Material Handler Tower With Interior Fastener Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material handler towers lack effective protection for fastener heads from damage due to their external location, which can lead to shearing or damage from moving materials.
Innovation Solution
A tower design with an interior mounting system featuring a base plate with interior mount openings that receive fasteners, positioning their heads inside the housing for protection, and using high-strength steel for the housing and base plate to manage stress loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fasteners are mounted externally on the tower housing, then installation and access are simplified, but the fastener heads are vulnerable to damage from moving materials
Solution Approach 1:
The mounting system is nested within the tower housing structure. The base plate is positioned inside the housing, and mount openings are provided through the housing walls, allowing fasteners to be installed from the interior side. This nesting arrangement protects the fastener heads from external damage while maintaining installation accessibility.
Solution Approach 2:
The housing structure serves as an intermediary protective element between the fastener heads and the moving materials. By positioning the fastener heads inside the housing and using the housing walls as mounting surfaces, the system mediates the exposure to harmful factors while maintaining the mounting function.
2Strength
If high-strength steel is used for the housing and base plate, then the mounting system can withstand operational stress loads, but the weight of the tower increases
Solution Approach 1:
High-strength steel is applied locally only to the base plate and critical mounting areas where stress loads are concentrated, rather than throughout the entire tower structure. This localized application provides the necessary strength for the mounting system while minimizing the overall weight increase of the tower.
Solution Approach 2:
The mounting system utilizes composite construction combining high-strength steel base plate with the tower housing structure. This composite approach allows the critical mounting components to have the necessary strength properties while the overall structure can use lighter materials where full strength is not required.

AI summary
A tower for a material handler includes a housing surrounding an interior space. The tower has an interior mounting system including a base plate through which a plurality of interior mount openings pass. The interior mount openings are located at positions of the base plate that are interior of the housing. In some embodiments, the tower is part of a material handler that also includes two stabilizers located on opposite sides of the tower, a platform located above the tower, and a boom projecting away from the platform.
