Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively and promptly alert individuals to slippery surfaces, particularly when employees cannot immediately address hazardous conditions due to toxicity or transparency of fluids, leading to increased risk of slip and fall accidents and associated litigation costs.
Innovation Solution
A warning apparatus featuring a light emitting device mounted with a light-refracting liquid or powder added to cleaning solutions, which reflects light to visibly indicate slippery surfaces, ensuring awareness of hazardous conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If employees manually monitor and clean slippery surfaces, then they can address hazardous conditions, but they cannot immediately detect or respond to all hazards especially when out of line of sight or when multiple locations require attention
Solution Approach 1:
The cleaning solution automatically performs the detection function by changing color when it comes into contact with slippery substances, eliminating the need for employees to manually inspect every area. The system serves itself by providing visual alerts without human intervention.
Solution Approach 2:
The patent replaces the mechanical/physical inspection method (employees walking and looking) with a chemical indication system. The pH-sensitive dye provides automatic visual detection, substituting human sensory inspection with a chemical sensing mechanism.
2Ease of manufacture
If transparent cleaning fluids are used on slippery surfaces, then the surfaces can be cleaned and treated, but the transparency of the fluids makes the hazardous condition harder to detect
Solution Approach 1:
The patent employs pH-sensitive dyes that change color based on the pH of substances they contact. When the transparent cleaning solution encounters acidic or basic slippery substances, it undergoes a visible color change, making the previously invisible hazard clearly detectable.
Solution Approach 2:
The patent changes a physical parameter (color) of the cleaning solution based on chemical parameter changes (pH levels). This allows the solution to maintain its cleaning properties while simultaneously providing visual information about hazardous conditions through color indication.
3Reliability
If employees perform frequent sweep checks to detect slippery surfaces, then they can identify hazards, but it requires significant time and interrupts their other tasks
Solution Approach 1:
Instead of periodic discrete inspections, the patent enables continuous monitoring. As employees apply the cleaning solution continuously during normal cleaning operations, the hazard detection function operates continuously as well, eliminating the need for separate sweep check interruptions.
Solution Approach 2:
The cleaning solution performs multiple functions simultaneously: it cleans the surface and detects hazardous substances. This multi-functionality eliminates the need for separate detection activities, allowing employees to accomplish both cleaning and monitoring in a single operation.
