Worm-Driven Sliding Block Structure for Stable Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving blocks for medical equipment and sofa seats lack sufficient connection strength and stability, leading to inaccurate position adjustments during up and down movements.
Innovation Solution
A driving block with a connection part and sliding part, featuring a connection column with a through-hole for worm insertion, a connection frame for sliding on a bracket, reinforced ribs between parts, a threaded structure for secure connections, and a lever for controlling positions and routes, made of polyformaldehyde (POM) for enhanced strength and resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the connection structure of the driving block is simplified, then the device complexity is reduced, but the connection strength and stability deteriorate
Solution Approach 1:
The driving block is divided into distinct functional segments: a connection part for mounting external devices and a sliding part for engaging with the sliding bracket. This segmentation allows each part to be optimized independently for its specific function while maintaining overall structural integrity through the reinforced connection area with ribs.
Solution Approach 2:
The driving block is made from polyformaldehyde (POM) material, which provides a composite of strength, durability, and resistance to wear and corrosion. This material choice enhances connection strength and stability without requiring overly complex structural designs.
2Ease of manufacture
If the connection structure is simplified, then the ease of manufacture is improved, but the connection stability deteriorates

The driving block is divided into distinct functional segments: a connection part for mounting external devices and a sliding part for engaging with the sliding bracket. This segmentation allows each part to be optimized independently for its specific function while maintaining overall structural integrity through the reinforced connection area with ribs.

3Strength
If the connection area is reinforced with ribs, then the connection strength is improved, but the device complexity increases
Solution Approach 1:
Ribs are added specifically in the connection area where strength is most needed, rather than uniformly throughout the entire driving block. This localized reinforcement provides enhanced connection strength at the critical interface between the connection part and sliding part, while minimizing the increase in overall structural complexity and material usage.
