Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The periscope camera in mobile devices faces challenges with static electricity protection and interference, and existing optical anti-shake methods require a separate camera gyroscope, increasing the size of the imaging module and limiting its compactness.

Innovation Solution

The camera assembly and gyroscope are disposed separately, with the gyroscope positioned in the sliding module to detect camera shake, allowing for optical anti-shake shooting while reducing the module's size, and a reinforcing plate on the module circuit board connects the housing to ground the iron shell for static protection without increasing volume.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conductive cloth or copper foil is added to ground the iron shell, then static electricity protection is improved, but the imaging module size increases and space is insufficient

Engineering Contradiction:

Improvestatic electricity protectionVSAvoidimaging module size

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent combines the grounding function with the existing reinforcing plate structure. The reinforcing plate, which is already present for structural support, is equipped with a ground pin to perform grounding function, eliminating the need for separate conductive cloth or copper foil and thus avoiding additional volume.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The reinforcing plate serves dual purposes: structural reinforcement and static electricity grounding. By integrating the grounding function into an existing structural component, the patent avoids adding separate grounding materials that would increase module size.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a separate camera gyroscope is added for optical anti-shake, then image stabilization is improved, but the imaging module size increases

Engineering Contradiction:

Improveimage stabilizationVSAvoidimaging module size

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent extracts the gyroscope from the imaging module and places it in the sliding module. This separation allows the imaging module to maintain a compact size while still achieving optical anti-shake functionality through the gyroscope's detection capability in the sliding module.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent moves the gyroscope to a different spatial location (the sliding module) rather than including it within the imaging module. This dimensional repositioning resolves the space conflict by utilizing volume in a different spatial zone.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
