Object Detection Device Angle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object detection devices face challenges in reducing size and cost while enabling easy attachment and detachment of an external automatic angle adjustment unit, which complicates the adjustment process and increases device size due to internal motor systems and complex structural components.
Innovation Solution
The object detection device incorporates a simplified angle adjustment mechanism with horizontal and vertical adjustment components that are externally engageable, featuring knurled surfaces and screw-driven engagement, allowing for easy attachment and detachment of an external automatic angle adjustment unit, reducing the device's size and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an automatic angle adjustment section with driving motor and control section is incorporated in the device, then automatic angle adjustment function is achieved, but device size and cost increase
Solution Approach 1:
The patent extracts the automatic angle adjustment function from the main device body by providing an external adjustment unit that can be attached to the side surface. This separates the automation function into an independent module, allowing the main device to remain compact while still achieving automatic angle adjustment when needed.
Solution Approach 2:
The angle adjustment mechanism is divided into separate functional components: the main device body, the external adjustment unit with motor, and the engagement mechanism. This segmentation allows each component to be optimized independently and enables flexible configuration based on user needs.
2Ease of operation
If vertical and horizontal adjustment components are spaced apart, then adjustment functionality is achieved, but attachment and detachment of external adjustment unit becomes difficult
Solution Approach 1:
The patent merges the vertical and horizontal adjustment components into a closely integrated arrangement on the side surface of the device body. This unified structure provides a compact engagement interface that allows the external adjustment unit to be easily attached and detached while maintaining full adjustment functionality.
3Extent of automation
If adjustment components are positioned to allow external engagement, then external automatic adjustment is enabled, but structural complexity increases
Solution Approach 1:
The engagement components are designed with universal functionality to serve multiple purposes: they provide mechanical attachment for the external adjustment unit, transmit rotational motion for angle adjustment, and maintain structural integrity. This multi-functionality reduces the need for separate specialized components.

AI summary
A horizontal adjustment-engagement member (33) of an object detection device (D) drives the horizontal rotation component (32) to adjust a horizontal angle of a detection unit (11, 12), and a vertical adjustment-engagement member (37) drives the vertical rotation component (36) to adjust a vertical angle of a detection unit. Both adjustment-engagement members (33 and 37) are positioned adjacent to each other at fixed positions such that portions thereof are exposed on a front surface of the device (D), are removably engaged with an external automatic angle adjustment unit (70) from front surfaces, and are automatically adjusted by a driving force of the automatic angle adjustment unit (70) based on a signal level of a detection signal outputted by level output section (7).
