Problem

Conventional photographing devices do not consider factors such as heat and magnetism that can affect their operation, leading to potential performance issues and image quality degradation.

Innovation Solution

A camera device design that incorporates a heat release plate within a metal housing to manage heat generation and uses a non-metal housing for components sensitive to magnetism, allowing for efficient heat dissipation and reduced magnetic interference, enabling operation in both combined and detached states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a metal housing is used for structural strength and heat dissipation, then heat release is improved, but magnetic interference increases

Engineering Contradiction:
Improveheat dissipationVSAvoidmagnetic interference
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The housing is divided into two separate units: a first housing made of metal for heat dissipation and a second housing made of non-metal material for magnetic shielding. This segmentation allows each material to perform its optimal function without the drawbacks of the other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different parts of the overall housing structure are assigned different material properties - the first housing uses metal with high thermal conductivity for heat release, while the second housing uses non-metal material with magnetic shielding properties. Each local region has the quality needed for its specific function.

Inventive Principle:
Principle #3Local quality

2Device complexity

If components are placed in a single housing, then device complexity is reduced, but heat management and magnetic shielding cannot be optimized simultaneously

Engineering Contradiction:
Improvehousing structureVSAvoidoperational reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The device is divided into two detachable housing units that can function separately or combine. This segmentation enables optimized heat management and magnetic shielding in each unit while maintaining operational flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The two housing units can operate independently or combine to form a complete device. When combined, they provide both heat dissipation and magnetic shielding functions. This multi-functionality allows the system to adapt to different operational requirements.

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

3Object-affected harmful factors

If heat-generating components are isolated from the housing, then magnetic interference is reduced, but heat dissipation efficiency decreases

Engineering Contradiction:
Improvemagnetic interferenceVSAvoidheat dissipation efficiency
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

Heat-generating components are placed in the metal first housing for efficient heat dissipation, while magnetically sensitive components are placed in the non-metal second housing for magnetic shielding. This spatial segmentation resolves both requirements simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable second housing acts as an intermediary that provides magnetic shielding for sensitive components without interfering with the heat dissipation function of the first housing. When attached, it creates a composite structure that manages both heat and magnetic fields effectively.

Inventive Principle:
Principle #24Intermediary (Mediator)
