Solution Overview
Problem
Existing display systems that raise and lower above a table or working surface using electric motors are prone to failure, require a power supply, and occupy space under the surface, making them unreliable and inefficient.
Innovation Solution
A pop-up display apparatus utilizing constant force springs and tracks to drive and guide the display assembly from a lowered to a raised position, with pins and tracks guiding movement and dampers slowing the display's ascent, eliminating the need for electric motors and power supplies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electric motors are used to move the display up and down, then the display can be raised and lowered, but the device requires a power supply and occupies space under the table
Solution Approach 1:
The patent replaces the electric motor system with a purely mechanical constant force spring mechanism. The spring provides continuous mechanical force to raise the display without requiring electrical power, eliminating motors, power supplies, and associated control electronics while maintaining the display movement capability
Solution Approach 2:
The constant force spring is pre-loaded and automatically provides the force needed to raise the display when released. The system serves itself by using the spring's stored mechanical energy rather than requiring external power sources or control systems
2Ease of operation
If electric motors are used to move the display, then the display can be raised and lowered, but the motors are prone to failure and leave the display stuck
Solution Approach 1:
The patent replaces the electric motor system with a purely mechanical constant force spring mechanism. The spring provides continuous mechanical force to raise the display without requiring electrical power, eliminating motors, power supplies, and associated control electronics while maintaining the display movement capability
Solution Approach 2:
The constant force spring is pre-loaded with sufficient force to reliably raise the display assembly. This pre-loaded mechanical energy acts as a backup that ensures the display can be raised even if other components fail, reducing the overall system's vulnerability to failures
3Adaptability or versatility
If the display is lowered below the table surface, then it can be hidden when not in use, but space is required under the table for the mechanism
Solution Approach 1:
The display assembly is nested within the housing structure when lowered. The constant force spring mechanism is integrated into the housing, allowing the entire system to be compact when the display is in its stored position below the table surface
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 provides a reliable, space-efficient, and motor-free mechanism for raising and lowering displays, ensuring consistent movement and reducing the risk of mechanical failure, while allowing for easy operation and storage below the surface.
Implementation Method 1
at least one constant force spring having at one end a coiled part that is rotatably coupled to the display assembly, and an opposing end fastened to a fixed mounting location, and an uncoiled part extending between the coiled part and the opposing end; the at least one constant force spring being configured to drive the display assembly from a lowered position to a raised position
