Digital Camera Grip Lever for One-Handed Image Advancement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital cameras require users to remove their hand from the grip to operate switching buttons or dials for image advancement, which is inconvenient and troublesome, especially when using touch panels.
Innovation Solution
A digital camera design featuring a lever that allows image feed without removing the hand from the grip, using a processor to hide and display alternate images in response to lever operation, with a locking mechanism and biasing member for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a switching button or operation dial is operated to check past images, then image advancement is achieved, but the user must remove hand from the grip which is inconvenient
Solution Approach 1:
The patent merges the grip portion with the operation member (dial) into a single integrated structure. The dial is positioned on the grip portion such that the user can operate it with the thumb while maintaining grip, eliminating the need to remove the hand from the grip. This combines the function of gripping with the function of operating controls.
Solution Approach 2:
The grip portion is designed to serve dual purposes: it provides the necessary grip for holding the camera and simultaneously houses the operation member for image advancement. This self-service design allows the same structure to perform multiple functions without requiring additional separate components.
2Ease of operation
If a touch panel is used for image feed, then image advancement is achieved, but the hand must be taken off the grip which is very troublesome
Solution Approach 1:
The operation member is integrated into the grip portion, allowing users to perform image feed operations with their thumb while maintaining a secure grip. This eliminates the time loss associated with removing and repositioning the hand that would occur with touch panel operation.
3Ease of operation
If the first member protrudes from the outer shape of the camera body, then the dial is accessible for operation, but the camera body shape is altered
Solution Approach 1:
The dial is positioned asymmetrically on the grip portion, protruding only where necessary for operational accessibility while maintaining a streamlined overall camera body shape. The protrusion is localized to the grip area where it does not significantly alter the aesthetic or aerodynamic profile of the camera.

AI summary
A digital camera includes a grip portion that is provided in a camera body, a lever that is provided in an end portion of the grip portion, a display that displays a captured image obtained by capturing an object image, and a processor. The processor is configured to hide at least a portion of a first captured image displayed on the display and to display a second captured image different from the first captured image on the display in response to an operation of the lever.
