Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the intelligent watch is designed with a fully sealed structure for waterproof effect, then waterproof performance is improved, but heat dissipation performance deteriorates

Engineering Contradiction:

Improvewaterproof performanceVSAvoidheat dissipation performance

Core Design Contradiction:

ReliabilityVSTemperature

Solution Approach 1:

The watch strap is divided into multiple functional sections: a first strap body section with heat dissipation function, a second strap body section without heat dissipation function, and a connection section. This segmentation allows the heat dissipation structure to be localized to specific areas while maintaining the overall sealed structure of the watch for waterproofing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A heat conduction section is introduced as an intermediary element between the heat-generating watch body and the external environment. This heat conduction section includes heat absorption portions that contact the watch body and heat dissipation portions that extend outward, serving as a thermal bridge that transfers heat from the sealed watch interior to the exterior without compromising the waterproof seal.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If more electronic components are added to increase device functions, then device functionality is improved, but heat generation increases

Engineering Contradiction:

Improvedevice functionalityVSAvoidheat generation

Core Design Contradiction:

Adaptability or versatilityVSTemperature

Solution Approach 1:

The heat dissipation function is extracted and separated from the main watch body structure, being implemented independently through the strap's heat conduction section. This allows the watch to maintain its sealed waterproof design while adding dedicated heat management capability to handle the thermal load from multiple electronic components.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The heat dissipation pathway is extended into the spatial dimension by having the heat dissipation portion outwardly extend from the heat absorption section through the strap body. This creates a three-dimensional heat transfer path that moves heat away from the watch body in a direction perpendicular to the watch face, effectively managing thermal load without interfering with the watch's functional components.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
