Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a thermoelectric element is attached to a heat transfer block in a cup holder, then heat can be transferred to a container, but the thermoelectric block itself serves as a resistance causing low thermal conductivity and insufficient cooling and heating effect

Engineering Contradiction:
Improvecooling and heating effectVSAvoidthermal conductivity
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The patent removes the thermoelectric block from the heat transfer path entirely. Instead of using a thermoelectric block that acts as thermal resistance, the design directly attaches the thermoelectric element to the holder body, extracting the problematic component while maintaining the heat transfer function through improved direct contact.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The holder body is divided into distinct functional regions: a first holder body for cooling and a second holder body for heating. Each holder body has a dedicated thermoelectric element attached directly to it, allowing independent optimization of thermal pathways without the interference of a shared thermoelectric block.

Inventive Principle:
Principle #1Segmentation

2Productivity

If a thermoelectric element is used in a cup holder, then cooling and heating function is achieved, but thermal resistance reduces the efficiency of heat transfer

Engineering Contradiction:
Improvecooling and heating efficiencyVSAvoidthermal resistance
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The thermoelectric element is merged directly with the holder body through direct attachment, eliminating the intermediate thermoelectric block that caused thermal resistance. This merging creates a unified thermal pathway that maximizes heat transfer efficiency and minimizes energy loss.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a thermal conductor as an intermediary substance between the thermoelectric element and the holder body. This thermal conductor fills gaps and improves contact, acting as a mediator that enhances heat transfer while being thermally conductive itself, unlike the problematic thermoelectric block.

Inventive Principle:
Principle #24Intermediary (Mediator)
