Solution Overview

Problem

Radar antenna systems face challenges in reducing apparatus size due to the use of link mechanisms for adjusting antenna angles, which increases the overall size and complicates mounting and adjustment processes, especially in in-vehicle applications where space and cost are concerns.

Innovation Solution

A wave energy radiating apparatus incorporating a linear-movement generator, direction changer, and force applying member, including a stepping motor and cylindrical body, allows for precise adjustment and maintenance of radiation direction without increasing the apparatus size, utilizing a mechanism that converts rotational motion into linear movement to adjust the antenna board's angle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a link mechanism is used to adjust the antenna angle, then the antenna direction can be changed, but the apparatus size increases

Engineering Contradiction:
Improveantenna direction adjustmentVSAvoidapparatus size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The patent replaces the traditional mechanical link mechanism with a linear-movement generator that directly drives the antenna board. This substitution eliminates the need for complex linkages while achieving the same directional adjustment function, thereby reducing apparatus size while maintaining ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the dimensional approach by using linear movement along the antenna board surface rather than rotational movement through link mechanisms. The linear-movement generator moves parallel to the antenna board surface, converting rotational motion into linear displacement, which reduces the spatial requirements and overall apparatus volume.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a link mechanism is used for antenna adjustment, then the antenna angle can be changed, but the device complexity increases

Engineering Contradiction:
Improveantenna direction adjustmentVSAvoidmechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the complex mechanical link mechanism with a linear-movement generator that provides direct drive capability. This substitution simplifies the overall device structure by eliminating multiple linkage components, joints, and associated mounting requirements, thereby reducing device complexity while maintaining the ability to adjust antenna direction.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention extracts and removes the unnecessary link mechanism components from the system, retaining only the essential linear-movement generator and its direct drive connection to the antenna board. This extraction eliminates complex intermediate mechanisms while preserving the core functionality of antenna direction adjustment.

Inventive Principle:
Principle #2Taking out (Extraction)

3Volume of moving object

If the linear-movement generator is provided on the antenna board surface, then the apparatus size is reduced, but the force application against turning becomes challenging

Engineering Contradiction:
Improveapparatus sizeVSAvoidforce application for maintaining attitude
Core Design Contradiction:
Volume of moving objectVSForce

Solution Approach 1:

The patent introduces a force applying member as an intermediary component that transmits the output force from the linear-movement generator to the antenna board. This intermediary mechanism effectively transfers the linear motion force into the rotational force needed to counteract gravitational effects and maintain the antenna board's attitude, solving the force application challenge while keeping the generator compact on the board surface.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The force applying member is designed as a simple, lightweight component that provides the necessary force transmission without adding significant complexity or size. This approach uses a straightforward mechanical element rather than a complex force multiplication system, keeping the overall apparatus compact while adequately addressing the force application requirement.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
