Solution Overview

Problem

Camera modules in vehicles face issues with airtightness and cable stability due to cable exposure, leading to moisture and dust invasion and potential electrical connection interruptions during vehicle operation.

Innovation Solution

A camera module design featuring a cable accommodating part with a closure system, including a first closure part and a second closure part, which are press-fitted and clamped by a cap to maintain airtightness and stabilize the cable, ensuring it extends externally while preventing moisture and dust ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cable is drawn out from the second exterior member, then the cable can extend externally for electrical connection, but the airtightness of the second exterior member is deteriorated allowing moisture and dust to invade

Engineering Contradiction:

Improvecable extensionVSAvoidmoisture and dust invasion

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The closure is divided into two parts: a first closure part that seals the cable accommodating part and a second closure part that extends outward to seal around the cable. This segmentation allows the cable to extend externally while maintaining airtightness at both the internal and external interfaces.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The closure acts as an intermediary component between the cable and the second exterior member. It provides a sealing interface that allows the cable to pass through while preventing moisture and dust from entering the camera module interior.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the cable is drawn out from the second exterior member, then the cable can extend externally for electrical connection, but the cable may be shaken causing electrical connection interruption

Engineering Contradiction:

Improvecable extensionVSAvoidelectrical connection stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The second closure part is designed to clamp the cable in advance before external connections are made. This preliminary clamping action secures the cable position and prevents shaking that could cause electrical connection interruptions during vehicle operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The closure provides localized clamping and sealing at the cable exit point. This localized action stabilizes the cable where it is most vulnerable to movement while allowing the rest of the system to function normally.

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If a closure system with first and second closure parts is used to maintain airtightness, then moisture and dust invasion is prevented, but the device complexity increases

Engineering Contradiction:

Improvemoisture and dust preventionVSAvoidclosure structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The first and second closure parts are integrated into a single closure component that performs both sealing functions simultaneously. This merging reduces the number of separate parts needed while maintaining the dual functionality of internal and external sealing.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The closure serves multiple functions: it seals the cable accommodating part internally, seals around the cable externally, and provides mechanical support for the cable. This multi-functionality reduces the need for additional separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)
