Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light emitting diode assembly is placed in a hollow bulb shell interior, then illumination is provided, but structural integrity and moisture resistance may be compromised
Solution Approach 1:
The bulb shell is divided into two main segments: the hollow bulb shell interior that transmits light, and the lamp assembly extension that houses and protects the LED assembly. This segmentation allows the light-transmitting portion to remain simple and transparent while the extension portion provides structural support and moisture protection through the heat shrinkable sleeve and locking structure.
Solution Approach 2:
A heat shrinkable sleeve is introduced as an intermediary component that wraps around the lamp assembly extension and LED assembly. This sleeve acts as a barrier against moisture while allowing the LED assembly to be securely held in place through contraction, thus protecting the illumination system without interfering with its light-emitting function.
2Reliability
If a locking structure and heat shrinkable sleeve are added to secure the LED assembly, then reliability improves, but device complexity increases
Solution Approach 1:
The locking structure and heat shrinkable sleeve are combined into a single integrated solution. The heat shrinkable sleeve simultaneously performs multiple functions: it secures the LED assembly through contraction, provides moisture resistance, and simplifies the overall assembly process by eliminating the need for separate mounting brackets or adhesive applications.
Solution Approach 2:
The heat shrinkable sleeve utilizes parameter change through thermal contraction. When heated, the sleeve shrinks to conform tightly around the lamp assembly extension and LED assembly, creating a secure mechanical bond and moisture barrier without requiring complex fastening mechanisms or multiple assembly steps.
3Ease of manufacture
If the bulb shell and lamp assembly extension are formed as a single structure, then fabrication cost is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The bulb shell and lamp assembly extension are pre-formed as a single molded structure before the LED assembly is installed. This preliminary formation of the housing structure allows for cost-effective mass production through injection molding or similar processes, while the subsequent separate installation of the LED assembly maintains flexibility for quality control and assembly variations.

AI summary
Disclosed is a light assembly that has an integral bulb shell and lamp assembly extension that are formed from a single structure. A separate LED assembly can be inserted into an opening in the lamp assembly extension and held in place by a heat shrinkable sleeve and a locking structure in the lamp assembly extension. The lamp assembly is less expensive and easier to assemble than lamp assemblies using multiple parts. The lamp assemblies can be easily constructed by simply inserting the LED assemblies into the light assembly. The light string can use serial connections by forming LED assemblies on a single strand of an insulated conductor and simply inserting LED assemblies in the light assemblies.
