Lighting Display Device Spring-Assisted Bottle Engagement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting display devices, such as liquid motion lamps, face issues with stability and safety due to unnecessary height requirements and increased manufacturing costs caused by complex engagement and disengagement mechanisms, which lead to potential overturning and space inefficiencies during bottle replacement.
Innovation Solution
A lamp holder structure featuring a frame body with a base, stand, upper and lower fixing elements, and a spring mechanism that allows for easy engagement and disengagement of the transparent bottle, reducing the need for height restrictions and space, while ensuring stability and safety through a spring-assisted assembly and disassembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the second mounted seat has a much longer diameter than the transparent bottle to allow slanting for disengagement, then the transparent bottle can be disengaged, but there is a gap between the bottle and mounted seat that causes overturning and falling
Solution Approach 1:
The engagement mechanism is divided into two independent parts: a lateral engaging groove on the mounted seat and a corresponding engaging protrusion on the bottle. This segmentation allows the bottle to be secured horizontally while maintaining stability, eliminating the need for excessive diameter differences that cause gaps and overturning risks.
2Ease of operation
If the second mounted seat has much higher height than the joint sleeve to accommodate engagement, then the joint sleeve can be engaged, but this results in waste in space and prime cost
Solution Approach 1:
The joint sleeve is extracted from the mounted seat structure, allowing the seat height to be minimized to only what is necessary for the bottle's stability and engagement. The sleeve becomes a separate, removable component that does not dictate the overall height of the mounted seat, thereby reducing wasted space and manufacturing costs.
3Ease of operation
If the joint sleeve and transparent bottle are displaced upwards for disengagement, then the bottle can be removed from the first contacting room, but this requires complex movement and additional space
Solution Approach 1:
Instead of requiring upward displacement for disengagement, the design inverts the approach by using a lateral engaging groove and protrusion system. The bottle is engaged by inserting it laterally into the groove, and disengagement is achieved by simply pulling it horizontally outward, eliminating the need for vertical displacement and reducing the required height space.
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 solution enables convenient and safe replacement of the transparent bottle and bulb, reduces manufacturing costs by eliminating space and height constraints, and enhances the stability of the device during use.
Implementation Method 1
a spring disposed inside the upper engaging space, abutting between the top surface of the assembling element and the transparent bottle for the transparent bottle to be positioned along the axis perpendicular to the base and for the top surface of the assembling element to fixedly engage the depression surface of the positioning plate

AI summary
An improved structure of a lighting display device includes a lower fixing element, an upper fixing element, a projection device, a transparent bottle, and an assembling element. The projection device is disposed inside the lower fixing element and the transparent bottle is disposed thereon and fixed by a positioning annulus on an inner surface of the lower fixing element. The assembling element has an upper engaging space to be mounted on the transparent bottle and a top surface for a depression surface under a positioning plate of the upper fixing element to be engaged and fixed thereon. A spring is further disposed between the upper engaging space and the transparent bottle. Thereby the transparent bottle is able to display attractive visual effects by lighting projection and to be easily engaged and disengaged.
