Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building partition screens, such as roof window awnings, experience uncontrolled movement of the screening material beam due to wind and gravity, leading to detachment from couplers.
Innovation Solution
A building partition screen coupling unit with a beam and beam coupler system that includes control means, such as sprung shelves, magnets, or labyrinth-shaped traverse paths, to maintain the beam's position and prevent uncontrolled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the screening material beam is attached to beam couplers using simple hooks, then the device complexity is reduced and ease of manufacture is improved, but the beam becomes detached in windy conditions due to uncontrolled movement
Solution Approach 1:
The coupling unit incorporates a dynamic control means that allows the beam to move freely during installation and operation, but automatically stabilizes and holds the beam in position when wind loads or gravitational forces attempt to displace it. This dynamic response resolves the contradiction by providing both ease of operation and reliable attachment stability without requiring complex permanent fixation structures.
Solution Approach 2:
The control means within the coupling unit automatically detects and responds to forces attempting to move the beam, such as wind pressure or gravity, and self-adjusts to maintain proper beam positioning. This self-regulating mechanism eliminates the need for complex external control systems while ensuring reliable attachment under various operating conditions.
2Stability of the object's composition
If control means such as sprung shelves or magnets are added to the beam coupler, then the beam position stability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The control means utilizes changes in physical parameters such as spring deflection, magnetic field strength, or friction coefficients to achieve beam position stability. By adjusting these parameters within standard manufacturing tolerances, the system achieves reliable beam holding without requiring precision-engineered complex components, thus maintaining ease of manufacture while improving stability.
3Reliability
If the beam traverse path is shaped to prevent uncontrolled decoupling, then the reliability of beam attachment is improved, but the ease of operation deteriorates
Solution Approach 1:
The beam traverse path employs asymmetric geometry where the engagement direction (installation) follows a guided path that naturally prevents uncontrolled decoupling, while the disengagement direction (removal) allows for controlled release when force is applied in the opposite direction. This asymmetric design resolves the contradiction by providing both reliable attachment during normal operation and ease of removal when needed.
