Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article falling prevention devices rely on electrically operating components, such as seismometers and actuators, which require a power source and fail during earthquakes, rendering them ineffective.
Innovation Solution
A mechanical article falling prevention device utilizing rotating rods, load support members, elastic members, and falling prevention members that move through a mechanical configuration to prevent articles from falling due to vibrations like earthquakes, without any electrically operating components, ensuring continuous functionality even during power failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrically operating components (seismometer and actuator) are used to detect earthquakes and activate fall prevention, then the device can automatically respond to earthquakes, but the device requires a power source and fails during power failures
Solution Approach 1:
The patent replaces the electrical system (seismometer and actuator) with a purely mechanical system. The mechanical lever arm is positioned to automatically contact and support articles when tilted during earthquakes, eliminating the need for electrical components, power sources, and electronic sensors while maintaining earthquake response capability
Solution Approach 2:
The mechanical lever arm system is designed to automatically respond to earthquake tilting without external control. The geometry of the lever arm and its pivot point enable it to self-activate and provide support during seismic events, eliminating dependency on powered systems
2Reliability
If a mechanical configuration without electrically operating components is used, then the device functions during power failures and earthquakes, but the device complexity increases with rotating rods, link members, and elastic members
Solution Approach 1:
The patent employs elastic members (springs) as counterweights to balance the lever arm and rotating rods. These elastic members provide the necessary mechanical force to maintain the lever arm in position and enable automatic response during earthquakes without requiring complex control systems
Solution Approach 2:
The mechanical system is divided into modular components: rotating rods, link members, elastic members, and the lever arm. This segmentation allows each component to perform a specific function independently, simplifying the overall design and maintenance while achieving reliable earthquake response

AI summary
Providing a new article falling prevention device capable of preventing an article placed on a mounting plate from falling due to vibration such as an earthquake without using any electrically operating member as a component at all. A left end of a load support member is connected to a left rotating rod 15 pivotally supported rotatably by a left support shaft 13 disposed at a front end side middle portion or a rear end side middle portion, a right end of the load support member is connected to a right rotating rod 16 pivotally supported rotatably by a right support shaft 14 disposed at a front end side middle portion or a rear end side middle portion, and the load support member 17 supports all or part of the load of an article W. In a case where the load support member 17 supports the load of the article W, a falling prevention member 45 moves down or rotates when the left rotating rod 15 and the right rotating rod 16 rotate, the falling prevention member 45 is provided on the front side of the article W when the falling prevention member 45 is most lowered, and when the falling prevention member 45 is most lowered or rotate, an insertion space into which an article lifting unit is inserted from the front side is formed below the falling prevention member 45.
