Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the image acquisition apparatus is installed outdoors on large machines, then visual blind spots can be monitored, but the apparatus is exposed to direct sunlight causing temperature rise

Engineering Contradiction:

Improveoutdoor monitoring capabilityVSAvoidapparatus temperature

Core Design Contradiction:

Adaptability or versatilityVSTemperature

Solution Approach 1:

A sunshading part is introduced as an intermediary element between the sunlight and the image acquisition apparatus. This sunshading part blocks direct sunlight from reaching the apparatus, thereby mediating the harmful thermal effect while allowing the apparatus to remain installed outdoors for monitoring purposes

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the sunshading part is placed close to the upper box body, then shading effect is improved, but heat transfer from the sunshading part to the apparatus increases

Engineering Contradiction:

Improvesunlight blocking effectivenessVSAvoidheat transfer to apparatus

Core Design Contradiction:

Object-affected harmful factorsVSLoss of energy

Solution Approach 1:

The space between the sunshading part and the upper box body forms an air flow layer that utilizes natural convection and airflow to remove heat. The air acts as a cooling medium, carrying away heat from the apparatus while the sunshading part remains positioned to effectively block sunlight

Inventive Principle:

Principle #29Pneumatics and hydraulics

Solution Approach 2:

The air flow layer creates a thermal isolation environment between the sunshading part and the apparatus. This layer of air acts as a thermal barrier, preventing direct heat transfer while maintaining the shading function

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

3Loss of information

If data processing is performed on acquired pictures, then useful information is extracted, but heat generation from processing increases apparatus temperature

Engineering Contradiction:

Improveinformation processing capabilityVSAvoidapparatus temperature

Core Design Contradiction:

Loss of informationVSTemperature

Solution Approach 1:

The air flow layer, which could be seen as empty space, is utilized as a heat dissipation channel. The natural airflow in this layer carries away heat generated from both sunlight exposure and data processing operations, converting a potential weakness into a beneficial cooling mechanism

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
