Multi-Weight Display Stand Riser With Selective Boost Springs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current height adjustable stands for displays are typically designed for specific weight classes, leading to issues where heavier displays sag or lighter displays tilt excessively when using the wrong stand, resulting in increased non-recurring engineering and logistical costs due to the need for multiple stand part numbers to accommodate different weight classes.
Innovation Solution
A height adjustable stand with a lift assembly featuring a primary spring and one or more boost springs that provide opposing lift forces, and a pivot assembly with primary and boost springs for tilt support, allowing for adjustable spring forces to match the weight and tilt requirements of multiple display weight classes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a HAS stand is designed for a specific weight class, then it can properly support displays of that weight class, but it cannot properly support displays of other weight classes
Solution Approach 1:
The spring system is segmented into multiple independent springs (first spring, second spring, third spring, fourth spring) that can be selectively engaged. Each spring is configured to provide appropriate lift force for specific display weight classes, allowing the stand to be adapted to different weights by engaging the appropriate spring combination.
Solution Approach 2:
The HAS stand is designed with universal adaptability to support multiple display weight classes (first, second, and third weight classes) using a single stand structure. The multi-spring configuration allows the same stand to properly support lighter displays, medium-weight displays, and heavier displays by selectively engaging different springs.
2Reliability
If multiple stand part numbers are provided to support different display weight classes, then each weight class can be properly supported, but non-recurring engineering and logistical costs increase
Solution Approach 1:
Multiple spring mechanisms that would traditionally require separate stand models are merged into a single integrated stand structure. The stand includes all necessary springs (first, second, third, and fourth springs) within one design, allowing it to accommodate multiple display weight classes without requiring multiple different stand part numbers.
Solution Approach 2:
The stand employs dynamic spring engagement where the lift assembly can selectively activate different springs based on the display weight class. This dynamic configuration allows a single stand to adapt its mechanical properties to match different load requirements, eliminating the need for static, weight-specific stand models.
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
Enables the support of multiple weight classes of displays with reduced non-recurring engineering and logistical costs by automatically or manually adjusting spring forces to maintain stable display positioning, reducing sagging and tilting issues.
Implementation Method 1
a lift assembly that includes a primary spring and one or more boost springs that provide opposing lift forces matched to the weight of the display
Implementation Method 2
a pivot assembly that includes a primary spring and one or more boost springs that provide opposing pivot forces matched to the weight of the display

AI summary
Described are display riser, height adjustable stand (HAS) and a method to support lift and tilt of multiple weight classes of displays. A lift includes a primary spring and one or more boost springs. The primary spring is used for all displays supported by the HAS and the one or more boost springs are engaged when supporting displays requiring additional lift support. A pivot assembly includes a primary torsion spring and one or more boost torsion springs. The primary spring torsion is used for all displays supported by the HAS and the one or more boost torsion springs are engaged when supporting displays requiring additional tilt support.
