held portion has a simplified structure with fewer components, then the manufacturing cost is reduced and runtime is improved, but the functionality is limited

Engineering Contradiction:
Improvemanufacturing costVSAvoidfunctionality of hand-held portion
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The wireless communication modules in both hand-held portion and body portion enable the device to function independently or in combination. The hand-held portion can operate as a standalone communication device, while attaching the body portion adds camera and extended battery functions, providing multi-functionality without requiring all components to be integrated in one unit.

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

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design enables a thin and lightweight hand-held portion with improved runtime, reduced manufacturing costs, and enhanced performance by allowing the body portion to have a larger battery, while maintaining ease of use and connectivity.

Implementation Method 1

the spring button must be configured to be elastic, such that the spring button may not protrude out of the side wall of the receiving space when the external force (the pressing) is applied to the button
