Rail Fastener With Cage Holder For Adjustable Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fasteners for mounting rails lack securement against unintentional displacement while maintaining ease of movement in the longitudinal direction, particularly under gravity.
Innovation Solution
A fastener design featuring a support and hammer head element with a variable distance connection via a plastic holder, allowing for two locking positions: one for secure clamping and another for easy longitudinal movement, facilitated by a holder that forms a cage-like structure for the hammer head element, enabling rotation and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fastener is designed to be securely clamped against unintentional displacement, then stability and reliability are improved, but ease of movement and adjustability deteriorates
Solution Approach 1:
The holder is designed with two distinct locking positions that allow the hammer head element to be either securely clamped or freely movable. The resilient spring arm provides a dynamic locking mechanism that automatically secures the element in either position, enabling the fastener to transition between stable and movable states as needed
2Adaptability or versatility
If the holder structure is made complex to provide two locking positions, then functionality and versatility are improved, but device complexity increases
Solution Approach 1:
The resilient spring arm performs multiple functions simultaneously: it acts as a locking mechanism, a positioning element, and a return spring. By combining these functions into a single component, the design achieves two locking positions without proportionally increasing complexity, as the spring arm integrates several mechanical functions that would otherwise require separate components
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 fastener provides secure clamping against unintentional displacement while allowing intentional movement and adjustment, ensuring stability against gravity and enabling easy positioning and height adjustment of attached objects like pipe clamps.
Implementation Method 1
the holder (7) has a resilient spring arm (18), in particular with locking lugs (19), radially to the axis (10) of the fastening thread (9)
Implementation Method 2
