Pole-Mounted Key Housing With Guarded U-Bolt Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for lockable containers do not securely attach them to poles or curved surfaces and fail to restrict access to the fasteners that secure the container, leaving them vulnerable to unauthorized removal.
Innovation Solution
A pole mount device using a U-bolt with a housing and guard plate that secures the container to a pole, where the U-bolt passes around the pole, and the guard plate covers the fasteners, limiting access to the nuts for securing the container, thereby enhancing security by making it difficult to remove the container from the pole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a container is mounted to a pole using conventional fasteners, then the container can be securely attached to the curved surface, but the fasteners remain accessible and vulnerable to unauthorized removal
Solution Approach 1:
The guard plate is nested within the housing structure, creating a protective enclosure around the fasteners. The housing contains the U-bolt and nuts, while the guard plate further encloses these components, forming nested protective layers that prevent unauthorized access while maintaining secure attachment
2Object-affected harmful factors
If the fasteners are completely enclosed to prevent access, then security is improved, but the ability to tighten or loosen the fasteners for installation and maintenance is compromised
Solution Approach 1:
The guard plate incorporates localized access features such as keyholes or restricted openings at specific locations. These local quality modifications allow authorized access for fastener operations while maintaining overall enclosure for security. The access points are strategically positioned to enable tightening and loosening operations without compromising the protective enclosure
3Adaptability or versatility
If a U-bolt is used to secure the housing to the pole, then the mounting system can accommodate curved surfaces effectively, but the structure becomes more complex compared to flat surface mounting
Solution Approach 1:
The U-bolt design serves multiple functions: it wraps around the curved pole surface for secure attachment, provides attachment points for the housing, and integrates with the guard plate structure. This multi-functional element reduces overall system complexity despite the curved surface requirement, as a single component accomplishes what would otherwise require multiple specialized parts

AI summary
The mounting system and device secures a container, such as a lockable container to a pole. A housing restricts access to the fasteners and other attachments that secure the container to the pole. A unitary fastener, such as a U-bolt, secures the housing to the pole. The two ends of the unitary fastener enter a first section of a rear wall and a second section of the rear wall to attach to the housing at an interior attachment surface. A curvature in the rear wall separates the first section and the second section of the rear wall. The curvature of the rear wall contacts the pole. The housing, the guard plate, and the container cover the fasteners to reduce access to the fasteners.
