Multi-Axis Inertial Force Sensor With Segmented Inclined Blocks

Solution Overview

Problem

Conventional multi-axis inertial force sensors face challenges in mounting multiple sensors on a pedestal with complex shapes, leading to increased costs and processing time due to the need for multiple inclined surfaces.

Innovation Solution

A multi-axis inertial force sensor configuration using blocks with inclined surfaces and positioning portions allows sensors to be easily installed on a pedestal, reducing the complexity of mounting and processing by eliminating the need for multiple inclined surfaces on a single block.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple inclined surfaces are provided on a single pedestal block, then multiple sensors can be mounted to detect multiple axes, but the manufacturing complexity and processing time increase

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pedestal is divided into multiple separate blocks, each with a single inclined surface. Each block is mounted independently on the substrate, allowing multiple sensors to be distributed across different blocks rather than concentrating multiple inclined surfaces on a single complex pedestal structure.

AI summary

A multi-axis inertial force sensor includes a mounting material, blocks, and sensors. Each block has a positioning portion that determines its position relative to a contact partner. A pedestal is formed by an assembly of the blocks where the positions are determined relative to each other based on the positioning portion and where inclined surfaces are oriented in different directions. The sensors are respectively arranged on the inclined surfaces of the pedestal so that the main axes are oriented in different directions to detect vector components of inertial force corresponding to the main axes.
