Split Waterproof Chassis for Easier Stage Lamp Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproof stage light fixtures require complex maintenance procedures, necessitating separation of the base from the support arm to access the interior, complicating maintenance and limiting design flexibility.
Innovation Solution
A waterproof base design featuring a split upper cover and integral bottom frame, with spliced cover bodies and integrated oil seals, allowing maintenance without disassembling other components, and utilizing multiple sealing strips for enhanced waterproof performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base is designed as a closed cylinder body with front and rear plates to achieve waterproof effect, then waterproof performance is improved, but maintenance becomes difficult requiring complete separation of the base with the support arm
Solution Approach 1:
The base is segmented into a removable upper cover and a lower body portion. The upper cover can be detached from the lower body to provide access to internal components for maintenance, while the lower body remains connected to the support arm. This segmentation allows maintenance without complete disassembly while preserving the waterproof sealed structure when assembled.
2Reliability
If the base is designed as a closed cylinder body with front and rear plates, then waterproof effect is achieved, but maintenance requires complicated procedures and complete separation
Solution Approach 1:
The base structure is divided into an upper cover and lower body that can be easily separated. This simple two-part segmentation reduces maintenance procedure complexity compared to the prior art requiring complete disassembly, while maintaining the sealed waterproof structure when assembled.
Solution Approach 2:
The upper cover is extracted as a separate removable component from the base structure. This allows access to internal components for maintenance without affecting the lower body's connection to the support arm, simplifying the maintenance procedure while preserving waterproof integrity.
3Ease of repair
If the upper cover is divided into first and second cover bodies spliced together to form pivoting hole, then maintenance accessibility is improved, but sealing complexity increases
Solution Approach 1:
The upper cover is segmented into first and second cover bodies that are spliced together to form the pivoting hole. This segmentation provides access to internal components for maintenance while the sealing structures (sealing strips and oil seals) manage the complexity of maintaining waterproof integrity across the spliced joints.
Solution Approach 2:
Sealing strips made of flexible material are used at the spliced portions of the cover bodies and at the interface with the lower body. These flexible sealing elements accommodate the spliced construction while maintaining waterproof integrity, managing the sealing complexity introduced by the segmented upper cover.
4Productivity
If the bottom frame is integrally formed by die-casting, then manufacturing speed and strength are improved, but design flexibility for modeling is reduced
Solution Approach 1:
The base is divided into an integrally formed lower body (by die-casting) and a separately formed upper cover. This segmentation allows the lower body to be manufactured efficiently by die-casting for high productivity and strength, while the upper cover can be separately manufactured with various designs to provide modeling flexibility and adaptability.

AI summary
The present invention discloses a waterproof base convenient to maintain and a stage light fixture having the same. The waterproof base convenient to maintain includes a bottom frame which is integrally die-cast formed, and an upper cover with a pivoting hole covering the bottom frame. The upper cover includes a first cover body and a second cover body which are spliced to each other. The pivoting hole is formed by jointly splicing the first cover body and the second cover body, and an oil seal for sealing the outer side of a pivoting shaft penetrated the pivoting hole is disposed at the pivoting hole. The oil seal is mounted and fixed by a mounting plate. A first sealing strip seals the first cover body, the second cover body and the mounting plate with respect to each other, the first cover body and the second cover body abut against the bottom frame, and second sealing strips are disposed at abutting positions. According to the present invention, the upper cover is divided into the first cover body and the second cover body, and the pivoting hole is formed by jointly splicing the first cover body and the second cover body, so that it is possible to remove the upper cover from the bottom frame without disassembling other components to conduct convenient and quick maintenance on the interior of the waterproof base.
