Solution Overview

Problem

Existing hydration bladders lack a reliable leak-proof mechanism that allows for easy filling and consumption while maintaining a secure seal, especially when folded or attached to a carrying container.

Innovation Solution

A leak-proof hydration bladder with a top opening, a strap closure mechanism, and a hose for consumption, made from flexible plastic material that maintains a seal when folded and the closure is engaged, utilizing a strap with quick release buckles or other closure means to ensure a leak-proof seal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the bladder is made foldable for compact storage, then portability and storage efficiency are improved, but the risk of leakage increases due to the folding mechanism

Engineering Contradiction:
Improvestorage volumeVSAvoidleak-proof seal
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The bladder is divided into multiple segments or panels that can be folded relative to each other. The closure mechanism is segmented into multiple fastening points along the fold lines, ensuring that each segment maintains a secure seal while allowing the overall structure to be folded compactly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The closure mechanism is designed to be engaged before the bladder is folded or attached to a carrying container. This preliminary sealing action ensures that the opening is secured prior to any folding or attachment, preventing leakage during subsequent handling and storage.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If a secure closure mechanism is used to prevent leakage, then reliability is improved, but the complexity of the device increases

Engineering Contradiction:
Improveleak-proof sealVSAvoidclosure mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The closure mechanism is designed to serve multiple functions: it seals the bladder opening, secures the fold, and provides attachment points for carrying containers. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity while maintaining reliability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The closure mechanism merges the sealing function with the fastening function into a single integrated system. The same mechanism that seals the opening also secures the folded structure, eliminating the need for separate sealing and fastening components.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the bladder is designed for easy filling and consumption, then ease of operation is improved, but the seal reliability may be compromised

Engineering Contradiction:
Improvefilling and consumptionVSAvoidleak-proof seal
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The closure mechanism is engaged before the bladder is folded or attached to a carrying container. This preliminary sealing action ensures that the opening is secured prior to any folding or attachment, preventing leakage during subsequent handling and storage.

Inventive Principle:
Principle #10Preliminary action

4Adaptability or versatility

If the bladder is made from flexible plastic material, then adaptability and comfort are improved, but the structural integrity for maintaining a seal deteriorates

Engineering Contradiction:
ImproveflexibilityVSAvoidseal integrity
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The closure mechanism is designed with localized reinforcement at the seal lines and fold points. These specific areas have enhanced structural properties compared to the rest of the flexible bladder body, allowing the material to remain flexible overall while maintaining seal integrity at critical locations.

Inventive Principle:
Principle #3Local quality

AI summary

Disclosed herein are embodiments for a leak-proof hydration bladder with an improved opening and folding closure mechanism. Embodiments include an opening on a top side of the bladder and a closed bottom side. A strap is attached to a first side of the bladder and extends to a second side opposite. The strap has a closure mechanism that attaches to a second side of the bladder. The bladder includes a hose with access to an inside of the bladder for consumption of its contents. The bladder is made of a plastic material that maintains a substantially leak-proof seal when the bladder is folded from the top and the closure mechanism is closed.
