Camera Grip Section Design for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compact digital cameras with high pixel numbers suffer from image quality deterioration due to hand shaking, exacerbated by their small size and design, which makes them difficult to grip securely, especially with smaller body panels and larger liquid crystal displays.
Innovation Solution
A camera design featuring a grip section bent backward on one lateral end of the base section, incorporating a curved surface and a slip-proof section with small projecting portions to enhance grip stability, along with strategically placed controls for improved operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the camera body size is reduced to make it compact, then portability is improved, but grip stability deteriorates
Solution Approach 1:
The camera body is divided into a base section and a grip section that are positioned at different locations. The grip section is bent backward relative to the base section, creating distinct functional zones that improve grip stability without increasing overall camera volume.
Solution Approach 2:
The grip section is bent backward in the lateral direction rather than extending the camera lengthwise. This dimensional change allows the grip section to be positioned away from the base section in the lateral dimension, improving grip stability while maintaining a compact overall size.
2Area of moving object
If the liquid crystal display size is increased to improve image viewing, then image display quality is improved, but the body panel section for gripping becomes smaller
Solution Approach 1:
The camera body is segmented into base and grip sections positioned at different locations. This segmentation allows the liquid crystal display to occupy more area on the base section while the grip section maintains sufficient surface area for stable gripping.
Solution Approach 2:
By bending the grip section backward in the lateral dimension, the design creates separate functional zones. This allows the liquid crystal display area on the base section to be enlarged without reducing the grip section's gripping surface area.
3Volume of moving object
If the camera body size is reduced to make it compact, then portability is improved, but hand shaking increases
Solution Approach 1:
Dividing the camera into base and grip sections positioned apart reduces the camera's moment of inertia around the grip axis. This segmentation allows for compact overall size while the separated grip section provides stable hand holding that minimizes hand shaking.
Solution Approach 2:
Positioning the grip section backward in the lateral dimension creates a compact camera body while the separated grip provides stable hand holding, reducing hand shaking despite the small size.
4Volume of moving object
If the body panel section except liquid crystal display is reduced to make the camera compact, then camera size is reduced, but operability deteriorates
Solution Approach 1:
The camera is segmented into base and grip sections with controls strategically placed on both sections. This segmentation allows compact overall size while distributing controls across different sections for improved operability.
Solution Approach 2:
Controls are strategically placed on different sections of the camera body, with each section having controls appropriate to its function. This local optimization of control placement maintains operability despite reduced overall camera size.

AI summary
A camera includes a base section, and a grip section which is provided in at least one lateral end of the camera, bending to a rear side of the camera. The grip section is disposed with a slip-proof section adjacent to a zoom key which is longitudinally arranged. Additionally, a slip-proof section to prevent finger slipping is positioned on a back surface of the grip section.
