Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of insulation over piping elbows is time-consuming and labor-intensive, leading to high costs and inaccuracies due to the ad-hoc shaping of flat insulation sheets on-site, resulting in inefficient insulation and material waste.
Innovation Solution
Preformed insulation fittings, specifically preformed elbow insulation fittings, are manufactured by applying adhesive to insulation gore components, forming them around a mold, and adhering them together to create a fitting that can be easily placed over elbows, reducing on-site labor and improving quality control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flat insulation sheets are shaped on-site to fit elbows, then installation flexibility is maintained, but installation time and labor costs increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-forming insulation fittings to match specific elbow geometries before installation. The fittings are manufactured in advance with precise curved surfaces that correspond to standard elbow angles (45°, 90°, etc.), eliminating the need for on-site shaping operations while maintaining installation flexibility through standardized modular components.
Solution Approach 2:
The patent segments the insulation system into standardized preformed fittings for elbows and separate linear insulation sections for straight pipes. This segmentation allows each component to be optimized independently - elbows receive precision-formed insulation while straight sections use simpler cylindrical covers - and enables modular installation that reduces overall installation time.
2Adaptability or versatility
If flat insulation sheets are shaped on-site, then material can be adapted to fit, but material waste increases due to ad-hoc tailoring
Solution Approach 1:
The patent eliminates material waste by pre-calculating and pre-forming insulation fittings to exact dimensions required for standard elbow geometries. The preliminary design phase determines precise material requirements, and manufacturing processes (such as spray application or molding) deposit or form insulation to match the substrate perfectly, eliminating the excessive material application and subsequent cutting required in on-site shaping.
Solution Approach 2:
The patent changes the physical state and application parameters of insulation material during manufacturing. Techniques such as spray application with controlled atomization, foam expansion to precise densities, or molding processes transform material into fitted forms that conform to elbow geometries without requiring post-installation cutting or trimming, thereby minimizing waste.
3Productivity
If preformed insulation fittings are manufactured, then installation time is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent achieves universality by designing preformed elbow fittings that can be used across multiple standard elbow configurations (different angles, diameters, wall thicknesses) through a family of standardized components. The manufacturing process uses programmable equipment that can be reconfigured via software to produce different fitting types from the same basic tooling, reducing manufacturing complexity while maintaining high installation productivity.
Solution Approach 2:
The patent uses parameter changes in manufacturing equipment settings (spray rate, foam expansion ratio, mold temperature, cutting dimensions) to produce various elbow fitting specifications from the same manufacturing line. This approach avoids the need for completely separate manufacturing processes for each fitting type, managing complexity through digital control while delivering precise preformed products that speed installation.
4Manufacturing precision
If preformed insulation fittings are used, then insulation quality and coverage accuracy improve, but initial manufacturing costs increase
Solution Approach 1:
The patent applies self-service by designing preformed fittings that are self-aligning and self-fitting to standard elbow geometries. The precision-manufactured outer surfaces of the fittings correspond exactly to standard elbow dimensions, allowing installers to simply slip the fitting over the elbow without requiring skilled shaping or extensive measurement, thereby realizing quality improvements while keeping installation labor costs low.
Solution Approach 2:
The patent segments the insulation product line into standardized preformed elbow fittings and modular linear sections that can be manufactured using optimized, high-volume processes. This segmentation enables economies of scale in manufacturing common components while maintaining customization options for special applications, balancing manufacturing cost against the precision and quality benefits of preformed products.

AI summary
A method of manufacturing a preformed elbow insulation fitting includes applying an adhesive to an edge surface of each of a plurality of insulation gore components. After applying the adhesive, the plurality of insulation gore components are formed around a mold. When forming the plurality of gores around the mold, adjacent gores of the plurality of gores are adhered together to form a preformed insulation elbow around the mold. The preformed insulation embow can include a split line space between gore components running radially along a perimeter of the preformed insulation elbow. The preformed insulation elbow is then removed from the mold.
