Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If solar photovoltaic board is used to collect solar energy, then solar energy conversion to electric energy is achieved, but only lighting part of solar is used and major heat energy is not applied
Solution Approach 1:
The patent combines solar photovoltaic energy conversion with solar thermal energy collection by integrating a heat-absorbing vacuum tube alongside the photovoltaic board. The vacuum tube captures solar thermal energy to heat air inside the lamppost, which then drives a vane wheel generator to produce additional electricity, thereby utilizing both the lighting and heat portions of solar energy.
Solution Approach 2:
The lamppost structure is designed to serve multiple functions: it houses the LED lighting system, incorporates solar photovoltaic boards for electricity generation, integrates a heat-absorbing vacuum tube for thermal energy collection, and includes a vane wheel generator for kinetic energy conversion. This multi-functional design maximizes energy utilization from various sources.
2Reliability
If green energy sources are used in street lighting facilities, then environmental benefits are achieved, but the generated power is insufficient to meet full requirements
Solution Approach 1:
The patent merges three green energy generation systems: solar photovoltaic, solar thermal, and kinetic energy from vehicle traffic. By combining these multiple renewable sources, the system achieves sufficient power generation to meet the lighting requirements while maintaining environmental benefits and reducing reliance on traditional electricity.
Solution Approach 2:
The street lamp system generates its own electricity through multiple green energy sources integrated into its structure. The solar photovoltaic boards, heat-absorbing vacuum tube with vane wheel generator, and connection to road surface pressure devices enable the lamp to be self-sufficient in power generation, eliminating the need for external traditional power supply.
3Power
If heat-absorbing power generation vacuum tube is installed in lamppost, then thermal energy conversion is achieved, but system complexity increases
Solution Approach 1:
The lamppost is designed as a multi-functional integrated structure that combines lighting, solar photovoltaic energy collection, solar thermal energy collection, and kinetic energy conversion. By making the lamppost itself serve multiple functions, the patent avoids the need for separate standalone structures for each energy generation system, thereby managing complexity while maximizing power generation.
Solution Approach 2:
The heat-absorbing vacuum tube is nested within the lamppost structure, and the vane wheel generator is positioned inside the lamppost mouth. This nested arrangement allows multiple energy generation components to be compactly integrated within the existing lamppost framework, reducing overall system complexity and space requirements.
4Duration of action of stationary object
If multiple power generation systems are integrated, then energy supply sustainability is improved, but control and coordination difficulty increases
Solution Approach 1:
The patent incorporates a central controller that receives feedback from multiple sensors monitoring the operational status of different power generation systems. Based on this feedback, the controller automatically adjusts and coordinates the operation of solar photovoltaic, solar thermal, and kinetic energy systems to ensure continuous and sustainable power supply, simplifying the control of multiple integrated systems.
Solution Approach 2:
The central controller serves as a universal coordination device that manages all power generation and power storage components within the system. By creating a single multi-functional control unit, the patent simplifies the coordination complexity that would otherwise arise from managing multiple separate control systems for each energy generation source.
