U-Shaped Carrier With Adjusting Rod For Blind Component Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carriers for blind components allow vertical displacement and outward leg movement, leading to instability and potential falling of the blind component.
Innovation Solution
A carrier design featuring a U-shaped housing with an adjusting rod and V-shaped receptacles, where the adjusting rod rotates to press the blind component down into the receptacles, preventing vertical adjustment and outward leg movement, and an eccentric lever mechanism ensures secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blind component is clipped into the carrier using resilient legs with receptacles, then the blind component can be easily installed, but the blind component can be displaced vertically and the legs can be pushed outwards causing instability
Solution Approach 1:
The adjusting rod is rotatably mounted on the carrier, allowing it to dynamically adjust and apply continuous downward force on the blind component. This dynamic mechanism ensures the blind component remains firmly pressed into the receptacles during operation, preventing vertical displacement while maintaining ease of installation through the resilient leg design.
Solution Approach 2:
The adjusting device changes the force parameter applied to the blind component by rotating the adjusting rod. This generates a pressing force that continuously pushes the blind component down into the receptacles, eliminating vertical play and preventing the legs from being pushed outwards, thus improving stability without compromising installation ease.
2Reliability
If the adjusting rod is rotatably mounted to press the blind component down, then vertical displacement is prevented, but the device complexity increases
Solution Approach 1:
The adjusting rod is designed to be rotatably mounted on the carrier base and automatically applies downward force through its rotation. The mechanism serves itself by using the rotational motion to generate the necessary pressing force without requiring additional actuators or complex control systems, thus achieving vertical positioning stability with minimal added complexity.
Solution Approach 2:
The adjusting rod serves multiple functions: it applies downward force to prevent vertical displacement, maintains continuous contact with the blind component through its rotational capability, and integrates with the existing carrier structure. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving reliable vertical positioning.
3Reliability
If the receptacles are V-shaped to wedge the blind component, then outward leg movement is prevented, but manufacturing precision requirements increase
Solution Approach 1:
The V-shaped receptacles utilize the geometric parameter of the angle to create a wedging effect. By designing the receptacles with inwardly angled sections, the structure naturally prevents outward leg movement through the mechanical advantage of the wedge shape, reducing the need for extremely high manufacturing precision while still achieving reliable prevention of leg deflection.
Solution Approach 2:
The lower edge sections of the blind component include inwardly rounded sections that complement the V-shaped receptacles. This curved geometry allows the components to be pressed or wedged into each other in a resilient manner, distributing forces evenly and reducing stress concentration points, thereby achieving reliable hold with moderate manufacturing precision.
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 carrier reliably holds the blind component in place without vertical play or outward leg deflection, enhancing stability and ease of installation and removal.
Implementation Method 1
the adjusting rod is designed to apply a force to the blind component in such a way that the blind component is forced at least in sections into the mounts of the carrier
Implementation Method 2
the adjusting device comprises an adjusting rod, which contains a rotary shaft, which is rotatably mounted on the carrier
Implementation Method 3
the receptacles are V-shaped. For this purpose, the distal ends of the limbs can be angled inwards or towards one another in such a way that the angled sections are in a V-shape relative to the limbs. The lower edge sections of the blind component can thus be wedged into the receptacles.
Implementation Method 4
the carrier being U-shaped with a base and two limbs angled resiliently therefrom, the limbs each being provided with a receptacle at the distal end

AI summary
A support (10) for attaching a blind component (12) to a structure is U-shaped with a base (14) and two legs (16', 16") angled elastically from it. The legs (16', 16") are each provided at their distal end with a receptacle (18', 18"), the receptacles (18', 18") being designed to engage the blind component (12) received in the support (10). The support (10) further comprises an adjustment device designed to apply a force to the blind component (12) such that the blind component (12) is forced, at least partially, into the receptacles (18', 18") of the support (10).
