Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup apparatuses face issues where the camera unit can be unintentionally covered by the user's hand, hindering its performance despite using high-performance components.
Innovation Solution
The apparatus features a user state detection unit with a specific layout that prevents blocking by the user's hand, including a horizontally long rectangular display unit, rear and front surface gripping portions, and a user state detection unit positioned to avoid obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera unit is placed in a conventional position near the display unit, then the in-camera function can be achieved, but the camera unit is blocked by the user's hand during operation
Solution Approach 1:
The patent applies dimensionality change by moving the user state detection unit from a conventional position (near the display unit) to a corner position of the housing. This spatial repositioning in three-dimensional space allows the detection unit to detect user states without being blocked by the hand, while the camera unit remains functional. The corner positioning creates a geometric relationship where the hand cannot simultaneously block both the detection unit and camera unit.
2Ease of operation
If the detection unit is positioned to detect user state, then user interaction can be recognized, but the detection range is blocked by the user's hand covering the unit
Solution Approach 1:
The detection unit is repositioned to a corner of the housing, utilizing three-dimensional spatial arrangement to escape the blocking zone created by natural hand holding positions. This geometric relocation ensures the detection unit's field of view remains unobstructed while maintaining user state detection capability.
Solution Approach 2:
The patent employs asymmetric positioning of the detection unit in a corner rather than a symmetric or central position. This asymmetric layout creates an unbalanced spatial distribution that strategically places the detection unit in a location least likely to be blocked by the user's hand, optimizing both detection accuracy and operational ease.
3Manufacturing precision
If high-performance camera components are used, then image quality is improved, but the performance cannot be demonstrated due to unintentional blocking by hand
Solution Approach 1:
By repositioning the detection unit to a corner position, the patent creates a spatial configuration where the high-performance camera components can operate at full capability without being inadvertently blocked. This geometric solution ensures that the investment in high-quality camera components translates into actual performance benefits.

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.
