Base Member With Pliable Lips for Detachable Post Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching upwardly extending posts to surfaces result in non-detachable connections, leading to material waste and additional work when posts are damaged, as both the support and hollow members need replacement.
Innovation Solution
A base member with pliable lips formed by cuts in the connection profile, secured by bolts, allows detachable attachment of upwardly extending posts, distributing impact energy and facilitating easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the hollow component and support member are forced together to create a secure connection, then the connection strength is improved, but the ability to detach and replace components is lost
Solution Approach 1:
The connection is segmented into a reusable base member with connection profile and a replaceable upwardly extending post. The connection profile includes pliable lips that can be independently adjusted, allowing the post to be detached and replaced while keeping the base member intact.
Solution Approach 2:
The pliable lips provide a dynamic connection mechanism that can transition between clamped and released states. When the bolt is tightened, the pliable lips deform to clamp against the post; when loosened, they return to their original position, releasing the post for replacement.
2Strength
If both the support member and hollow member are replaced when damaged, then the connection strength is maintained, but material waste increases
Solution Approach 1:
The base member with connection profile is designed to be reusable and recovered after the upwardly extending post is replaced. Only the damaged post is discarded, while the intact base member is retained for reusing with a new post, significantly reducing material waste.
3Strength
If both the support member and hollow member are detached and replaced, then the connection is renewed, but additional work is required
Solution Approach 1:
The system is segmented so that only the upwardly extending post needs to be detached and replaced, while the base member remains in place. This reduces the replacement process from detaching two components to detaching only one, improving productivity.
Solution Approach 2:
The base member is pre-installed and the connection profile is prepared in advance with pliable lips and bolt holes. This preliminary setup allows for quick replacement of the post by simply loosening the bolt and removing the post, without needing to reposition or prepare the base member.
4Device complexity
If the bolt alone transfers impact energy, then the connection is simple, but the risk of bolt failure increases
Solution Approach 1:
The connection profile has different local qualities: rigid sections for structural integrity and pliable lips for impact absorption. The pliable lips are specifically designed to be more compliant, allowing them to deform and absorb impact energy locally, protecting the bolt from excessive forces.
Solution Approach 2:
The pliable lips act as a cushioning element positioned between the bolt and the external impact forces. They deform under impact, absorbing energy before it reaches the bolt, thereby protecting the bolt from failure in advance of any potential damage.
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
The solution provides a secure, detachable connection that reduces the risk of bolt failure and allows for quick replacement of damaged posts, promoting material reuse.
Implementation Method 1
By tightening the bolt, the pliable lips formed by the first cut and the second cut will be clamped against the upwardly extending post. This causes sufficient friction between the base member and the upwardly extending post, so that the base member and the upwardly extending post are firmly secured to each other.
Implementation Method 2
This is additionally beneficial because energy of a mechanical impact on the upwardly extending post is transferred via these pliable lips, and not only via the bolt, avoiding high tension on a single point and significantly reducing the risk on failure of the bolt.
