Solution Overview
Problem
Current lighting pole installation methods are costly, time-consuming, and require skilled labor, and existing concrete structures are not suitable for areas with specific environmental constraints.
Innovation Solution
A foundation equipment comprising a threaded shank and a box-like body with a conical connection for easy assembly and grounding, allowing for quick and labor-efficient installation of lighting poles, with features like through holes for cable passage and a manhole design for electrical connections, and optional features for improved stability and environmental adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If concrete foundation structures are used for pole installation, then structural stability is achieved, but installation cost and time increase significantly
Solution Approach 1:
The foundation equipment is divided into separate modular components: a lower treaded shank for ground insertion and an upper box-like body for pole mounting. This segmentation allows pre-fabrication and rapid assembly, eliminating time-consuming on-site concrete pouring while maintaining structural integrity through the threaded connection between segments.
Solution Approach 2:
The foundation equipment is pre-assembled and pre-positioned before final pole installation. The lower shank is inserted into the ground in advance, and the upper body is prepared with alignment features, enabling rapid final assembly when the pole arrives, thus reducing overall installation time while ensuring proper positioning.
2Strength
If traditional concrete foundations are used, then structural strength is ensured, but skilled labor requirements increase
Solution Approach 1:
The foundation equipment incorporates self-aligning features through its conical connection geometry and positioning elements. The conical shape automatically guides the upper body into correct alignment with the lower shank during assembly, eliminating the need for skilled workers to perform complex alignment operations while ensuring proper structural positioning.
Solution Approach 2:
The invention replaces the complex mechanical process of concrete pouring, curing, and formwork removal with a simplified mechanical assembly system. The threaded connection and conical alignment mechanisms provide inherent positioning and securing functions that previously required skilled labor operations, making the installation process accessible to workers with basic training.
3Reliability
If concrete structures are used for pole installation, then stability is achieved, but environmental constraints are violated in sensitive areas
Solution Approach 1:
The lower shank features adjustable threading parameters and ground insertion depth that can be modified to suit different environmental conditions. The threaded connection allows for variable engagement depths and configurations, enabling the same foundation equipment to achieve stable installation in diverse environments including sensitive areas where concrete pouring is prohibited, thus providing both stability and environmental adaptability.
