Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Polymer plumber's strapping tends to uncoil and tangle when removed from packaging, leading to user frustration and material wastage, and existing cutting methods can result in sharp edges.
Innovation Solution
A dispenser with a housing, material track, advancement mechanism, and integrated cutting mechanism, featuring a spring-biased actuator that moves between advancement and cutting positions to manage and cut the strapping material efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If polymer strapping is removed from packaging, then it becomes easier to work with and cut, but it tends to uncoil and tangle
Solution Approach 1:
The dispenser divides the strapping management function into separate components: a storage area for the coil, a dispensing mechanism for controlled extraction, and a cutting mechanism. This segmentation allows the strapping to be stored in a stable coiled state while enabling easy cutting when needed, resolving the contradiction between maintaining coil stability and ease of cutting.
Solution Approach 2:
The dispenser acts as an intermediary device between the coiled strapping and the user. It provides a structured environment that maintains the coil's stability while offering a user-friendly interface for measuring and cutting the material, thus resolving the contradiction between coil stability and ease of operation.
2Strength
If metal strapping is used, then it provides strong securing capability, but it requires heavy snippers and produces sharp edges
Solution Approach 1:
The patent employs a disposable polymer strapping material that replaces metal strapping. While polymer is less strong than metal, it eliminates the harmful sharp edges and heavy cutting requirements, providing sufficient securing capability for most plumbing applications while significantly improving safety and ease of use.
Solution Approach 2:
The patent converts the weakness of polymer material (comparing it to metal) into a benefit by eliminating the harmful sharp edges and heavy cutting requirements. The polymer strapping, while not as strong as metal, provides adequate securing capability without the safety hazards and operational difficulties associated with metal strapping.
3Object-affected harmful factors
If polymer strapping is used, then it is easier to cut and less likely to injure users, but it uncoils and tangles upon removal from packaging
Solution Approach 1:
The dispenser segments the strapping into a stable coiled storage portion and a controlled dispensing portion. This allows the majority of the strapping to remain stably coiled while enabling easy access and cutting of the needed length, resolving the contradiction between coil stability and ease of operation.
Solution Approach 2:
The dispenser serves as an intermediary that maintains the coil's stability while providing a user-friendly interface for measuring and cutting. It protects the user from injury by containing the cutting operation within a controlled mechanism, thus resolving the contradiction between user safety and coil stability.
4Volume of moving object
If strapping is stored in a coil, then it is compact and easy to store, but it becomes loose and tangled when uncoiled
Solution Approach 1:
The dispenser segments the strapping into a compact coiled storage portion and a controlled dispensing portion. The coil remains compact and intact within the storage area, while the dispensing mechanism allows controlled uncoiling of only the needed length, preventing tangling and maintaining coil integrity.
Solution Approach 2:
The dispenser acts as an intermediary that maintains the coil's compact and stable configuration while providing a controlled method for dispensing the strapping. It prevents the coil from becoming loose or tangled by managing the uncoiling process through a structured dispensing mechanism.

AI summary
A dispenser for dispensing a selectable amount of material from an amount of stored material. The dispenser includes a housing having a material track and material storage area, a material-advancement mechanism disposed within said housing, a material-cutting, mechanism, and an actuator. The actuator has a first end being operatively engaged with said first mechanism and an opposing second opposing end being operatively engaged with said second mechanism. The actuator is spring-biased to a non-compressed position via at least first and second springs and is also selectably shiftable to a selectable, material-advancement position and a selectable, material-cutting position.
