Hollow LED Bulb Structure with Replaceable Electric Poles and Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LED light bulbs are typically cast in one piece, leading to scrapping when the electric pin breaks, and are prone to water accumulation when used outdoors due to their solid structure.
Innovation Solution
A hollow light bulb structure with a fixing seat that allows for removable and replaceable electric poles and incorporates drainage holes at the lower end to prevent water accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If LED bulbs are cast in one piece with fixed electric pins, then the manufacturing process is simple and fast, but the bulb must be scrapped when the electric pin breaks
Solution Approach 1:
The bulb is divided into separate modules: the bulb body and the electric pin assembly are independent components that can be separated. The electric pin assembly can be detached and replaced without discarding the entire bulb, thus improving repairability while maintaining manufacturing efficiency through modular assembly.
Solution Approach 2:
Instead of discarding the entire bulb when the electric pin breaks, only the electric pin assembly is replaced while the bulb body is retained and reused. This reduces waste and extends the product lifecycle.
2Ease of manufacture
If LED bulbs have a sealed solid structure, then the manufacturing process is simple, but water accumulates inside the bulb when placed outdoors
Solution Approach 1:
A waterproof membrane is introduced as a flexible barrier between the sealed bulb structure and the external environment. This thin film allows the bulb to maintain its simple sealed construction while preventing water accumulation through the waterproofing function of the membrane.
Solution Approach 2:
The waterproof membrane acts as an intermediary element between the bulb's internal sealed environment and the external outdoor conditions. It mediates the conflict by blocking water while allowing the simple sealed structure to be maintained.
3Device complexity
If the bulb is made as a single integrated piece, then the structure is simple and cost-effective, but the entire bulb must be replaced when any component fails
Solution Approach 1:
The bulb structure is segmented into replaceable modules (bulb body and electric pin assembly), maintaining overall structural simplicity while enabling selective replacement of failed components, thus improving reliability without significantly increasing complexity.
