Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Interchangeable-lens cameras face challenges in efficiently changing photographing composition and implementing zoom-in/out functions when the camera body and lens unit are separated, as composition adjustments and focal distance changes are difficult without direct mechanical control over the lens unit.

Innovation Solution

Incorporating a moving trace measuring device, such as a gyroscope or acceleration sensor, in both the wireless lens unit and the main body to measure and transmit inclination and movement data via wireless modules, allowing the image processor to rotate and zoom image data accordingly, enabling efficient composition control and zoom functions even when the units are separated.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the camera body and lens unit are separated for wireless operation, then user flexibility and portability are improved, but composition control and zoom functions become difficult to implement

Engineering Contradiction:

Improvewireless operation capabilityVSAvoidcomposition control

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical control system with a wireless control system. The camera body transmits control signals wirelessly to the lens unit, and the lens unit feeds back operational status wirelessly to the camera body, eliminating the need for physical connection while maintaining full control functionality including composition adjustment and zoom operations

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a wireless communication module as an intermediary between the camera body and lens unit. This module handles the transmission of control signals and data, enabling the camera body to control the lens unit's composition and focal length without direct mechanical contact

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the camera body and lens unit are separated for wireless operation, then user flexibility and portability are improved, but focal distance adjustment becomes difficult

Engineering Contradiction:

Improvewireless operation capabilityVSAvoidfocal distance adjustment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical focal length adjustment with wireless control. The camera body sends focal distance adjustment commands wirelessly to the lens unit, which executes the zoom operations and returns status information wirelessly, maintaining full zoom functionality without physical connection

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If motion detection and image conversion processing are added to handle separated operation, then photographing capability in separated state is improved, but device complexity increases

Engineering Contradiction:
