Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If heat sinks and fans are used to cool electronics, then cooling capability is improved, but heat dissipation efficiency is insufficient

Engineering Contradiction:
Improveelectronics temperatureVSAvoidoperational lifetime
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The patent implements a rotating pan bearing with vent slots that dynamically aligns with base vent slots during rotation, creating a dynamic airflow management system. This dynamic alignment ensures continuous airflow paths are maintained as the camera pans, allowing consistent cooling of electronics regardless of the camera's rotational position, thereby improving both temperature control and operational reliability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cooling system is segmented into multiple components: base vent slots in the camera base, pan bearing vent slots in the rotating bearing, and multiple airflow paths. This segmentation allows air to flow through distinct channels that collectively cover all heat-generating components, improving overall heat dissipation efficiency while maintaining simple individual components

Inventive Principle:
Principle #1Segmentation

2Loss of energy

If conventional cooling methods are used, then cooling is provided, but heat dissipation efficiency is reduced

Engineering Contradiction:
Improveheat dissipationVSAvoidcooling efficiency
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The pan bearing serves dual functions: enabling camera rotation and managing airflow for cooling. The vent slots in the pan bearing are designed to align with base vent slots during rotation, making the rotational mechanism itself part of the cooling system. This multi-functionality improves cooling efficiency without adding separate cooling mechanisms, thereby reducing energy loss while maintaining high productivity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A pan tilt zoom (PTZ) camera system implements a disc valve system to enhance the cooling of electronics. The disc valve system includes a static camera base and a rotating camera pan bearing. The static camera base has static base vent slots arranged along the perimeter of the static camera base. The rotating camera pan bearing includes at least one pan bearing vent slot that aligns with the static base vent slots. During rotation of the rotating camera pan bearing, the at least one pan bearing vent slot aligns with the static base vent slots enabling movement of air over electronics of the (PTZ) camera system.
