Standing Lamp Clamp Assembly to Prevent Fastener Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing standing lamps face issues with screws loosening and falling out, making it inconvenient to adjust the lamp height due to inadequate fixation mechanisms.
Innovation Solution
A standing lamp connection apparatus featuring a fastener with a rotary knob, pressing plate, and threaded design that prevents screws from detaching by blocking the pressing plate's movement when adjusted, ensuring firm fixation and preventing accidental detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the connecting base to the stand column, then the position can be fixed, but the screws easily come out and fall when loosened
Solution Approach 1:
The fastener is divided into multiple functional segments: a threaded portion for engagement with the threaded hole, a pressing plate portion for contacting the stand column, and a rotary knob portion for operation. This segmentation allows each part to perform its specific function optimally while working together as an integrated system that prevents detachment.
Solution Approach 2:
The pressing plate acts as an intermediary element between the fastener and the stand column. It transfers the clamping force from the threaded fastener to the stand column surface, providing stable fixation while the oversized design prevents the fastener from detaching by blocking its movement path.
2Reliability
If the pressing plate radial size is made larger than the sliding hole diameter, then the fastener cannot detach, but the structure becomes more complex
Solution Approach 1:
The pressing plate serves multiple functions simultaneously: it provides the clamping surface against the stand column, acts as a stopper to prevent fastener detachment, and guides the fastener movement within the sliding hole. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in structural complexity.
Solution Approach 2:
The anti-detachment function is merged into the pressing plate design itself rather than being a separate component. The pressing plate is integrated with the fastener body, combining the clamping and anti-detachment functions into a single unified structure, which minimizes overall device complexity.
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 apparatus provides a secure and user-friendly mechanism that prevents screws from falling off during adjustment, enhancing the overall user experience by reducing inconvenience and improving structural stability.
Implementation Method 1
an external thread in cooperation with the threaded hole is disposed on an outer peripheral wall of the fastener
Implementation Method 2
the pressing plate can press firmly against the stand column
Implementation Method 3
a radial size of the pressing plate is greater than a diameter of the sliding hole, and the pressing plate is able to press firmly against the stand column

AI summary
A standing lamp connection apparatus is provided, including a connecting base and a fastener. The connecting base defines a vertical through hole for a stand column to pass through, and a threaded hole perpendicular to the through hole in a side face of the connecting base. A sliding hole in fluid communication with the through hole is formed in a bottom wall of the threaded hole. The fastener is inserted into the threaded hole, an external thread is disposed on an outer peripheral wall of the fastener, an end of the fastener stretches out of the threaded hole and is provided with a rotary knob while the other end stretches out of the sliding hole and is provided with a pressing plate, a radial size of the pressing plate is greater than a diameter of the sliding hole, and the pressing plate can press firmly against the stand column.
