Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the air conditioning system and cooling-water circulation system are kept separate, then each system can be independently designed and maintained, but the overall system size becomes large, heat-dissipating circuit becomes long, pressure loss increases, and assembly costs increase

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSVolume of stationary object

Solution Approach 1:

The patent integrates the air conditioning system and cooling-water circulation system into a single unified structure. The condenser is placed within the cooling water tank, allowing the refrigerant piping to directly exchange heat with the cooling water. This merging eliminates the need for separate external heat exchangers and reduces the overall system volume while maintaining independent operational functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The condenser (refrigerant piping) is nested inside the cooling water tank, creating a compact hierarchical structure. The refrigerant pipes are positioned within the water tank interior, allowing the cooling water to flow around and cool the refrigerant lines directly. This nesting arrangement minimizes the heat-dissipating circuit length and reduces the overall system footprint.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If the air conditioning system and cooling-water circulation system are kept separate, then system components can be independently replaced, but assembly costs increase and maintenance becomes more difficult

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By integrating the two systems into one compact unit, the patent reduces the number of external connections and interfaces required. The condenser is directly embedded in the water tank, eliminating the need for separate heat exchanger assemblies and reducing assembly complexity. This integration simplifies maintenance procedures while preserving the ability to replace individual components.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If the cooling water tank and condenser thermal exchange are not integrated, then system design is simpler, but thermal exchange efficiency is reduced

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The condenser pipes are nested within the cooling water tank interior, creating direct thermal contact between the refrigerant and cooling water. This arrangement maximizes the heat exchange surface area and minimizes thermal resistance, significantly improving thermal exchange efficiency while maintaining relatively simple system design.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent utilizes the three-dimensional space within the cooling water tank by positioning the condenser pipes vertically or in optimized configurations. This spatial arrangement maximizes the heat exchange surface area within the available volume, enhancing thermal efficiency without increasing system footprint or complexity.

Inventive Principle:

AI summary

The present invention provides an integrated water-cooled air conditioning device, which comprises a cooling water tank device and an air conditioning system. The cooling water tank device includes a cooling water tank. A water tank region is disposed at the bottom of the cooling water tank for accommodating water. The air conditioning system includes a compressor, a condenser, a regulator, and an evaporator connected sequentially by a refrigerant piping. The condenser is formed by spirally bending the refrigerant piping to a spiral hollow tube in the water tank region. Thereby, the air conditioning system and the cooling-water circulation system can be connected integrally for miniaturization. The shortcomings of long heat dissipation loop, high pressure loss, and large size can be solved. Accordingly, the installation costs can be lowered, and the subsequent maintenance management can be convenient.
