Solution Overview

Problem

Conventional mounting devices for flashlights or other devices on hats or helmets lack flexibility in positioning, often result in insecure attachment, and can catch or snag external objects, limiting their usability and safety.

Innovation Solution

A mounting device with a base, a movable plate biased by a spring, and an adjustable bracket that allows for secure attachment and rotation of objects, featuring a non-circular cavity and periphery to prevent rotation and ensure detented mounting, reducing the likelihood of snagging or tangling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional mounting devices use rubber or elastic bands, then the mounting is simple and secure, but the positioning flexibility and range of orientations are limited

Engineering Contradiction:
Improvemounting simplicityVSAvoidpositioning flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The mounting device is divided into separate functional components: a base unit with spring mechanism and a detachable bracket system. This segmentation allows the base to provide secure attachment while the bracket provides positioning flexibility, resolving the contradiction between mounting simplicity and positioning flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting device incorporates a spring-loaded plate that provides dynamic adjustment capability. The spring mechanism allows the bracket to be easily positioned and secured at various orientations while maintaining secure attachment, combining the simplicity of elastic mounting with the flexibility of adjustable positioning.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If conventional mounting devices use thumbscrews and articulated joints, then the range of orientations is wide, but the device can become caught, snagged, or tangled with external objects

Engineering Contradiction:
Improverange of orientationsVSAvoidsnagging and entanglement
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and eliminates the problematic articulated joint mechanism from conventional mounting devices. Instead, it uses a spring-loaded plate with a bracket that achieves wide orientation range without protruding moving parts that could snag or tangle with external objects.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Rather than using an articulated joint that extends outward to provide orientation adjustment, the invention inverts the approach by using a spring-loaded bracket system that adjusts orientation through a compact, recessed mechanism that cannot snag on external objects.

Inventive Principle:
Principle #13The other way round (Inversion)

3Device complexity

If certain prior art mounts are used, then the mounting device is compact, but the attachment is insecure and subject to slippage and movement

Engineering Contradiction:
Improvemounting device compactnessVSAvoidattachment security
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The spring-loaded plate acts as a cushioning element that maintains constant contact pressure between the bracket and the mounting surface. This beforehand cushioning ensures secure attachment by compensating for any movement or slippage, providing reliable mounting while keeping the device compact.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The invention changes the pressure parameter dynamically through the spring mechanism. The spring maintains optimal contact pressure to prevent slippage and movement, ensuring secure attachment without requiring a complex, bulky structure.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If mounting devices are designed to hold flashlights of a particular diameter, then the attachment is secure for that specific size, but the adaptability to different objects is limited

Engineering Contradiction:
Improveattachment securityVSAvoidrange of acceptable objects
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The bracket is designed with adjustable geometry and the spring mechanism provides adaptable pressure, allowing the same mounting device to securely attach various objects of different sizes and shapes. This universal design maintains secure attachment across multiple object types without requiring size-specific configurations.

Inventive Principle:
Principle #6Universality (Multi-functionality)
