Foundation Member Cable Theft Deterrent Clamp Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing theft of underground electrical cables and wires from conduits, particularly from screw foundations supporting light poles, remains a significant issue despite existing deterrent devices, as they can be damaged or bypassed, leading to financial losses for utility companies.
Innovation Solution
A foundation member with a clamp assembly that securely clamps underground electrical cables, positioning the clamp assembly between the foundation member and the electrical device, making it inaccessible once the device is mounted, thereby preventing unauthorized removal of the cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a clamp assembly is made accessible for installation, then ease of operation is improved, but security against theft deteriorates
Solution Approach 1:
The clamp assembly is pre-installed on the foundation member before the electrical device is mounted. This preliminary action ensures the clamp is in position to secure the cable before any theft can occur, while still allowing easy installation during the initial setup process.
Solution Approach 2:
The clamp assembly is positioned in a location that becomes inaccessible after the electrical device is mounted. By utilizing the spatial relationship between the foundation member, electrical device, and clamp, the system transitions from an accessible state during installation to an inaccessible state during operation, effectively preventing theft while maintaining ease of installation.
2Object-affected harmful factors
If access doors are made more secure, then security against theft is improved, but ease of operation deteriorates
Solution Approach 1:
The clamp assembly is extracted from the interior of the electrical device and positioned on the exterior foundation member. This separation allows the access door to remain simple and easily operable for making connections, while the clamp assembly provides theft deterrence independently on the foundation member.
Solution Approach 2:
The clamp assembly acts as an intermediary security measure between the foundation member and the electrical device. It provides theft protection without requiring modifications to the access door or the interior connection process, maintaining ease of operation while improving security.
3Object-affected harmful factors
If obstructive elements are placed along the cable, then theft prevention is improved, but device complexity increases
Solution Approach 1:
The clamp assembly merges the security function with the existing foundation member structure. Instead of adding multiple separate obstructive elements along the cable, the clamp is integrated into the foundation member, providing effective theft prevention with a single unified component.
Solution Approach 2:
The clamp assembly serves multiple functions: it secures the cable to prevent theft, provides structural support, and integrates with the foundation member. This multi-functionality reduces the need for additional separate components, thereby reducing overall device complexity while maintaining effective theft prevention.

AI summary
A foundation base member is provided for supporting an above ground electrical device such as a light pole and for supplying electrical wiring to the electrical device. The foundation base includes a body for inserting into the ground and has an axial passage for carrying the underground electrical wires to the electrical device. A base member is coupled to the top end of the foundation body and has a passageway aligned with the axial passage of the foundation body for receiving the electrical wires. The base member is adapted for coupling to and supporting the electrical device. A clamping device is received within a recess of the base member for fixing the position of the clamping device with respect to the foundation base. In one embodiment, the clamping device is captured between the foundation base and the electrical device. The wires are clamped in position by the clamping device to prevent unauthorized removal of the wiring.
