Box Enclosure Hoist Traverse Path for Spring Torque Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attic stair systems require significant force to change the spring attachment position, necessitating detachment and reattachment, which is cumbersome and inefficient.
Innovation Solution
A continuous hoist assembly traverse path for the spring end allows for automatic adjustment of the spring attachment position without detachment, using a fixed and articulated structural elements with a spring connected between them, enabling easy and controlled torque adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the spring attachment position is changed by detaching and reattaching the spring, then the spring torque can be adjusted, but significant force is required and the process is cumbersome
Solution Approach 1:
A traverse path mechanism is introduced as an intermediary between the spring and the support structures. This traverse path guides the spring end through a controlled movement path, allowing the spring to automatically shift between attachment positions without requiring manual detachment and reattachment. The traverse path effectively mediates the transition, converting a difficult manual operation into an automated guided process.
Solution Approach 2:
The system transitions from a static attachment configuration to a dynamic one where the spring attachment position can change automatically. The traverse path enables the spring end to move dynamically between different attachment positions on the support, allowing the system to adapt its configuration based on operational requirements without manual intervention.
2Adaptability or versatility
If multiple attachment openings are provided on supports, then spring torque adjustment is possible, but the process requires detaching and reattaching the spring which is time-consuming
Solution Approach 1:
The traverse path acts as an intermediary mechanism that eliminates the need for manual detachment and reattachment. Instead of directly moving the spring between attachment points on supports, the traverse path guides the spring end through a controlled path that automatically positions it at the desired attachment location, significantly reducing adjustment time.
Solution Approach 2:
The traverse path is pre-configured with the complete movement path between all attachment positions. This preliminary preparation allows the spring to automatically follow the predetermined path when changing attachment positions, eliminating the need for manual positioning and reducing adjustment time to merely activating the traversal mechanism.
3Adaptability or versatility
If the spring is detached and reattached at different positions, then torque adjustment is achieved, but the process requires significant manual force
Solution Approach 1:
The traverse path mechanism serves as an intermediary that takes over the force-intensive task of moving the spring between attachment positions. Instead of requiring manual force to detach and reattach the spring, the traverse path uses its guided movement mechanism to automatically reposition the spring end, dramatically reducing the manual force required.
Solution Approach 2:
The system enables self-service repositioning of the spring through the traverse path mechanism. Once activated, the mechanism automatically guides the spring end along the predetermined path to the target attachment position without requiring continuous manual force or intervention, allowing the system to service itself during adjustment operations.
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
Facilitates convenient and controlled adjustment of spring torque by allowing the spring end to skip between attachment positions along a guided path, reducing the need for manual detachment and reattachment, thus improving ease of use and adaptability to changing conditions.
Implementation Method 1
