Lens Cap Assembly Display for Lens Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identifying and distinguishing between different lenses stored together is confusing and time-consuming due to the lack of clear information on their characteristics when detached from a camera body.
Innovation Solution
Integration of a display within lens caps that communicates with the lenses via electrical contacts to display lens information, such as focal length and brand, allowing users to quickly identify each lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lens caps are used to protect detached lenses, then lens protection is improved, but lens identification becomes difficult and time-consuming
Solution Approach 1:
The patent introduces an intermediary device (display unit integrated into the lens cap) that mediates between the lens information storage (memory) and the user. This display unit visually presents lens characteristics such as focal length and aperture, serving as a mediator that translates stored data into easily recognizable visual information, thereby solving the identification problem while maintaining protection functionality.
Solution Approach 2:
The patent creates a visual copy of lens information on the lens cap display. Instead of requiring users to physically examine or remember lens specifications, the system creates a digital copy of relevant lens characteristics (focal length, aperture, brand) and displays them on the cap, enabling quick identification without handling the lens itself.
2Loss of information
If lens information is stored in lens memory, then lens characteristics are preserved, but quick identification of detached lenses remains difficult
Solution Approach 1:
The patent replaces the mechanical/manual process of identifying lenses (physically examining lenses, comparing markings, or consulting separate documentation) with an electronic information system. The microcontroller reads from lens memory and automatically displays relevant characteristics on the integrated display unit, substituting manual identification operations with automated electronic information retrieval and presentation.
Solution Approach 2:
The lens cap system provides self-service by automatically retrieving and displaying lens information without requiring external assistance or manual intervention. When the cap is attached to a lens, the system autonomously powers up, reads the lens memory, and presents the information on the display, making the identification process self-contained and user-friendly.
3Ease of operation
If a display is integrated into lens caps with electrical communication, then lens identification is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality in the lens cap assembly, combining protection, information storage, wireless communication, and display functions into a single device. The lens cap serves not only as a protective cover but also as an information terminal that can display lens characteristics, store data, and potentially communicate wirelessly, thereby justifying the increased complexity through enhanced functionality.
Solution Approach 2:
The patent merges previously separate functions (lens protection cap, information storage memory, display unit, and communication interface) into a single integrated assembly. By combining these elements into one unified device attached to the lens, the system reduces the need for multiple separate components and manual processes, making the overall system more cohesive despite the added complexity of individual elements.

AI summary
Disclosed are lens cap assemblies wherein a removable lens cap may include a lens cap body that is configured to be removably attached to an end of a lens. The lens cap can further include a cap communication interface configured to receive lens information from a lens communication interface while the lens cap is in an attached position. The lens cap can include a display to allow for the displaying of lens characteristics and information.
