Operation Button Marking for Fast Function Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices fail to provide clear visual cues for function allocation changes on operation buttons, making it difficult for users to recognize the functions assigned to these buttons.
Innovation Solution
The input device incorporates detachable mark members with fitting protrusions that attach to operation buttons, providing visual indicators for function recognition, and detachable operation buttons with unique shapes and protrusions for easy identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If function allocation of operation buttons is changed, then the device can adapt to different applications, but the functions become unrecognizable by appearance alone
Solution Approach 1:
The mark member is separated from the operation button body, allowing independent attachment and detachment. The mark member includes a fitting protrusion that fits into a fitting groove on the button, enabling users to attach different mark members to indicate different functions without changing the button itself.
Solution Approach 2:
The mark member features a top portion with marks (such as letters, numbers, or symbols) that provide visual indicators of the button's current function. Different mark members can have different colors or markings to represent different functions, making the function recognizable by appearance.
2Loss of information
If mark members are attached to operation buttons, then function recognition is improved, but the device structure becomes more complex
Solution Approach 1:
The mark member is designed as a separate component from the operation button, with a fitting protrusion that attaches to a fitting groove on the button. This segmentation allows the mark member to be independently manufactured, attached, and detached without affecting the button's core structure or functionality.
Solution Approach 2:
The fitting groove and protrusion design creates a universal attachment mechanism that can accommodate different mark members on the same button. The same fitting structure is used across multiple buttons, allowing standardized mark member attachment and simplifying the overall system design.

AI summary
Provided is an input device which enables a user to quickly recognize a function allocated to an operation button. A controller (2000) includes a main body (2100), a plurality of second operation buttons (2120, 3200) that are attached to the main body and that each include an upper surface portion allowed to be pushed downward, and mark members (2400, 3400) detachably attached to the plurality of second operation buttons. Each of the mark members includes a top portion (2401, 3401) indicating a mark on the basis of which the user recognizes a function allocated to the corresponding second operation button of the plurality of second operation buttons.
