Solution Overview

Problem

The design of lightweight and thin mobile phones faces a bottleneck as performance demands increase, with traditional designs restricted by the need to balance thinness and functionality, particularly in incorporating essential components like display screens and fingerprint identification systems without compromising thickness and battery endurance.

Innovation Solution

A modular design featuring a master machine and a detachable slave machine, where the slave machine includes a display screen, main board, and fingerprint identification assembly with a power source unit, allowing for communication and power supply to these components, and a through-hole configuration for the identification unit to reduce thickness and overlap, enabling lightweight and thin development.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional mobile phone design is used to increase performance, then functionality is improved, but thickness and weight increase

Engineering Contradiction:
ImproveperformanceVSAvoidweight
Core Design Contradiction:
Adaptability or versatilityVSWeight of stationary object

Solution Approach 1:

The mobile phone is divided into two independent parts: a master machine containing communication modules and a slave machine containing display and fingerprint recognition modules. Each part has its own power source and can function independently or in combination, allowing performance enhancement without proportionally increasing overall weight.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The slave machine is designed to be detachably mounted to the master machine, creating a modular configuration that adds functionality in a dimensional sense rather than simply expanding the traditional single-unit structure. This allows performance enhancement without linearly increasing thickness.

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

2Adaptability or versatility

If traditional mobile phone design is used to increase performance, then functionality is improved, but thickness increases

Engineering Contradiction:
ImproveperformanceVSAvoidthickness
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

By segmenting the phone into master and slave machines with distinct functional modules, each component can be optimized for minimal thickness in its specific area, rather than uniformly increasing thickness across the entire device to accommodate all components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The slave machine can be detachably mounted to the master machine in a nested configuration, allowing components to be arranged in three-dimensional space efficiently without linearly increasing the overall thickness of the device.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Duration of action of moving object

If a detachable slave machine is added, then battery endurance is improved, but device complexity increases

Engineering Contradiction:
Improvebattery enduranceVSAvoidcomplexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The master and slave machines are designed with universal interfaces and communication protocols that allow them to work together as a unified system. The slave machine can function independently or attach to the master machine, providing multiple operational modes without requiring complex control logic.

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

Solution Approach 2:

Each machine has its own power source and can operate independently. The slave machine includes its own display, fingerprint recognition, and processing capabilities, reducing the need for complex inter-dependencies and control mechanisms between the two parts.

Inventive Principle:
Principle #25Self-service

AI summary

A mobile phone includes a master machine and a slave machine. The master machine includes a first power source unit; the slave machine includes a second power source unit, a display screen, a main board and a fingerprint identification assembly. The slave machine is able to be mounted to the master machine and detached from the master machine. When the slave machine is detached from the master machine, the slave machine is able to be in communication connection with the master machine. The main board is provided with a first through hole, the fingerprint identification assembly includes a connecting circuit board and an identification unit, the identification unit is able to be in communication connection with the main board through the connecting circuit board, and the identification unit is inserted into the first through hole. The present application further provides a slave machine.
