Tapered Bulb Socket Minimizing Shadow Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bulb sockets create shadow projections due to their design, resulting in undesirable dark spots by obstructing the light generated by bulbs.
Innovation Solution
A bulb socket with a tapered second portion and a first portion having a substantially rectangular configuration, allowing the light to radiate in all directions without obstruction, minimizing shadow projections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the socket housing circumference is equal to or exceeds the bulb circumference to ensure proper bulb reception and contact engagement, then the bulb can be properly received and electrically connected, but the socket creates shadow projections that block light and cause undesirable dark spots
Solution Approach 1:
The socket is divided into two distinct portions: a first portion with a larger circumference for receiving the bulb and making electrical contacts, and a second portion with a tapered configuration extending from the first portion. This segmentation allows each portion to serve its specific function without the entire socket housing creating shadow projections that would block light.
Solution Approach 2:
Different portions of the socket are given different dimensional characteristics - the first portion has a circumference equal to or exceeding the bulb circumference for proper reception, while the second portion has a reduced profile with tapered surfaces that minimize shadow projection. This local differentiation resolves the contradiction between reliable bulb reception and unobstructed light output.
2Ease of manufacture
If the socket housing is dimensioned to accommodate the bulb base and contacts, then proper electrical connection is achieved, but the housing creates shadow projections that block some of the light generated by the bulb
Solution Approach 1:
The socket design transitions from a uniform cylindrical housing to a multi-dimensional structure with a first portion for bulb reception and a second portion with tapered surfaces extending in a different dimensional orientation. This dimensional change allows the socket to maintain contact engagement functionality while reducing the profile in the light path direction, thereby minimizing shadow projections and energy loss.
3Stability of the object's composition
If the socket creates a housing with circumference equal to or exceeding the bulb circumference for proper bulb reception, then the bulb can be securely held, but shadow projections are created that cause unwanted dark spots
Solution Approach 1:
The harmful shadow-projecting portion is extracted from the overall socket structure by creating a separate second portion with a reduced profile that extends from the first portion. This extracted portion does not create shadow projections, while the first portion maintains the necessary circumference for secure bulb holding and positioning.

AI summary
A bulb socket for receiving a bulb therein. The bulb socket includes a first portion and a second portion. The first portion has a bulb receiving opening. The second portion extends from the first portion. The second portion has first outside surfaces which are tapered inward, such that the perimeter of the second portion proximate the first portion is less than the perimeter of the second portion spaced from the first portion. The second portion does not obstruct the performance of the bulb, allowing approximately all of the light capacity of the bulb to be utilized.
