Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balloon inflators face issues with high motor temperatures leading to premature wear and inflation of balloons with warm air, which causes deflation, especially when inflating large foil balloons with self-sealing valves, and lack the ability to adjust for different types of balloons.
Innovation Solution
A balloon inflator with a bypass motor that separates working air and motor cooling air paths, featuring a movable inflation nozzle and interchangeable nozzle adaptors to adjust operating parameters and pressures for various balloon types, reducing heat buildup and preventing self-sealing valve displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a through-flow motor is used to inflate balloons, then the motor can cool itself through the air flow, but the motor temperature rises continuously causing premature wear and balloon deflation
Solution Approach 1:
The patent divides the air flow into two separate paths: a working air path that inflates the balloon and a motor cooling air path that cools the motor. The working air path delivers air through the inflation nozzle to the balloon, while the motor cooling air path draws air through the motor and exhausts it separately. This segmentation prevents the motor from overheating while maintaining reliable balloon inflation.
Solution Approach 2:
The patent extracts the motor cooling function from the balloon inflation function by providing a dedicated motor cooling air path that is separate from the working air path. This extraction allows the motor to be cooled independently without affecting the balloon inflation process, preventing temperature buildup and extending motor lifespan.
2Productivity
If high inflation pressure is used to fill balloons quickly, then productivity increases, but the self-sealing valve of large foil balloons may be displaced
Solution Approach 1:
The patent incorporates a movable inflation nozzle that can dynamically adjust its position and opening size based on the balloon type and inflation requirements. The nozzle can be positioned to provide different degrees of restriction, allowing high pressure for small balloons and controlled pressure for large foil balloons with self-sealing valves, thus preventing valve displacement while maintaining productivity.
Solution Approach 2:
The patent changes the pressure parameter dynamically by providing a movable inflation nozzle that can adjust the air flow characteristics. By modifying the nozzle position and opening size, the system can deliver high pressure when needed for small balloons and reduce pressure to safe levels for large foil balloons, preventing valve displacement while maintaining efficient inflation.
3Adaptability or versatility
If a narrow inflation nozzle is used to receive balloon necks, then the nozzle fits all balloon types, but air flow is restricted and motor temperature increases
Solution Approach 1:
The patent provides a universal inflation nozzle assembly that can accommodate multiple balloon types through interchangeable adaptors. Each adaptor is designed for specific balloon types (latex, small foil, large foil) and provides the appropriate fit and air flow characteristics. This multi-functionality allows the system to maintain versatility while preventing motor overheating by optimizing air flow for each balloon type.
Solution Approach 2:
The patent incorporates a movable inflation nozzle that can dynamically adjust its position and opening size based on the balloon type. The nozzle can be positioned to provide different degrees of restriction, allowing it to fit various balloon neck sizes while maintaining adequate air flow to prevent motor overheating, thus achieving both versatility and thermal management.
4Productivity
If continuous operation is performed to meet high demand, then productivity increases, but motor temperature rises causing balloon deflation
Solution Approach 1:
The patent segments the air flow into separate working air and motor cooling air paths, allowing continuous operation without temperature buildup. The motor cooling air path continuously removes heat from the motor, enabling sustained high productivity while maintaining balloon pressure stability and preventing deflation caused by warm air.
Solution Approach 2:
The patent establishes continuous motor cooling through a dedicated air path that operates continuously during balloon inflation. This continuous cooling action prevents temperature accumulation, allowing the system to operate continuously at high productivity levels without causing balloon deflation, thus maintaining both productivity and reliability.

AI summary
A balloon inflator includes a nozzle adaptor configured to fit over an outlet of an inflation nozzle. A nozzle receipt is provided by the balloon inflator housing to selectively receive the nozzle adaptor and a switch is provided at the nozzle receipt. The nozzle adaptor is adapted to trigger the switch when received at the nozzle receipt. The switch controls the power supplied to the motor, such that different motor operating parameters are realized when the switch is triggered and when the switch is not triggered. In a particular embodiment, the nozzle adaptor includes vent channels that exhaust a portion of the air to the atmosphere when a balloon is fitted over the alternate outlet.
