Adjustable Rod Guide for Openable Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rod guides for openable elements like doors and hatches are static, leading to tension in the rods and potential brittleness over time, especially in environments requiring robust materials and constructions.
Innovation Solution
A rod guide comprising a first part with a recess extending from its bottom side and a second part that is movable relative to the first part, allowing for height adjustment of the rod guide to alleviate tension in the rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a static rod guide is used, then the structure is simple and robust, but tension is induced in the rod which reduces reliability and causes brittleness over time
Solution Approach 1:
The rod guide transitions from a static structure to a dynamic adjustable structure. The second part can move relative to the first part along the recess, allowing the rod guide to adapt its position and eliminate tension in the rod during operation, thereby improving reliability without excessive complexity
Solution Approach 2:
The rod guide is divided into two separate parts: a first part that provides structural support and a second part that contains the rod receptacle and can move independently. This segmentation allows the movable portion to adjust while the fixed portion maintains structural integrity
2Ease of operation
If a static rod guide is used, then manufacturing is simple, but the rod guide cannot be adjusted to precise positions which reduces ease of operation
Solution Approach 1:
The adjustable design allows the rod guide to be positioned optimally during installation and operation, ensuring smooth rod movement without binding or tension. The height adjusting element enables precise positioning while maintaining operational simplicity
Solution Approach 2:
The rod guide includes self-adjustment capabilities through the movable second part and height adjusting element, allowing it to automatically accommodate rod movement requirements without complex external adjustment mechanisms
3Duration of action of stationary object
If a static rod guide is used, then the device is robust and simple, but it induces tension in the rod which reduces the lifespan of the openable element
Solution Approach 1:
The movable second part allows the rod guide to dynamically adjust its position along the recess to eliminate tension in the rod during opening/closing operations. This reduces stress on the rod and extends the lifespan of the openable element
Solution Approach 2:
The height adjusting element allows for preliminary adjustment of the rod guide position during installation, ensuring optimal positioning before operation begins. This prevents tension from developing during use and extends component life
