Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for suspending objects on walls lack vertical and horizontal adjustability and reliability, often sagging under load or slipping due to asymmetrical surface loads and inadequate spring forces.
Innovation Solution
A fastening device featuring a sliding element with spring arms and a blocking element that restricts deformation, allowing for adjustable and secure positioning by engaging with a guide channel, preventing slipping and ensuring reliable engagement and disengagement without deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spring arms are used to allow displacement of the carrying element, then vertical adjustability is improved, but the spring arms may slip out of the toothing under asymmetrical load
Solution Approach 1:
A blocking element is introduced as an intermediary component between the spring arms and the guide channel toothing. This blocking element positively engages with the toothing to prevent the spring arms from slipping out, while allowing the spring arms to maintain their displacement function for vertical adjustment.
Solution Approach 2:
The fastening device is segmented into distinct functional components: spring arms for displacement, blocking element for engagement prevention, and guide channel for guidance. This segmentation allows each component to specialize in its function, with the blocking element specifically addressing the slipping problem without compromising the spring arms' adjustability function.
2Reliability
If high spring forces are applied to prevent slipping, then engagement reliability is improved, but the force required to displace the carrying element increases
Solution Approach 1:
The blocking element serves as a mediator that takes over the load-bearing engagement function from the spring arms. This allows the spring arms to use lower spring forces for displacement while the blocking element provides the necessary engagement reliability through positive toothing engagement.
3Stability of the object's composition
If the frame is made rigid to prevent sagging, then structural stability is improved, but the engagement elements cannot tilt to engage reliably in the toothing
Solution Approach 1:
The blocking element acts as an intermediary that ensures reliable engagement with the guide channel toothing regardless of frame stability. By providing positive engagement through the blocking element, the system achieves engagement reliability even when the frame sags slightly under load.
4Reliability
If a blocking element is introduced to prevent slipping, then engagement reliability is improved, but device complexity increases
Solution Approach 1:
The blocking element is merged with the carrying element in some embodiments, reducing the number of separate components. This integration approach maintains the slipping prevention function while minimizing the increase in device complexity.
