Balloon with Integrated Stick Insertion Hole for Stable Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing balloons to sticks, such as using a cup or winding a mounting leg, are cumbersome and require additional operations, especially when displaying multiple balloons at events.
Innovation Solution
A balloon design featuring two joined plastic films with a gas supply valve and chambers that allows for stable fixation to a stick without the need for external cups or winding, using thermal welding and a gas passage that functions as a check valve to secure the stick in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cup-based anchoring tool is used to fix the balloon to a stick, then the balloon can be firmly supported without wobbling or swinging, but the operation becomes cumbersome when fixing multiple balloons
Solution Approach 1:
The invention merges the balloon body with the anchoring function by integrating a stick insertion hole directly into the balloon structure. The balloon is formed by joining two films with a stick insertion hole, allowing the stick to pass through and be anchored directly to the balloon body, eliminating the need for separate cup-based anchoring tools and simplifying the attachment operation while maintaining stability.
Solution Approach 2:
The invention extracts the anchoring function from the separate cup-based system and integrates it directly into the balloon structure. By incorporating the stick insertion hole into the balloon body itself, the anchoring capability is extracted from the external cup accessory and embedded within the balloon, enabling direct and simple stick attachment.
2Reliability
If a cup-based anchoring tool is used to fix the balloon to a stick, then the balloon can be firmly supported without wobbling or swinging, but additional accessories and operations are required
Solution Approach 1:
The invention merges the balloon body with the anchoring function by integrating a stick insertion hole directly into the balloon structure. The balloon is formed by joining two films with a stick insertion hole, allowing the stick to pass through and be anchored directly to the balloon body, eliminating the need for separate cup-based anchoring tools and simplifying the attachment operation while maintaining stability.
Solution Approach 2:
The balloon structure serves multiple functions: it contains the inflated space while simultaneously providing the anchoring interface through the integrated stick insertion hole. This multi-functional design eliminates the need for separate anchoring accessories, reducing overall system complexity while maintaining reliable fixation capability.
3Reliability
If a film balloon with winding and binding operation is used, then the balloon can be fixed to a retaining bar, but the operation procedure for winding and binding is required
Solution Approach 1:
The invention extracts the anchoring function from the separate cup-based system and integrates it directly into the balloon structure. By incorporating the stick insertion hole into the balloon body itself, the anchoring capability is extracted from the external cup accessory and embedded within the balloon, enabling direct and simple stick attachment.
Solution Approach 2:
Instead of wrapping the balloon around the stick (as in the winding and binding method), the invention inverts the approach by having the stick pass directly through the balloon body via the integrated stick insertion hole. This inversion simplifies the operation from a multi-step winding and binding process to a simple insertion action.
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 balloon can be easily and stably fixed to a stick, eliminating the need for cumbersome cup-based systems and enhancing user convenience and cost-effectiveness by simplifying the attachment process.
Implementation Method 1
the gas supply valve (6) includes a gas passage (61) that extends from a gas inlet (62) positioned on an outer side of the second chamber (16) to an inside of the first chamber (14) through the second chamber (16)
Implementation Method 2
the first film (10) and the second film (12) may be joined together through thermal welding at the peripheral edge (5)

AI summary
A balloon includes two joined plastic films. The balloon includes: a gas supply valve sandwiched between and joined to the first film and the second film; a first chamber receiving air supplied from the gas supply valve for expansion; and a second chamber communicating to the first chamber. The gas supply valve includes a gas passage that extends from a gas inlet positioned on an outer side of the second chamber to an inside of the first chamber through the second chamber. Part of the first film and the second film between the first chamber and the second chamber and between the gas passage and a peripheral edge of the balloon are joined together to form a first weld portion and a second weld portion. The first weld portion is formed on an opposite side of the second weld portion with the gas passage sandwiched therebetween.
