Lip Pen Assembly Automatic Light Activation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lip pen assemblies require users to maintain contact with terminals to activate light bulbs, limiting hand pose and causing discomfort.
Innovation Solution
A lip pen assembly with a container and neck system, where light bulbs are automatically turned on when the pen is removed and off when inserted, using a biasing member and protrusions to control battery contact with light bulb poles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user's hand maintains contact with terminals to activate light bulbs, then the light bulbs are turned on, but the user's hand pose is limited and causes discomfort
Solution Approach 1:
The system automatically detects when the lip pen is removed from the container and activates the light bulbs without requiring continuous hand contact with terminals. The protrusions on the seal ring automatically make or break contact with the terminals based on the pen's position, enabling hands-free operation.
Solution Approach 2:
The manual mechanical contact system (user's hand touching terminals) is replaced with an automatic mechanical detection system using protrusions on the seal ring that respond to the pen's position in the container, eliminating the need for deliberate hand contact.
2Ease of operation
If the light bulbs are automatically turned on when the lip pen is removed from the container, then hands-free operation is enabled, but the device complexity increases
Solution Approach 1:
The container and neck assembly serve multiple functions: they store the lip pen, detect its position through the seal ring's movement, control the electrical circuit for the light bulbs, and provide structural support. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The detection mechanism, circuit control, and structural components are merged into an integrated system where the seal ring's physical movement simultaneously triggers the electrical connection/disconnection and provides the mechanical framework, simplifying the overall device architecture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables hands-free operation of light bulbs, allowing users to move freely without restricting hand positions while using the lip pen.
Implementation Method 1
A biasing member has a first end contacting the first end of the at least one battery and pushes the at least one battery toward the first pole
Implementation Method 2
At least one light bulb extends through the base and has a first pole and a second pole... the two light bulbs 22 are turned on so that the user can see her lips in the mirror 20 by the light provided by the light bulbs 22

AI summary
A lip pen assembly includes a container and a lip pen is removably inserted into the container. The lip pen has a base and a handle, the base is mounted to a neck extending from an end of the container and two light bulbs are connected to the base. A seal ring has a plurality of protrusions which extend through an end of the handle. The two light bulbs include two first poles and two second poles. A cover is removably connected to the base and has a biasing member which pushes a battery and the battery pushes the protrusions to be inserted into the base when the lip pen together with the base is removed from the container, so that the battery is in contact with the first terminals to light up the light bulbs.
