Accessory Mounting Track Interlocks for Secure Multi-Direction Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accessory mounting tracks face challenges in providing quick and easy attachment and removal of devices while preventing overtightening and loosening, which can lead to device failure due to reliance on static friction and varying grip strengths.
Innovation Solution
Incorporating physical interlocks on accessory devices that mate with slots or interlocking features on the mounting track, allowing for secure attachment in multiple directions without relying on frictional forces, thereby preventing movement and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static friction is leveraged to hold the device in a desired position, then the device can be secured without additional locking mechanisms, but the device may be overtightened or loosened to the point of failure
Solution Approach 1:
The track is segmented with discrete locking positions featuring interlocking elements (protrusions and recesses) that divide the continuous mounting surface into specific attachment points. This segmentation prevents continuous movement and locking at any position, restricting attachment only to predetermined safe positions where overtightening is prevented by the mechanical interlock geometry.
Solution Approach 2:
The interlocking elements automatically engage when the device is positioned on the track and secured, providing self-locking functionality without requiring additional active locking mechanisms or user intervention. The protrusions and recesses mate together to create a passive mechanical lock that prevents both overtightening and loosening.
2Reliability
If rubber washers or textured surfaces are used to increase static friction, then the device can be held more securely against movement, but the device becomes harder to remove or may fail to secure adequately
Solution Approach 1:
Instead of increasing friction to prevent movement (conventional approach), the invention inverts the approach by using mechanical interlocking elements that prevent movement through geometric constraint rather than friction. The protrusions and recesses create a mechanical lock that secures the device without relying on frictional forces, making removal as easy as alignment and engagement.
3Reliability
If varying degrees of grip, strength, texture and material are used to secure the device, then the device can be adequately secured to the track, but this results in difficulty in removing the device
Solution Approach 1:
The invention changes the fundamental parameter of attachment from friction-based (requiring varying grip strength and material properties) to geometry-based mechanical interlocking. The protrusions and recesses are designed with specific dimensional parameters that ensure proper engagement, allowing secure attachment through alignment rather than force, and easy removal by disengaging the geometric interlock.

Function Achieved in This Case
Ensures secure and easy attachment and removal of devices with reduced risk of overtightening or loosening, suitable for users with gripping issues, and provides stable positioning without relying on frictional engagement.
Implementation Method 1
the interlocks mate with the interlocking features, resulting in physical interference, to prevent movement of the accessory device along the accessory mounting track
Implementation Method 2
the accessory device is prevented from moving along the accessory mounting track when sufficient frictional forces are applied

AI summary
An accessory device is provided with one or more physical interlocks for mating with a slot provided along an accessory mounting track, or alternatively, with discrete physical mating interlocking features provided along an accessory mounting track, such as along opposing sides of the slot. In this way, the accessory device can be mounted along the slot in a lengthwise direction of the accessory mounting track or perpendicularly or transversely to the lengthwise direction of the accessory mounting track. When mounting in a lengthwise direction of the accessory mounting track, the accessory device is prevented from moving along the accessory mounting track when sufficient frictional forces are applied. When mounting perpendicularly or transversely to the lengthwise direction of the accessory mounting track, the interlocks mate with the interlocking features to prevent movement of the accessory device along the accessory mounting track.
