Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-width air outlet is used in the heat dissipation assembly, then the structure is simple, but the cold air is wasted when the panel width varies and uniform cooling cannot be ensured

Engineering Contradiction:
Improveadaptability to varying panel widthsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The air outlet width is made adjustable through a sliding mechanism where the inner housing can move relative to the outer housing along the first direction. This dynamic adjustment allows the air outlet width to match different panel widths, preventing cold air waste and ensuring uniform cooling while adapting to various display configurations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the geometric parameter of the air outlet width by adjusting the position of the inner housing. By varying the overlapping width between the first and second air outlets along the first direction, the system adapts to different panel widths without requiring multiple fixed outlet designs, thus improving adaptability while controlling structural complexity.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the air outlet width is increased to match wider panels, then more cold air is available for wider panels, but cold air is wasted on narrower panels

Engineering Contradiction:
Improveheat dissipation efficiencyVSAvoidcold air waste
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The sliding mechanism enables the air outlet width to dynamically match the actual panel width being cooled. When the panel is wider, the air outlets are positioned to provide sufficient coverage; when the panel is narrower, the outlets are adjusted to prevent excess cold air waste, thereby optimizing heat dissipation efficiency and energy utilization across different configurations.

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If the first air outlet and second air outlet are completely separate, then airflow is simple to manage, but cooling coverage is insufficient for varying panel widths

Engineering Contradiction:
Improveair outlet coverage areaVSAvoidairflow management complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent merges the first and second air outlets by allowing them to overlap along the first direction, forming an air outlet overlapping part. This overlapping region creates a combined cooling coverage area that can accommodate varying panel widths. The overlapping structure integrates the airflow paths of both outlets, providing comprehensive cooling coverage while managing airflow through a unified design rather than completely separate outlets.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A heat dissipation assembly and a display apparatus are described. The heat dissipation assembly includes an outer housing and an inner housing. One end of the outer housing is provided with a first air inlet, and a housing wall of the outer housing is provided with a first air outlet extending along a first direction. One end of the inner housing is provided with a second air inlet, and a housing wall of the inner housing is provided with a second air outlet extending along the first direction. The first air outlet and the second air outlet at least partially overlap to form an air outlet overlapping part. A width of the air outlet overlapping part is adjustable. Therefore, a width of an air outlet of the heat dissipation assembly is adjustable according to the heat dissipation demand.
