Camera Grip Surface Shape for Lateral Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera grip designs often lack effective grip performance, particularly when uneven, leading to slippage during use.
Innovation Solution
The design incorporates a grip portion with a surface shape featuring multiple three-dimensional surface shape portions arranged in a repeating pattern, including first, second, and third shape portions extending in different directions, which generate a lifting force when gripped laterally, enhancing grip security and preventing slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple smooth grip surface is used, then the manufacturing process is simple, but the grip performance is poor and slippage occurs during use
Solution Approach 1:
The grip portion incorporates localized three-dimensional surface shape portions (protrusions and recesses) on specific regions of the grip surface, while other areas remain smooth. This local modification provides enhanced grip performance exactly where the user's fingers contact the device, without complicating the overall manufacturing process or other areas of the device.
Solution Approach 2:
The invention transitions from a two-dimensional smooth surface to a three-dimensional textured surface by adding height and depth variations through protrusions and recesses. This dimensional change creates multiple contact points with the user's fingers, significantly improving grip performance while maintaining compatibility with standard molding processes.
2Reliability
If unevenness is added to the grip portion by etching, then grip performance is improved, but the manufacturing complexity increases
Solution Approach 1:
The invention modifies the surface geometry parameters by introducing three-dimensional protrusions and recesses with specific heights, widths, and spacing. These parameter changes are integrated into the molding process itself, allowing the complex surface geometry to be created in a single manufacturing step without requiring additional etching or post-processing operations.
Solution Approach 2:
The invention combines the grip texture creation with the base device molding process into a single integrated operation. The three-dimensional surface shape portions are formed simultaneously with the device body in one molding cycle, merging what would traditionally be separate manufacturing steps (base molding + surface texturing) into a unified process that reduces overall complexity.
3Device complexity
If a flat grip surface is used, then the structure is simple, but the grip security is poor when gripped laterally
Solution Approach 1:
The three-dimensional surface shape portions are configured with asymmetric patterns of protrusions and recesses that specifically address lateral gripping forces. The asymmetric geometry creates corresponding asymmetric force distribution when the device is gripped from the side, with the raised portions contacting the fingers to prevent slippage in lateral directions while maintaining structural simplicity in the overall device design.
