One-Piece Electronic Ballast Casing with Pivoting End Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic ballast casings are structurally complex and costly due to their multi-piece configuration, requiring lengthy assembly times and increasing overall product costs.
Innovation Solution
A one-piece casing with integrally formed top, bottom, side, and end walls that pivot to enclose a PCB assembly, utilizing snap-fitting mechanisms for assembly and positioning, eliminating the need for separate mechanical components and filling materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a two-piece or multi-piece casing configuration is used, then the casing can provide structural support and enclosure, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple casing components (base portion, lid portion, support structures, insulation plates, and filling portions) into a single integrated casing body. This merging eliminates the need for separate mechanical components and assembly operations, thereby reducing device complexity while maintaining the required structural support function.
2Strength
If a two-piece or multi-piece casing configuration is used, then the casing can provide structural support and enclosure, but the manufacturing cost increases
Solution Approach 1:
The patent integrates multiple functions and components into a single casing body that can be manufactured as one piece. This eliminates the need for separate manufacturing processes for base portions, lid portions, support structures, and insulation plates, thereby reducing manufacturing cost while maintaining structural support capability.
3Strength
If a two-piece or multi-piece casing configuration is used, then the casing can provide structural support and enclosure, but the assembly time increases
Solution Approach 1:
The patent consolidates multiple casing components into a single integrated structure, eliminating the need for assembly operations between base portions, lid portions, support structures, and insulation plates. This merging directly reduces assembly time and improves productivity while maintaining the required structural support.
4Device complexity
If a one-piece casing configuration is used, then the device complexity and manufacturing cost are reduced, but the ease of repair and component replacement becomes more difficult
Solution Approach 1:
The patent incorporates a removable lid portion that can be separated from the main casing body. This segmentation allows easy access to the PCB assembly and other internal components for repair and replacement, while the rest of the casing remains as an integrated one-piece structure, thus balancing ease of repair with reduced device complexity.

AI summary
A casing for electronic ballast, in which a PCB assembly is received, may include: a top wall; a bottom wall opposite to the top wall; two opposite side walls extending integrally between the top wall and bottom wall; and two opposite end walls extending integrally from the top wall, wherein the top wall, bottom wall, side walls and end walls are formed integrally, the top wall, bottom wall and side walls define openings at both ends of the casing in a lengthwise direction of the casing, the end walls are arranged to be pivotable relative to the top wall so as to close the openings formed by the top wall, bottom wall and side walls.
