Multi-sided Display Sign Apparatus with Rotating Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-electronic display signs with triangular panels are limited to displaying only one scene at a time and can only show three distinct scenes, which restricts their versatility and effectiveness in displaying multiple pictorial or informational content.
Innovation Solution
A multi-sided display sign apparatus featuring a stationary frame with rotating elongated display sign elements, a movable frame, and electric drive systems that allow for lateral movement and incremental rotation of panels to display multiple scenes simultaneously, enabling the display of four distinct scenes and operation in outdoor environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If triangular panels are used in a side-by-side arrangement, then the display sign can show multiple scenes, but it is limited to only three distinct scenes and one scene at a time
Solution Approach 1:
The display sign is divided into multiple independent elongated panels, each capable of independent rotation. Each panel can be segmented into multiple sides with different scenes, allowing the system to display more than three distinct scenes by combining different panels and sides.
Solution Approach 2:
The patent transitions from a two-dimensional side-by-side triangular panel arrangement to a three-dimensional configuration where elongated panels can rotate about their longitudinal axes. This adds a rotational dimension, enabling multiple scenes to be displayed on different sides of the same panel, thereby increasing the total number of distinct scenes beyond the traditional limit.
2Productivity
If triangular panels rotate in unison, then the display is simple to operate, but only one scene can be displayed at any given time
Solution Approach 1:
The patent introduces dynamic independent rotation capability to each elongated panel, allowing individual panels to rotate at different speeds or independently of each other. This dynamic control enables multiple scenes to be displayed simultaneously on different panels or sides, increasing scene display capacity while maintaining operational simplicity through coordinated control mechanisms.
3Adaptability or versatility
If elongated display sign elements are mounted for rotation, then multiple scenes can be displayed, but the device complexity increases with mounting means and drive means
Solution Approach 1:
The mounting means and drive means are designed to be universal and reusable across multiple elongated panels. The same mounting mechanism can accommodate different panel configurations, and the drive system can control multiple panels independently or simultaneously, reducing the overall complexity compared to having separate mechanisms for each panel.

AI summary
A display sign apparatus includes a stationary frame and a movable frame mounted therein for reciprocal lateral movement. One drive system is provided for moving the movable frame. Each of the stationary and movable frames has a plurality of elongated display sign elements mounted in a spaced relationship. Another drive system is provided for rotating each element about its longitudinal axis. The elongated display sign elements are movable between a first position wherein the elements are interposed with a side-by-side arrangement and a second position wherein the elements in the movable frame are laterally spaced from the elements mounted on the stationary frame.
