Adjustable Rope Penetration Unit for Fan Garment Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fan-equipped garments face a challenge in maintaining an effective cooling effect when used with a full harness type safety belt, as the air flow passage is closed when the belt is attached to the outside of the garment body, and the rope penetration unit's opening section needs to be large enough to allow a hook to pass through, leading to excessive air leakage if reduced for better closure.
Innovation Solution
An opening section adjustment mechanism that allows for the adjustment of the opening area of the rope penetration unit while maintaining a slight opening around the rope, even when the opening area is minimized, utilizing a contraction unit and contraction control mechanism to ensure the inner circumference of the opening section remains larger than the outer circumference of the rope, facilitating air outlet functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the opening section of the rope penetration unit is made large enough to allow a hook to pass through, then the safety belt can be properly attached, but air leakage increases and cooling effect is reduced
Solution Approach 1:
The opening section is made adjustable rather than fixed. The contraction unit allows the opening area to be dynamically changed between a first state (larger opening for safety belt attachment) and a second state (smaller opening to reduce air leakage). This dynamic adjustment resolves the contradiction by allowing the system to optimize for different functions at different times.
Solution Approach 2:
The area parameter of the opening section is made variable through the contraction unit mechanism. By changing the area parameter between two states, the system can accommodate both the requirement for large opening (safety belt attachment) and small opening (cooling efficiency) without compromise.
2Loss of energy
If the opening section is reduced to improve closure and reduce air leakage, then cooling effect improves, but the hook cannot pass through the opening section
Solution Approach 1:
The opening section transitions from a static small opening to a dynamic opening that can expand when needed. The contraction unit enables the opening to be small during cooling operation and temporarily enlarged when safety belt attachment is required, resolving the contradiction between closure and adaptability.
Solution Approach 2:
The contraction unit is pre-configured to allow easy expansion of the opening section when needed. The mechanism is designed so that the opening can be quickly enlarged to accommodate the hook before attachment, then returned to closed state, allowing safety belt attachment without permanently compromising cooling effect.
3Loss of energy
If an air seal is used to close the opening section, then air leakage is reduced, but the opening section cannot be used as an air outlet
Solution Approach 1:
The opening section's state is made dynamic rather than permanently sealed. The contraction unit allows the opening to be closed (sealed) during normal operation to prevent air leakage, and temporarily opened to function as an air outlet when needed, providing both functions without compromise.
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 mechanism allows for improved cooling efficiency by maintaining a suitable air outlet area around the rope penetration unit, reducing air leakage and ensuring effective air discharge through the collar and sleeve openings, thus enhancing the overall cooling performance of the fan-equipped garment.
Implementation Method 1
a contraction unit that contracts a rim of the opening section
Implementation Method 2
Pressure of the air taken in automatically creates an air flow passage between the garment body and a wearer's body
Implementation Method 3
The taken-in air evaporates sweat on the wearer's body while flowing through the air flow passage between the garment body and the wearer's body or underwear
Implementation Method 4
The heat of vaporization generated by evaporating sweat cools the body

AI summary
An opening section adjustment mechanism adjusts an opening area of an opening section through which a rope is passed. The opening section adjustment mechanism includes an opening creation mechanism that leaves an opening section around the rope passed through the opening section even when the opening area of the opening section is adjusted to the minimum.
