Compact Display Device Using Slide Mechanism for Pushbutton Switches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for pushbutton switches have complex constructions leading to large volumes, making them non-compact and cumbersome.
Innovation Solution
A display device with a movable display element and a slide mechanism featuring a contact bevel and guide slots, allowing the display element to rotate about an axis, optimizing space usage and enabling a compact design by deflecting the actuating element's movement transversely, using spherical or disc-shaped display elements that enclose the axis of rotation, and allowing modular combinations of symbols or colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotary member with multiple display sections is used to display different positions, then the display functionality is achieved, but the construction becomes complex and the volume increases
Solution Approach 1:
The display element is divided into multiple display sections (first display section and second display section) that can be selectively positioned behind the window. Each section contains different switching position information, allowing the display to show different states without requiring a complex rotary mechanism with all sections permanently attached.
Solution Approach 2:
The invention transitions from a traditional rotary member that rotates to bring different sections into view to a slide mechanism that moves the display element linearly. The contact bevel converts the axial movement of the actuating element into transverse movement of the display element, achieving position indication through a different dimensional approach that reduces complexity.

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in a compact and simple construction of the pushbutton switch, enabling efficient use of space and allowing for various symbol or color combinations, while maintaining the functionality of displaying different sections behind the window based on the actuating element's position.
Implementation Method 1
The spring is arranged to act on the actuating element in order to restore the actuating element into the first position from the second position

AI summary
The device has a movable indicator unit (4) including a slider (5) with a chamfered edge (52) that lies on a portion of a housing (3). The chamfered edge causes a displacement of the slider from an initial position to an end position with respect to a window (21) of an actuating unit (2) during a movement of the actuating unit from one position to another position, where the movement is exerted with respect to the housing. The displacement causes a rotation of the indicator unit about a rotational axis (6) that runs through the indicator unit.
