Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tube axial fans are used for cooling, then cooling function is provided, but airflow efficiency is insufficient and noise is high
Solution Approach 1:
The patent changes the fundamental operating parameters of the fan system by transitioning from axial flow to radial flow configuration. This parameter change enables the centrifugal fan to achieve higher airflow efficiency and lower noise levels while maintaining the required cooling function for the display assembly.
2Reliability
If tube axial fans are used for cooling, then cooling function is provided, but noise emission is high
Solution Approach 1:
The patent changes the fundamental operating parameters of the fan system by transitioning from axial flow to radial flow configuration. This parameter change enables the centrifugal fan to achieve higher airflow efficiency and lower noise levels while maintaining the required cooling function for the display assembly.
3Productivity
If centrifugal fans are used, then airflow efficiency is improved and noise is reduced, but device complexity increases
Solution Approach 1:
The patent merges the fan housing with the display assembly housing, integrating the cooling system into the existing structure. This consolidation reduces overall device complexity while maintaining the airflow efficiency benefits of centrifugal fan design.
4Reliability
If display assemblies are placed in sealed housings to protect from harsh conditions, then protection is improved, but thermal management becomes more difficult
Solution Approach 1:
The patent introduces a centrifugal fan as an intermediary device that actively manages heat removal from the sealed housing. The fan creates controlled airflow pathways that efficiently extract heat from internal components while maintaining the protective sealed environment, thus resolving the thermal management challenge.

AI summary
A display assembly with integrated electric vehicle charging equipment includes a first and second side assembly connected to a structural frame, each including an electronic display subassembly located behind a cover. The electric vehicle charging equipment is connected to the structural frame between said first and second side assemblies in an at least partially recessed manner. Open or closed loops of air may be provided for cooling the first and second side assemblies and the electric vehicle charging equipment, which may all be connected to a common power source.
