Solution Overview
Problem
Existing modular lamp posts face challenges in managing cabling complexity and providing adequate protection for functional units, particularly with camera pole modules, leading to difficulties in maintaining ingress protection and user-friendly installation.
Innovation Solution
A modular post design featuring a functional pole module with a housing comprising a lower, middle, and upper section, equipped with a power and data interface for connecting and powering other modules, allowing for wireless communication and reduced cabling density, along with rotational flexibility and sealed compartments for improved protection and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pole modules are connected using traditional cabling methods, then functional connectivity is achieved, but cabling complexity and installation difficulty increase
Solution Approach 1:
The patent combines power transmission and data communication into a single integrated cable connection. The power and data interface integrates both functions, allowing simultaneous power supply and data exchange through one connection point, thereby reducing cabling complexity and improving installation ease.
Solution Approach 2:
The power and data interface serves multiple functions: it provides power to functional units, transmits data between modules, and enables wireless communication connectivity. This multi-functional design reduces the number of separate cables needed and simplifies the overall cabling infrastructure.
2Ease of repair
If functional units are exposed to the environment for easy access, then maintenance becomes easier, but protection against water ingress deteriorates
Solution Approach 1:
The housing is divided into distinct sections (first section, second section, third section) that can be independently accessed. Each section contains specific functional units and can be opened or removed separately, allowing maintenance personnel to access specific components without exposing the entire functional unit to the environment, thus maintaining protection while enabling easy maintenance.
Solution Approach 2:
Functional units are nested within sealed compartments formed by the housing sections. The functional units are protected within these compartments while still allowing controlled access through opening mechanisms, enabling maintenance without compromising the overall protection against water ingress.
3Object-affected harmful factors
If rigid sealing is implemented to protect functional units, then water ingress protection improves, but installation flexibility and positioning adaptability worsen
Solution Approach 1:
The housing incorporates dynamic opening mechanisms that allow the sealed compartments to be opened and closed. This dynamic design enables the functional units to be accessed for maintenance while maintaining the sealed protection during operation and installation, thus reconciling the need for both protection and flexibility.
Solution Approach 2:
The sealing and opening mechanisms are applied locally to specific sections of the housing rather than the entire structure. This allows different parts of the functional unit to have different levels of protection and accessibility, enabling positioning flexibility where needed while maintaining protection where required.
