Camera Grip Layout to Prevent User State Sensor Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image pickup apparatuses face issues where the camera unit can be unintentionally covered by the user's hand, compromising its performance despite using high-performance components.
Innovation Solution
The image pickup apparatus is designed with a specific layout that includes a user state detection unit and gripping portions to prevent the detection unit from being blocked by the user's hand, featuring a horizontally long rectangular display unit and strategically positioned gripping portions connected via housing surfaces, with the detection unit placed to avoid obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera unit is positioned on the rear surface of the housing, then it can capture images of the user, but the camera unit may be unintentionally covered by the user's hand during operation
Solution Approach 1:
The patent positions the camera unit on the rear surface of the housing (a different spatial dimension relative to the display), and strategically places gripping portions on the front and side surfaces. This spatial arrangement ensures that when the user grips the device from the front, their hand does not obstruct the rear-facing camera, thus resolving the contradiction between camera accessibility and hand obstruction.
2Ease of operation
If the display unit is made horizontally long rectangular, then it provides better user interface, but the detection unit placement becomes more critical to avoid hand blocking
Solution Approach 1:
The patent employs asymmetric placement of the detection unit relative to the horizontally long rectangular display. The detection unit is positioned at a specific location that is closer to one edge than the other, strategically chosen to fall outside the typical hand gripping zone. This asymmetric positioning allows the display to maintain its horizontally long rectangular shape for better UI while ensuring the detection unit remains unobstructed during normal operation.
3Ease of operation
If gripping portions are added to the housing, then ease of holding is improved, but the layout complexity increases
Solution Approach 1:
The patent integrates gripping portions into the housing structure in a way that serves multiple functions: they provide ergonomic gripping surfaces for the user, define the spatial boundaries that protect the camera and detection unit from obstruction, and maintain the overall aesthetic design. By making the gripping portions an integral part of the housing rather than separate components, the patent minimizes layout complexity while achieving improved gripping comfort.

AI summary
An image pickup apparatus having a layout preventing a detection unit from being blocked is provided. The image pickup apparatus including a housing and a display unit disposed on a rear surface of the housing includes a user state detection unit to detect a state of a user, a rear surface gripping portion disposed on a right side on a substantial extension line in a longitudinal direction of the display unit, and a front surface gripping portion disposed on a front surface of the housing and corresponding to the rear surface gripping portion. The user state detection unit is disposed at a position closer to a left side of the display unit than to a right side thereof and preventing a detection range of the user state detection unit from being blocked by a hand of the user when the user grips and operates the image pickup apparatus.
