Rotatable Camera Grip With Triangular Key Layout for Compact Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing apparatuses face challenges in reducing grip size while maintaining operability and holdability, as conventional designs increase the distance between the body and grasping portion, leading to increased load and reduced operability.
Innovation Solution
A rotatable grip design with operation elements positioned to minimize the grip's size and load on the user, featuring a triangular key arrangement and distinct exterior coverage to enhance operability and reduce overall dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the arm and operation keys are arranged between the image capturing apparatus body and the grasping portion, then the operation keys can be accessed, but the distance between the body and grasping portion increases, making it difficult to reduce the size of the whole apparatus
Solution Approach 1:
The operation keys are arranged in a triangular configuration with the third operation key positioned between the first and second operation keys in the upward direction. This triangular arrangement allows compact positioning of multiple keys within a limited space, enabling access to all keys without increasing the overall grip length in the horizontal direction.
Solution Approach 2:
The grip is designed to be rotatable relative to the image capturing apparatus body, allowing the user to adjust the orientation of the operation keys to convenient positions. This rotational flexibility enables compact key arrangement while maintaining ease of operation through adjustable positioning.
2Ease of operation
If the arm and operation keys are arranged between the image capturing apparatus body and the grasping portion, then the operation keys can be accessed, but the load felt by the user in the direction orthogonal to the optical axis increases, reducing operability
Solution Approach 1:
By arranging operation keys in a triangular pattern with vertical stacking (first, second, and third operation keys positioned at different heights), the design utilizes the vertical dimension to accommodate multiple keys without extending the horizontal grip length. This reduces the moment arm and consequently the load felt by the user in the direction orthogonal to the optical axis.
Solution Approach 2:
The grip exterior is designed with differentiated coverage: the first exterior covers the first operation key while the second exterior covers the third operation key, creating localized protective and ergonomic zones. This localized design allows compact key arrangement while maintaining comfortable hand positioning, thereby reducing the overall load on the user.
3Adaptability or versatility
If the grip size is reduced and many operation keys are arranged, then the operability and function are improved, but it becomes difficult to ensure holdability and operability
Solution Approach 1:
The triangular arrangement of operation keys utilizes three-dimensional space (horizontal and vertical positions) to accommodate multiple keys within a compact grip footprint. This allows numerous functionally important keys to be included without increasing the grip's overall volume, maintaining both functionality and holdability.
Solution Approach 2:
The asymmetric triangular arrangement of operation keys optimizes the distribution of controls within the grip. By positioning keys at different heights and horizontal locations in an asymmetric pattern, the design achieves compact packaging while maintaining ergonomic accessibility for the user's thumb and fingers.

AI summary
An image capturing apparatus including an image capturing apparatus body and a grip rotatably attached to a side surface of the body. The grip includes a grasping portion for being grasped by a user, a first, a second, and a third operation keys for being operated by the user, a lower grip exterior portion covering the first operation key at least from the body, and an upper grip exterior portion covering the third operation key at least from the body. When the grip is in a position where the first and second operation keys are upward of the grasping portion, the third operation key is upward of a line segment connecting between the first and second operation keys, and at the same time, the upper grip exterior portion is more remote from the body than the lower grip exterior portion.
