Hip Pack Belt Track With Braking for Easy Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable pack systems, such as hip packs, require complete removal or rotation for access, limiting their usability in various situations due to fixed positioning.
Innovation Solution
A hip pack system with a track system and connection system that allows the pack to move along a predetermined path, utilizing a braking system with one-way cam units for controlled movement, enabling easy repositioning without removing the belt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pack is fixed in place along the belt, then the belt structure remains simple, but the pack cannot be accessed without complete removal or rotation
Solution Approach 1:
The connection system transitions from a fixed attachment to a dynamic movable connection. The pack can slide along the belt's length via a track system with a T-shaped element that moves within a sleeve, allowing the pack to be repositioned and accessed without removing the entire belt assembly.
Solution Approach 2:
The connection system is divided into separate functional components: a T-shaped element for movement, a sleeve for guidance, and a braking system for positioning. This segmentation allows each component to perform its specific function while maintaining overall system simplicity.
2Ease of operation
If the pack can move freely along the belt, then pack accessibility is improved, but uncontrolled movement becomes a problem
Solution Approach 1:
The braking system automatically engages when the pack reaches the desired position or when movement stops. The cam units self-lock into the track system without requiring active control, providing automatic positioning and stability while maintaining ease of repositioning.
Solution Approach 2:
The braking system changes the friction parameter between the pack and belt. When braking is engaged, high friction prevents movement; when released, low friction allows smooth sliding. This parameter change enables both stable positioning and easy repositioning.
3Stability of the object's composition
If a braking system is added to control pack movement, then position stability is improved, but the connection system becomes more complex
Solution Approach 1:
The braking function is extracted as a separate, simple mechanism from the main connection system. The cam units and handles are distinct components that can be independently analyzed and manufactured, reducing overall system complexity while providing effective positioning control.
4Reliability
If the pack is securely attached to the belt, then reliability is improved, but ease of repositioning deteriorates
Solution Approach 1:
The T-shaped element and sleeve act as intermediary components between the pack and belt. They provide a reliable connection through precise geometric fitting while allowing controlled sliding motion, thus mediating between the conflicting requirements of secure attachment and easy repositioning.
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
Enables flexible and convenient access to the pack by allowing movement along the track system, enhancing usability and comfort by eliminating the need to loosen or remove the belt.
Implementation Method 1
The braking system can include a first cam unit on a first side of the pack and a second cam unit on a second side of the pack. The first cam unit can be coupled to a first handle on the second side of the pack and the second cam unit can be coupled to a second handle on the first side of the pack.
