Imaging Device Button Layout and Grip Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Imaging devices with integrated display capabilities face usability challenges due to complex button layouts and ergonomic design, leading to operational inefficiencies and increased risk of accidental button presses.
Innovation Solution
The imaging device features a shooting button positioned above a horizontal line on the outer case, with a zoom knob on the same side, and incorporates a large-diameter and small-diameter portion design with an inclined portion, placing frequently used buttons like the power and pop-up buttons in accessible locations, and using rolling prevention portions for stable grip and reduced accidental operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If buttons are placed on the outer case for easy access, then ease of operation is improved, but the risk of erroneous operation increases
Solution Approach 1:
The power button is specifically positioned on the small-diameter portion of the outer case, creating a localized area with different operational characteristics. This local differentiation allows the power button to be easily accessible while being spatially separated from other controls, reducing the likelihood of accidental presses during normal camera operations.
2Device complexity
If multiple buttons are placed close together for compact design, then device complexity is reduced, but the risk of accidental button presses increases
Solution Approach 1:
The outer case is divided into distinct diameter portions (large-diameter and small-diameter portions), creating spatial zones for different controls. This segmentation physically separates the power button from other buttons and controls, allowing compact overall design while maintaining adequate spacing to prevent accidental activation of wrong controls.
3Ease of manufacture
If the outer case has uniform diameter for simple manufacturing, then ease of manufacture is improved, but user grip stability deteriorates
Solution Approach 1:
The outer case features asymmetric diameter design with both large-diameter and small-diameter portions, providing varied grip surfaces that accommodate different hand sizes and gripping styles. This asymmetric geometry enhances user comfort and stability during operation while remaining manufacturable through standard molding techniques.

AI summary
There is provided an imaging device including an image sensor, and an outer case in which the image sensor is disposed. A shooting button configured to photograph a subject is disposed on an outer peripheral surface of the outer case. When an intersection line between a horizontal surface including a center of the outer case in a vertical direction and the outer peripheral surface of the outer case is set as a horizontal line, the shooting button is positioned close to the horizontal line above the horizontal line. A zoom knob configured to change photographic magnification is positioned on a same side as the shooting button in a horizontal direction.
