Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holsters for communications devices lack effective securing mechanisms and materials that provide both protection from fire and water, while also being user-friendly and adaptable for various devices.
Innovation Solution
A holster design featuring a backing with a rigid plate, a fire-resistant interior liner, and a water-resistant exterior, along with a strap assembly and securing elements like hook and loop fasteners, which collectively create a secure and adaptable cavity for communications devices, allowing for easy attachment to belts or straps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a holster uses traditional securing mechanisms, then the device is held in place, but the securing mechanism lacks reliability and effectiveness
Solution Approach 1:
The holster is divided into distinct functional segments: a pouch for device insertion, a backing with rigid plate for structural support, a strap assembly for attachment, and a liner for protection. Each segment performs a specific function, improving overall reliability without requiring a monolithic complex structure.
Solution Approach 2:
Multiple securing functions are merged into the strap assembly, which combines the strap, buckle, and adjustment mechanisms into a single integrated component that provides both attachment and securing functions, reducing the number of separate parts needed.
2Object-affected harmful factors
If the holster uses standard materials, then manufacturing is simple, but the holster lacks fire and water resistance
Solution Approach 1:
The holster employs composite material construction with a rigid plate (metal or hard plastic) for structural integrity, a water-resistant outer material for protection, and a fire-resistant liner for thermal protection. This multi-material approach provides fire and water resistance while maintaining manufacturability through standard material joining techniques.
Solution Approach 2:
Different regions of the holster use different materials optimized for their specific functions: the outer shell uses water-resistant material for environmental protection, the liner uses fire-resistant material for thermal protection, and the rigid plate provides structural support. This localized material selection achieves protection without requiring the entire holster to be made from specialized difficult-to-manufacture materials.
3Reliability
If the holster is designed for specific devices, then security is improved, but adaptability for various devices is reduced
Solution Approach 1:
The holster cavity is designed with universal dimensions and features that can accommodate multiple types of communications devices. The adjustable strap assembly and modular pouch configuration allow the same holster structure to securely hold different device sizes and shapes, providing both security and adaptability.
Solution Approach 2:
The holster incorporates adjustable and reconfigurable elements such as the adjustable strap length, removable pouch, and flexible liner that can be adapted to different device configurations. This dynamic design allows the holster to maintain secure fit across various device types without requiring multiple specialized holsters.
4Reliability
If the holster uses complex securing elements, then device security is improved, but ease of operation is reduced
Solution Approach 1:
The strap assembly incorporates a self-buckling mechanism where the strap secures itself through an interlocking buckle system that requires simple insertion and engagement actions. The hook and loop fasteners on the pouch provide automatic securing when the device is inserted, eliminating the need for complex manual fastening operations while maintaining reliable device retention.

AI summary
A holster includes a backing, a pouch, a strap assembly, and a liner. The pouch includes a first securing element disposed along a front wall thereof. The pouch is coupled to the backing to cooperatively define a cavity configured to receive a communications device. The strap assembly is coupled to the backing and selectively couplable with the pouch. The strap assembly includes a cord, a handle, and a second securing element. The handle is coupled to the cord along a portion of the cord opposite the backing. The second securing element is disposed along a rear surfaces of the handle. The second securing element is couplable to the first securing element. The liner includes a fire resistant material and/or a fire retardant material and is disposed within the cavity along at least one of an interior surface of the backing and an interior surface of the pouch.
