Adjustable Holster With Interlocking Straps For Device Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holsters for personal electronic devices are typically of fixed sizes, failing to securely accommodate devices of varying sizes and often expose them to damage from bumps or falls, and require a belt loop for attachment, which can be inconvenient.
Innovation Solution
An adjustable holster with interlocking horizontal and vertical straps using a hook and loop fastening system, allowing for customizable fit and secure attachment to a belt or waistband without a belt loop, featuring a solid base with recessed channels for adhesive tape to prevent strap detachment and a friction pad system for adjustable grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size holster is used, then the manufacturing process is simplified, but it cannot accommodate devices of different sizes securely
Solution Approach 1:
The holster is divided into separate components: a base and adjustable straps. The straps can be independently adjusted and positioned to accommodate devices of various sizes, while the base provides structural support. This segmentation allows customization without redesigning the entire holster structure.
Solution Approach 2:
The holster incorporates adjustable straps with buckles that allow dynamic reconfiguration of the holster's dimensions. Users can modify the strap lengths and positions to fit different device sizes, transforming a static structure into a dynamically adaptable one.
2Ease of manufacture
If permanently fixed straps are used to form the holster body, then the structure is simplified, but it requires additional manufacturing steps and cost
Solution Approach 1:
The holster is divided into separate components: a base and adjustable straps. The straps can be independently adjusted and positioned to accommodate devices of various sizes, while the base provides structural support. This segmentation allows customization without redesigning the entire holster structure.
Solution Approach 2:
The holster incorporates adjustable straps with buckles that allow dynamic reconfiguration of the holster's dimensions. Users can modify the strap lengths and positions to fit different device sizes, transforming a static structure into a dynamically adaptable one.
3Reliability
If a belt loop is used for attachment, then the holster can be suspended from a belt, but it requires removing pants belt loops for installation and removal
Solution Approach 1:
The traditional belt loop attachment mechanism is removed entirely. Instead, the holster uses a friction-based grip system with adhesive tape and friction pads that attach directly to the belt or waistband material, eliminating the need for belt loops and simplifying installation and removal.
Solution Approach 2:
The mechanical belt loop system is replaced with a friction-based adhesive system. The combination of adhesive tape and friction pads creates a reliable attachment that can be easily applied and removed without mechanical fasteners or belt loops.
4Strength
If the holster has no rigid base or backing, then the structure is simplified and lighter, but the device edges are vulnerable to damage
Solution Approach 1:
The holster combines a rigid base material (such as plastic or hard polymer) with flexible strap materials. This composite construction provides edge protection for devices while keeping the overall weight low through the use of lightweight rigid materials and minimal structural elements.
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 adjustable holster securely fits devices of different sizes, reduces exposure to damage, and allows easy attachment to a belt or waistband without a loop, providing a strong, lightweight, and customizable solution for various device sizes.
Implementation Method 1
All straps having a webbing having one side, or surface, covered by the hook portion or elements of a hook and loop fastening system and the other, or opposing, side or surface, covered by the loop elements of a hook and loop fastening system
Implementation Method 2
a solid base with recessed channels for adhesive tape to prevent strap detachment
Implementation Method 3
a friction pad system for adjustable grip

AI summary
The holster includes a solid basically flat rectilinear shape. In one embodiment, a horizontal slot through the thickness of the base receives a strap that is wrapped around the portable device, while a second strap, vertically oriented, is fixed in a keyway in the bottom of the base and threaded through a vertical slot in the thickness of the base and is brought upward over the horizontal strap. In a second embodiment a pair of horizontal straps are set in keyways and are wrapped around a portion of the portable device, holding it in place. All straps having a webbing having one side covered by the hook portion of a hook and loop fastening system and the other side covered by the loop elements of a hook and loop fastening system, allowing opposite sides, or faces, of any single strap to be fastened to itself.
