Adjustable Shoulder Holster with Modular Shell and Keyhole Harness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional holsters lack versatility and comfort for extended wear, particularly when carrying a handgun under clothing, as they often do not allow for adjustable carry angles and secure, tool-free interchangeability of holster shells and straps.
Innovation Solution
An adjustable shoulder holster assembly with modular holster shells and quick-disconnect strap clips that allow for various carry angles and easy interchange of holster shells without tools, using a harness with straps that can be adjusted and secured via strap clips and keyhole mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional holster is used to carry a handgun under clothing, then the handgun is protected and retained, but the holster lacks versatility for different carry angles and locations
Solution Approach 1:
The holster is divided into a shell and a backer as separate components that can be attached and detached. The backer includes multiple attachment locations with keyhole mechanisms, allowing the shell to be positioned at various angles and locations while maintaining a relatively simple individual structure for each component.
Solution Approach 2:
The backer is designed with multiple attachment locations that can accommodate different shell orientations and positions. This universal attachment system allows a single backer to support various carry configurations (shoulder, waist, ankle, etc.) and different implement types, increasing versatility without requiring multiple specialized holsters.
2Reliability
If a rigid holster is used to allow repeated drawing and re-holstering, then the handgun can be accessed reliably, but the holster becomes uncomfortable for extended wear
Solution Approach 1:
The holster system separates the rigid shell (which provides reliable draw and re-holstering) from the backer (which can include flexible or comfortable elements for extended wear). This segmentation allows each component to be optimized for its specific function while working together as a system.
Solution Approach 2:
Different parts of the holster system have different properties: the shell is rigid for reliable implement retention and drawing, while the backer can be made with softer, more comfortable materials for areas in contact with the body during extended wear, providing locally optimized characteristics.
3Adaptability or versatility
If a holster provides adequate protection but does not allow for a user's preferred draw position, then the implement is secure, but the holster is not acceptable for use
Solution Approach 1:
The attachment system separates the shell positioning function from the retention function, allowing the shell to be configured at multiple draw positions by attaching to different keyhole locations on the backer, while maintaining secure retention at each position through the same attachment mechanism.
Solution Approach 2:
The keyhole mechanism allows adjustment of the shell's position and orientation parameters (location, angle, height) by attaching to different keyhole locations, enabling users to change draw position without altering the fundamental holster design or requiring multiple specialized holsters.
4Adaptability or versatility
If a holster allows quick interchange of shells and straps, then versatility is improved, but the attachment mechanism becomes more complex
Solution Approach 1:
The attachment mechanism is segmented into standardized components (keyholes on the backer, corresponding attachment features on shells and straps) that enable quick interchange while keeping each individual component relatively simple in design.
Solution Approach 2:
The keyhole attachment mechanism serves multiple functions: it allows quick attachment and detachment, provides adjustable positioning, secures different implement types, and enables configuration changes without requiring complex specialized mechanisms for each function.

AI summary
A shoulder holster assembly is used to support and to carry an implement in a holster. The shoulder holster assembly includes a base or an implement carrier removably coupled to a harness. The harness includes a plurality of length-adjustable straps with strap clips at the ends, configured to engage receivers in the base or the implement carrier.
