Height Adjustable Platform Brake Assembly with Dual Torsion Springs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desks lack the ability to adjust height easily, making it difficult for users to alternate between standing and sitting, which is beneficial for health, and require significant effort to change the work surface height.
Innovation Solution
A height adjustable platform with a brake assembly and counterbalance mechanism that includes a lock rod and torsion springs, allowing the work surface to be securely positioned at various heights with reduced user effort, featuring a locked, unlocked, and safety configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the work surface height is fixed at a standard seated position, then the desk structure is simple and stable, but the user cannot alternate between standing and sitting which causes health issues
Solution Approach 1:
The patent implements a dynamic height adjustment mechanism where the brake assembly can selectively engage and disengage from the lock rod, allowing the work surface to transition between fixed and movable states. This enables the system to adapt between different height positions while maintaining structural stability when locked.
Solution Approach 2:
The height adjustment system is divided into separate functional components: the brake assembly with torsion springs for engagement control, the lock rod for positioning, and the work surface. This segmentation allows each component to perform its specific function independently, simplifying the overall mechanism while achieving height adjustability.
2Reliability
If a heavy-duty locking mechanism is used to securely hold the work surface at various heights, then the positioning stability is improved, but the user effort required to adjust the height increases
Solution Approach 1:
The torsion springs in the brake assembly act as counterbalancing elements that offset the weight of the work surface. When the brake assembly engages with the lock rod, the springs provide sufficient holding force to secure the position without requiring additional locking mechanisms, while still allowing easy release when needed.
Solution Approach 2:
The brake assembly is designed to automatically engage with the lock rod when the work surface reaches a desired height position. The torsion springs provide the necessary force for automatic engagement and disengagement, eliminating the need for manual intervention to secure or release the height adjustment.
3Reliability
If the brake assembly uses a single torsion spring for engagement, then the mechanism is simple, but the reliability of the locking mechanism is insufficient
Solution Approach 1:
The patent employs two torsion springs positioned at different locations within the brake assembly, each providing independent engagement force. This local distribution of locking function ensures that if one spring fails or is insufficient, the other maintains the locking reliability, while the overall structure remains relatively simple.
