Elevator Blanket Composite Cover for Adjustable Soundproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator blankets require significant custom work for sizing and do not address soundproofing needs effectively.
Innovation Solution
A customizable elevator cover with a body section and strap designed to fit elevator prongs, combined with multiple layers of polymer and foam materials for sound absorption, and fastening mechanisms for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custom-made elevator blankets are used for each elevator size, then protection effectiveness is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent applies universality by designing a single standardized blanket size (54 inches by 96 inches) that can fit multiple elevator sizes through strategic placement and folding. The blanket includes universal features such as straps with openings for prongs, Velcro fasteners, and grommets that can be positioned to accommodate different elevator configurations. This eliminates the need for custom-made blankets for each elevator size while maintaining protection effectiveness.
2Ease of manufacture
If traditional single-layer blankets are used, then manufacturing simplicity is maintained, but soundproofing effectiveness is insufficient
Solution Approach 1:
The patent applies composite materials by constructing the blanket with multiple layers including a outer shell made of durable material, an intermediate layer for sound absorption, and additional reinforcing layers. This multi-layer composite structure provides effective soundproofing while maintaining manufacturing simplicity through standardized layering and bonding processes.
3Ease of manufacture
If standardized blanket sizes are used for multiple elevators, then manufacturing cost and complexity decrease, but fit and protection quality may worsen
Solution Approach 1:
The patent applies dynamics by incorporating adjustable fastening systems including straps with multiple opening positions, Velcro fasteners, and grommets that can be positioned to accommodate different elevator configurations. The blanket can be dynamically adjusted and repositioned to achieve optimal fit and protection quality across various elevator sizes without requiring custom manufacturing.

AI summary
An elevator cover comprising a body section, said body section having a top edge and a bottom edge and left and right-side edges and an interior portion. There is also a strap coupled to the body section, wherein the strap has a top end coupled to a top edge of the body section and a bottom edge coupled to the interior portion of the body section and a plurality of openings disposed in the strap with the openings being disposed below the top edge of the body section. There is also a process for making a cover comprising the steps of making a first layer from a polymer material and then making a middle layer from a foam material, next making a third layer from a polymer material. Next the process includes joining a first layer to a middle layer, and then joining the third layer to the middle layer.
