Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If heat is transferred to the base portion for dissipation, then heat transfer from electronic components is improved, but heat dissipation efficiency decreases when mounted to ceiling or wall

Engineering Contradiction:

Improveheat transferVSAvoidheat dissipation efficiency

Core Design Contradiction:

TemperatureVSLoss of energy

Solution Approach 1:

The base portion is divided into functionally distinct regions: a substrate holding portion for mounting electronic components and a heat dissipating portion with heat dissipation fins. This segmentation allows heat to be transferred from the substrate to the base portion while simultaneously providing a dedicated pathway for efficient heat dissipation to the atmosphere, resolving the contradiction between heat transfer and heat dissipation efficiency.

Inventive Principle:

Principle #1Segmentation

2Temperature

If heat is transferred to the entire base portion, then heat dissipation capacity is increased, but adjacent components may be unintentionally thermally damaged

Engineering Contradiction:

Improveheat dissipation capacityVSAvoidthermal damage to adjacent components

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The base portion is designed with non-uniform thermal properties through local quality differentiation. The heat dissipating portion with heat dissipation fins is positioned to receive heat from the substrate, while adjacent areas are designed with different thermal characteristics to protect nearby components. This localized thermal management allows high heat dissipation capacity in the required area while preventing thermal damage to adjacent components through spatial and thermal property differentiation.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If the camera case is mounted to ceiling or wall for stable installation, then installation stability is improved, but heat dissipation to atmosphere significantly decreases

Engineering Contradiction:

Improveinstallation stabilityVSAvoidheat dissipation efficiency

Core Design Contradiction:

Stability of the object's compositionVSLoss of energy

Solution Approach 1:

The base portion is segmented into a substrate holding portion for stable mounting to ceiling or wall and a heat dissipating portion with heat dissipation fins that extends toward the atmosphere. This segmentation enables the mounting function to be separated from the heat dissipation function, allowing stable installation while maintaining effective heat dissipation capacity through the finned structure that interfaces with ambient air.

Inventive Principle:

4Reliability

If a locking mechanism is added to prevent rattling, then reliability in outdoor environments is improved, but device complexity increases

Engineering Contradiction:

Improveresistance to wind pressure and vibrationVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is merged with the existing mounting structure of the camera case. The case includes a locking mechanism that integrates with the attachment structure to ceiling or wall, providing resistance to wind pressure and vibration without requiring a completely separate locking system. This merging approach enhances reliability in outdoor environments while minimizing the increase in device complexity by utilizing and enhancing existing structural elements.
