Solution Overview
Problem
Conventional insulation spraying and blowing machines face difficulties in efficiently processing and applying particulate insulation materials from compressed bales or bags, requiring manual handling and complex machinery for material separation and distribution, which increases size, complexity, and operational challenges.
Innovation Solution
A system comprising a power supply and a machine with a hopper and auger mechanism that processes insulation materials by rotating helical flighting and paddles to separate and propel the material through an airlock for pneumatic delivery, integrated with a vehicle for convenient and economical application, allowing full bag feeding and minimizing operator exposure to power supply noise and fumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional insulation spraying machines use compressed bales or bags of insulation material, then the insulation material can be transported efficiently, but the material becomes difficult to process and feed through air hoses to dispensing nozzles
Solution Approach 1:
The auger mechanism segments the compressed insulation material into individual particles and fibers as it rotates and conveys the material through the hopper, transforming it from a compressed mass into a processable particulate form that can be easily fed through the air hose to the dispensing nozzle
Solution Approach 2:
The patent replaces complex manual separation and movement devices with an automated auger mechanism that mechanically processes the insulation material. The auger's rotating helical flighting and paddles automatically separate, chop, and convey the material, eliminating the need for multiple separate mechanical separation devices
2Duration of action of moving object
If commercial hoppers are made large to hold sufficient insulation material, then continuous operation is enabled, but the overall size and complexity of the machine increases significantly
Solution Approach 1:
The auger mechanism performs multiple functions simultaneously: it conveys the insulation material from the hopper, separates it into particles, chops it into smaller pieces, and prepares it for pneumatic delivery. This multi-functionality eliminates the need for separate devices for each operation, reducing overall machine complexity while enabling continuous operation
Solution Approach 2:
The patent combines the hopper, auger mechanism, material separation devices, and conveyance systems into an integrated unit. The auger serves as both a conveyance element and a separation mechanism, merging functions that would traditionally require separate components into a single compact assembly
3Volume of moving object
If small volume machines are used for insulation application, then the machine size is reduced, but continuous attention is required and the insulation must be broken up into smaller pieces
Solution Approach 1:
The auger mechanism operates continuously to convey and process the insulation material, eliminating the need for operator intervention to break up material or refill the hopper. The continuous rotation of the auger maintains constant material flow and processing, enabling unattended operation while keeping the machine compact
4Productivity
If conventional insulation processing machines are used, then material can be processed, but manual handling is required and the machinery becomes complex with multiple separation and movement devices
Solution Approach 1:
The auger mechanism is self-sufficient, automatically performing the separation, chopping, and conveyance functions without requiring external intervention. The rotating auger with its helical flighting and paddles inherently performs the material processing functions, eliminating the need for multiple separate separation and movement devices

AI summary
A system for processing material has a power supply and a machine having a hopper for receiving and passing material to an auger. The auger has a shaft with an axis about which it rotates, a helical flighting mounted to the shaft, pins mounted to the helical flighting, and paddles mounted to the shaft. The radial outer edge of the helical flighting is crenelated with periodic notches that form rectangular blades on the helical flighting. The pins are rotationally and angularly aligned with leading edges of the rectangular blades. The system may include a vehicle, such as a trailer, having first and second compartments separated by a partition. The power supply is located in the first compartment and has a power supply member extending though the partition. The machine is located in the second compartment and coupled to the power supply member.
