Pipe Insulation Assembly With Protected Lap Closure and Cut Markings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe insulation assemblies often suffer damage to the lip portion during shipping and warehousing, which can compromise the integrity of the insulation and installation process.
Innovation Solution
A pipe insulation assembly design featuring a longitudinally extending slit with a releasable tape or butt sealant strip, and an adhesive system that includes a self-sealing lap closure with dimensional markings, allowing for temporary securement during transit and easy installation with visible measurements for precise cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lip portion is left exposed without protective covering, then the adhesive is accessible for bonding, but the lip portion becomes damaged during shipping and warehousing
Solution Approach 1:
A releasable tape is applied to the lip portion before shipping and warehousing to protect it from damage. The tape is removed just before installation, exposing the adhesive for bonding. This preliminary protective action prevents damage during transit while maintaining ease of operation at installation time.
Solution Approach 2:
The releasable tape acts as an intermediary protective layer between the lip portion and external damaging forces during shipping. It temporarily covers the adhesive and lip portion, preventing damage, then is removed to allow the adhesive to perform its bonding function.
2Manufacturing precision
If dimensional markings are placed on the tape, then precise cutting is enabled, but the tape structure becomes more complex
Solution Approach 1:
Dimensional markings are integrated directly into the tape structure, combining the protective function of the tape with the measurement function. This allows precise cutting without requiring separate measurement tools or additional structural elements, thus not increasing device complexity.
Solution Approach 2:
The tape serves multiple functions: protecting the lip portion during shipping, providing dimensional markings for precise cutting, and being easily removable for installation. This multi-functionality eliminates the need for separate protective coverings and measurement tools.
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
The design minimizes damage to the lip portion during shipping and warehousing, facilitates easy installation by providing visible measurements for precise cutting, and ensures a secure bond to the pipe, enhancing the reliability and efficiency of the insulation process.
Implementation Method 1
an adhesive and an internal release liner are located on the extended lip portion
Implementation Method 2
The releasable tape is at least partially disposed over the lip portion. The releasable tape has a releasable adhesive attached to an underside of the tape
