Lens Operation Apparatus Asymmetry for Left-Hand Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lens operation apparatuses are not designed for left-handed use, leading to inverted and difficult-to-read information and a risk of erroneous operation due to asymmetrically arranged switches and shared surfaces for auto-focusing and cross keys.
Innovation Solution
An operation apparatus with a rotatable operation member, a holder, and a display that ensures information is oriented towards the operation member, allowing easy reading and reducing the risk of accidental switch activation, featuring a convex portion with the display and cross key on an upper surface and switches on side surfaces, and a protection cover for easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lens operation apparatus is attached to the left-hand side, then it can be operated with the left hand, but information such as letters and LED lighting position cannot be read easily because orientations are inverted and turned upside down
Solution Approach 1:
The patent applies asymmetry by providing different attachment configurations for right-hand and left-hand operation. The housing includes a right-hand attachment portion and a left-hand attachment portion with different orientations, allowing the display and switches to be properly oriented regardless of which hand is used for operation.
Solution Approach 2:
The patent implements dynamics by making the attachment configuration adaptable to different usage scenarios. The lens operation apparatus can be dynamically attached to either the right-hand side or left-hand side of the lens apparatus, with the display and control elements automatically oriented correctly for each configuration.
2Ease of operation
If the lens operation apparatus is attached to the left-hand side, then it can be operated with the left hand, but switches are asymmetrically arrayed causing erroneous operation
Solution Approach 1:
The patent uses asymmetry to provide different switch arrangements for right-hand and left-hand attachment configurations. When attached to the left-hand side, the switches are arranged in a configuration suitable for left-hand operation, preventing erroneous operation while maintaining reliability.
Solution Approach 2:
The switch arrangement dynamically adapts to the attachment configuration. Whether the apparatus is attached to the right-hand side or left-hand side, the switches are positioned and oriented to match the operational hand, ensuring correct and reliable operation in both scenarios.
3Device complexity
If both the cross key and the switch for enabling auto-focusing are arranged on the same curvilinear surface, then the apparatus can be compactly designed, but there is a risk that the photographer can unintentionally touch the switch to cause erroneous operation
Solution Approach 1:
The patent applies segmentation by spatially separating the cross key and the auto-focusing switch onto different surfaces of the housing. This segmentation prevents unintentional activation of the switch while maintaining a compact overall design, as each element is positioned on an appropriate surface for its function.
Solution Approach 2:
The patent uses dimensional separation by placing the cross key and switch on different spatial dimensions (different surfaces of the housing). This dimensional arrangement maintains compactness while preventing erroneous operation through physical separation of the control elements.

AI summary
An operation apparatus for remotely operating a lens apparatus includes an operation member that rotates, a holder that holds the operation member, and a display supported by the holder, wherein the display displays information where an upward orientation of the displayed information is towards the operation member.
