Protector for installation on floor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial sites face safety accidents due to collisions between forklifts and vertical posts of iron shelves, where existing solutions like alarm rods and rack post protecting devices do not adequately address the need for impact absorption on the floor surface.
Innovation Solution
A floor protector comprising a guard part, an intermediate body made of softer material, two or more elastic bodies, and stud bolts that compress during collisions to absorb impact, with the guard part and base part fixed to the floor surface through the intermediate body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alarm rods or rack post protecting devices are installed, then collision warning is improved, but impact absorption capability is insufficient
Solution Approach 1:
The patent applies beforehand cushioning by installing elastic bodies (spring elements) within the protector structure that are pre-compressed or pre-positioned to absorb impact energy. When a forklift collides with the vertical post, these elastic bodies compress to cushion the shock, preventing direct transmission of impact forces to the post and floor.
Solution Approach 2:
The patent uses composite materials by combining different material properties in the protector structure - rigid components for structural support and alarm function, combined with elastic/cushioning materials for impact absorption. This composite approach allows the single device to simultaneously provide warning, structural integrity, and shock absorption.
2Strength
If a rigid protector structure is used, then structural strength is improved, but impact absorption is reduced
Solution Approach 1:
The patent segments the protector into distinct functional components: rigid alarm rod elements for warning and structural support, elastic bodies for impact absorption, and mounting components for installation. This segmentation allows each component to perform its specialized function - the rigid parts provide strength and warning, while the elastic parts absorb impact energy.
Solution Approach 2:
The patent applies parameter changes by utilizing the elastic properties of the elastic bodies, which change their physical state from uncompressed to compressed during impact. This parameter change (compression) allows the structure to absorb impact energy dynamically while maintaining overall structural integrity through the rigid components.
3Object-affected harmful factors
If multiple components are added for impact absorption, then impact reduction is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated protector device: the alarm rod provides collision warning, the elastic bodies provide impact absorption, and the mounting structure provides installation and positioning. This merging consolidates what could be separate devices into one unified component, reducing overall system complexity while maintaining all necessary functions.
Solution Approach 2:
The patent achieves universality by designing the protector to perform multiple functions simultaneously - warning (alarm rod), impact absorption (elastic bodies), and structural support (mounting components). This multi-functional design eliminates the need for separate warning devices and cushioning devices, simplifying the overall system while providing comprehensive protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively reduces the impact of collisions by compressing the elastic bodies and softer intermediate body, alerting drivers while minimizing damage to vertical posts.
Implementation Method 1
an elastic body capable of being compressed according to a degree of impact on the bottom surface of the intermediate body so as to absorb or reduce the impact when receiving an external force
Implementation Method 2
a rear surface portion coupled to a body part which is a first component of the intermediate body is made of a softer material than the body part and simultaneously, the elastic body and the soft intermediate body are compressed in a collision direction when applying an external force

AI summary
A protector for installation on a floor includes: a guard part comprising a contact surface portion having first screw through-holes formed therethrough, a middle portion which is coupled upward from the edge of the contact surface portion to be primarily impacted, and wing portions integrally coupled to both sides of the middle portion, respectively; a base part having third screw through-holes formed therethrough so as to be fixed to a floor surface while being brought into contact with the floor surface; an intermediate body disposed between the guard part and the base part and having second screw through-holes formed therethrough; and stud bolts passing through the guard part, the intermediate body, and the base part so as to fix the base part to the floor surface, wherein when an external force is applied, the elastic and flexible intermediate body is compressed in a collision direction to effectively reduce the impact.
