Multi-Locking Closure System for Exercise Bag Sand Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise bag systems suffer from closure failure due to sand and debris embedding in the closure system, leading to instability and discomfort during use, and they often lack durability and adequate particle retention.
Innovation Solution
An exercise bag system with a multi-locking closure system, comprising a first closure system inside the bag, a second closure system on the outer surface, and a third closure system on a foldable panel, which ensures secure sealing and prevents sand or particles from escaping or embedding in the closure mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single closure system is used in conventional exercise bags, then the device complexity is low, but the reliability of sand retention deteriorates due to closure failure from embedded sand and debris
Solution Approach 1:
The closure system is divided into three separate closure systems (first, second, and third closure systems) positioned at different locations on the bag opening. Each closure system independently secures the opening, so that failure of one does not compromise the entire sealing function. This segmentation directly resolves the contradiction by improving reliability through redundancy while maintaining manageable complexity through modular design.
Solution Approach 2:
The closure systems are arranged in a nested configuration where the first closure system is inside the bag, the second closure system is on the outer surface, and the third closure system is on a foldable panel. This nesting allows multiple closure mechanisms to be integrated in a compact manner, improving reliability without excessive increase in overall device complexity.
2Duration of action of stationary object
If conventional closure systems are used, then the device complexity is low, but the durability deteriorates due to sand embedding in the closure mechanisms
Solution Approach 1:
The closure systems are positioned and configured to prevent sand and debris from embedding in the closure mechanisms. The first closure system is placed inside the bag away from the opening edge, the second closure system is on the outer surface, and the third closure system is on a foldable panel. This extraction of closure elements from the sand-prone opening area directly improves durability by eliminating the embedding problem while maintaining reasonable complexity through strategic positioning.
Solution Approach 2:
The multi-locking closure system is designed to engage in a specific sequence, with the first closure system engaging first, followed by the second and third closure systems. This preliminary engagement sequence ensures that the bag opening is progressively secured before sand can escape or embed in the closure mechanisms, thereby improving durability through preventive action.
3Stability of the object's composition
If a simple closure system is used, then the ease of operation is high, but the stability deteriorates due to closure failure during exercise movements
Solution Approach 1:
The closure system is segmented into three independent closure systems that can be operated separately. Each closure system can be engaged or disengaged independently, allowing the user to secure or open the bag in stages. This segmentation improves stability by ensuring that even if one closure fails during exercise movements, the other closures maintain bag integrity, while ease of operation is preserved through the ability to engage closures sequentially.
Solution Approach 2:
The closure systems are designed with movable components that allow for dynamic engagement and disengagement. The foldable panel with the third closure system can be dynamically adjusted, and the multiple closure points allow the bag to adapt to various exercise movements while maintaining stability. This dynamic design improves stability during exercise while keeping operation easy through flexible engagement mechanisms.

AI summary
The present disclosure is directed to an exercise bag system for carrying a mass of sand or other granular particles that includes a bag article, a first closure system, a second closure system and a third closure system. The first closure system is at the top and proximate the opening and inside the bag article. The second closure system is at the top and located entirely on the outer surface of the first side panel. The third closure system is at the top and on a foldable panel coupled to the first side panel, such that when the first closure system and the second closure system are engaged, the third closure system is configured to be engaged to seal the bag article.
