Solution Overview

Problem

Conventional ground embedded imaging devices with drainage functions face issues with ineffective water discharge when roads lack drainage ditches, leading to image distortion due to moisture accumulation.

Innovation Solution

The ground embedded imaging device incorporates a barrel housing unit with a water collecting chamber, a translucent window, and an automatic draining unit featuring a water expelling driver to smoothly guide and expel water from the chamber, preventing moisture accumulation around the imaging module.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a drainage pipe is used to discharge water downwardly, then water can be discharged to a drainage ditch, but image distortion occurs when drainage ditches are not available

Engineering Contradiction:

Improvewater discharge reliabilityVSAvoidadaptability to different road conditions

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The drainage system is designed with both a downward drainage pipe and an outward water ejecting assembly, allowing the system to dynamically adapt its water discharge direction based on external conditions. The control unit activates the water ejecting assembly when drainage ditches are absent, enabling flexible response to different road environments.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The sensor detects the presence or absence of drainage ditches and automatically controls the water ejecting assembly without human intervention. The system serves itself by monitoring environmental conditions and adjusting its water discharge mechanism accordingly.

Inventive Principle:

Principle #25Self-service

2Quantity of substance

If water is allowed to flow into the water collecting chamber, then water can be collected for discharge, but moisture accumulates around the window portion affecting imaging

Engineering Contradiction:

Improvewater collection capacityVSAvoidmoisture accumulation around window

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The water ejecting assembly extracts water from the water collecting chamber and discharges it outward through a nozzle positioned away from the window portion. This separates the water collection function from the imaging area, preventing moisture accumulation while maintaining effective water discharge.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The water ejecting assembly acts as an intermediary mechanism between the water collecting chamber and the external environment. It transfers water from the chamber to the outside world through a controlled ejection path that does not interfere with the window portion or imaging module.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If a conventional drainage pipe is used, then the structure is simple, but water cannot be discharged smoothly when drainage ditches are absent

Engineering Contradiction:

Improvedrainage structure simplicityVSAvoidwater discharge effectiveness

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The drainage system incorporates multiple functions: the downward drainage pipe handles discharge to drainage ditches, while the water ejecting assembly with sensor and control unit provides alternative discharge capability when ditches are absent. This multi-functional design ensures reliable water discharge across various road conditions without significantly increasing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A ground embedded imaging device includes a barrel housing unit (200), an electronic element unit (6) and an automatic draining unit (7). The barrel housing unit (200) has a water collecting chamber (241, 20), a translucent window portion (245, 342) at an upper end of the barrel housing unit, a water conducting hole (443, 412) to conduct water from outside to the water collecting chamber, and a water deflecting recess portion (444, 411) in spatial communication with the water conducting hole and disposed below the ground surface. The electronic element unit (6) includes an imaging module (8) oriented toward the window portion (245, 342). The automatic draining unit (7) includes a water expelling driver (71) which is actuated to expel water from the water collecting chamber (241, 20). Water is prevented from accumulating around the window portion so that the imaging module operates correctly.
