Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing imaging devices struggle to quickly switch photographic settings when scenes change, leading to a risk of missing photographic opportunities.

Innovation Solution

An imaging device with a first button that assigns multiple photographic settings, allowing sequential switching between these settings with each button depression, including both user-assigned and device-default settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a button operation is used to apply a saved photographic setting, then the photographic setting can be applied to the imaging device, but it is difficult to further appropriately switch photographic settings when scenes are subsequently switched

Engineering Contradiction:

Improveapplication of photographic settingVSAvoidswitching of photographic settings

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The imaging device dynamically switches between multiple photographic settings based on the number of times the button is operated. The switching unit changes the applied setting from the initially saved setting to subsequently saved settings in sequence, allowing the system to adapt to different scenes through repeated button operations rather than requiring manual reconfiguration.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If conventional button operation is used for switching settings, then a single setting can be applied, but the user cannot quickly change to a photographic setting matching a scene when scenes are frequently switched

Engineering Contradiction:

Improvesetting applicationVSAvoidtime to change photographic setting

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The imaging device performs preliminary actions by saving multiple photographic settings in advance (first saved setting, second saved setting, etc.) and preparing them for sequential switching. When the button is operated multiple times, the switching unit quickly applies the next pre-saved setting without requiring the user to manually configure parameters, thereby reducing the time to adapt to frequently changing scenes.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If multiple photographic settings are saved and assigned to a button, then quick switching is enabled, but the device complexity increases

Engineering Contradiction:

Improvespeed of setting switchingVSAvoidsetting management system

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

A single button serves multiple functions: it acts as both the trigger for switching settings and the identifier for the sequence of settings. The switching unit universally manages multiple photographic settings (first saved setting, second saved setting, third saved setting) using the same button operation mechanism, avoiding the need for separate controls for each setting and thereby limiting the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An imaging device includes a first button to which at least one photographic setting is assigned in accordance with a user operation. The imaging device further includes switching unit which sequentially switches, each time the first button is depressed, a photographic setting to be applied to the imaging device from among a plurality of photographic settings including a photographic setting set to the imaging device and a photographic setting assigned to the first button.
