Light Pole Foundation Stone Cable Routing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing light pole foundation stones complicate the replacement process of light poles due to the need to remove electrical connecting cables from lateral cable feed-through openings, often requiring complex excavation and risking damage to the cables.
Innovation Solution
A light pole foundation stone design where the light pole can be easily removed without disengaging the electrical connection cables from the cable entry opening, reducing the number of cable penetrations and allowing deeper burial of cables for better protection, with a simplified manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lateral cable feed-through openings are used in the foundation stone, then electrical connection cables can be routed to the light pole, but the replacement of the light pole becomes complex and requires extensive excavation work
Solution Approach 1:
The patent extracts the cable feed-through function from the foundation stone by using a separate cable conduit that passes through the ground independently of the foundation stone. This allows cables to be routed without creating lateral openings in the foundation stone, thereby simplifying light pole replacement while maintaining cable routing capability.
Solution Approach 2:
The patent separates the cable routing function from the foundation stone structure by introducing a distinct cable conduit component. This segmentation allows the foundation stone to focus on anchoring the light pole while the separate conduit handles cable passage, resolving the conflict between cable routing and replacement simplicity.
2Adaptability or versatility
If lateral cable feed-through openings are created in the foundation stone, then cables can enter the light pole, but the mechanical stability of the light pole is reduced
Solution Approach 1:
The cable feed-through function is extracted from the foundation stone and relocated to a separate conduit embedded in the ground. This eliminates lateral openings in the foundation stone, preserving its mechanical integrity and stability while still enabling cable entry to the light pole.
3Ease of manufacture
If cables are routed through lateral openings near the ground surface, then cable installation is simplified, but cables become vulnerable to external influences and theft
Solution Approach 1:
The patent nests the cable conduit within the ground, embedding it deep below the surface. This nested configuration protects cables from external influences and theft while maintaining a straightforward installation process, as the conduit is pre-installed in the ground before the light pole is mounted.
Solution Approach 2:
The cable conduit is installed in advance during ground preparation, before the light pole is mounted. This preliminary action allows cables to be routed through the pre-positioned conduit without requiring later excavation or complex installation work, thus maintaining ease of manufacture while enhancing cable protection.
4Adaptability or versatility
If multiple cable penetrations are created in the foundation stone, then all necessary cables can be routed, but the manufacturing complexity increases
Solution Approach 1:
The patent removes the cable routing function from the foundation stone manufacturing process entirely. By using a separate conduit installed in the ground, the foundation stone can be manufactured as a simple anchoring component without any cable penetrations, greatly simplifying manufacturing while maintaining cable routing flexibility through the independent conduit system.

AI summary
The lamp post foundation brick (1) comprises a receptacle (2) for locally receiving a lamp post. The receptacle has an opening (3) for insertion of the lamp post into the receptacle. The opening is arranged in the area of a head end (4) of the lamp post foundation brick. A cable passage opening (5) is centrally arranged at the end of the receptacle opposite to the opening. The cable passage opening is designed as a through-hole having an oval cross-section. The cross-section of the receptacle in the area of the cable passage opening conically tapers in the direction of cable passage opening. An independent claim is included for a lamp post arrangement with a lamp post foundation brick and an electrical connection cable.
