Problem

Existing vehicle safety systems face increased assembly and manufacturing costs due to separate fastening mechanisms for electronic sensors, require more installation steps, and are vulnerable to harsh environmental conditions, especially in compact vehicle spaces.

Innovation Solution

An enhanced electronic assembly with a protective enclosure that isolates electronic components from thermal energy, pressure, and residual material stress, using injection molding techniques and standard satellite housings with apertures for secure mounting and connection, allowing for a compact, durable, and reliable sensor unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate fastening mechanism is used for electronic sensors, then the sensor can be securely mounted to the vehicle, but the assembly complexity and manufacturing costs increase

Engineering Contradiction:

Improvesensor mounting securityVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the electronic sensor assembly with a protective enclosure that integrates mounting features directly into the enclosure structure. The enclosure includes integrated fastening mechanisms such as snap-fit features, threaded inserts, or clip attachments that are built-in during manufacturing, eliminating the need for separate fastening components and reducing assembly steps while maintaining secure mounting.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The protective enclosure serves multiple functions simultaneously: it protects the electronic sensor from environmental factors, provides structural support, and incorporates mounting capabilities. This multi-functional design reduces the number of separate components needed and simplifies the overall assembly while ensuring reliable sensor attachment to the vehicle.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple installation steps are used for electronic sensors, then the sensor can be properly positioned and secured, but the installation time increases

Engineering Contradiction:

Improvesensor installation qualityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The protective enclosure is pre-assembled with the electronic sensor and mounting features integrated during manufacturing. The enclosure includes pre-positioned fastening elements and alignment features that enable direct installation to the vehicle without requiring multiple separate steps for positioning and securing, thereby reducing installation time while maintaining quality.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

By combining the sensor mounting function with the protective enclosure integration, the patent reduces the number of discrete installation steps. The enclosure is designed to be installed as a single unit with the sensor already positioned and secured within it, eliminating the need for separate mounting operations and reducing overall installation time.

Inventive Principle:

Principle #5Merging (Combining)

3Measurement precision

If electronic sensors are placed in tight vehicle spaces, then sensing coverage is optimized, but the design must be more compact which increases manufacturing difficulty

Engineering Contradiction:

Improvesensing coverageVSAvoidcompact design manufacturing

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent employs a nested structure where the electronic sensor is positioned within the protective enclosure, which itself is integrated into the vehicle's existing structure or mounted within constrained spaces. The enclosure is designed with compact dimensions and features that allow it to fit into tight vehicle areas while maintaining adequate space for the sensor to function properly and achieve optimized sensing coverage.

Inventive Principle:

Principle #7Nested doll (Nesting)

4Adaptability or versatility

If electronic sensors are exposed to harsh environmental conditions, then the sensor can detect various vehicle conditions, but the sensor durability decreases

Engineering Contradiction:

Improveenvironmental detection capabilityVSAvoidsensor durability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The protective enclosure is designed as a protective shell that isolates the electronic sensor from harsh environmental conditions such as extreme temperatures, moisture, and vibration. The enclosure provides a controlled internal environment while allowing the sensor to detect external conditions, thereby maintaining sensor durability and reliability while preserving environmental detection capability.

Inventive Principle:

Principle #30Flexible shells and thin films
