Writing Implement Grip with Controlled Aroma Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scented writing instruments emit aromas permanently until all volatile liquid has evaporated, lacking control over aroma release and potentially causing cross-contamination of scents during storage.
Innovation Solution
A grip for writing implements featuring a liquid reservoir with a volatile liquid, a user actuator to pressurize the liquid, and a fragrance diffusion member, allowing controlled release of aroma upon evaporation of the volatile liquid, independent of writing usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the liquid reservoir is left open for continuous evaporation, then the aroma is emitted permanently, but the aroma emission function has limited lifetime and causes cross-contamination during storage
Solution Approach 1:
The system transitions from static continuous evaporation to dynamic controlled evaporation. The user actuator enables on-demand activation of the liquid transfer member, allowing the grip to switch between sealed storage state and active aroma emission state based on user input, thereby extending functional lifetime and preventing cross-contamination.
Solution Approach 2:
The system changes the evaporation parameter from continuous to intermittent. By controlling the opening of the liquid transfer member through the user actuator, the system regulates when evaporation occurs (only when needed for aroma release) versus when the reservoir remains sealed (during storage), thus managing both lifetime and cross-contamination issues.
2Object-generated harmful factors
If the grip is sealed during storage, then cross-contamination is prevented, but aroma cannot be released without user actuation
Solution Approach 1:
The system enables users to control aroma release through simple actuation of the user actuator. The mechanical action of pressing the actuator automatically opens the liquid transfer member and initiates aroma emission without requiring complex controls or external mechanisms, making the system easy to operate while maintaining sealed storage during non-use.
Solution Approach 2:
The system provides dynamic control over the sealed state. The user actuator serves as a simple interface to transition between the sealed storage configuration (preventing cross-contamination) and the open emission configuration (allowing aroma release), giving users straightforward control over when aroma is released.
3Productivity
If the liquid transfer member is always open, then aroma is continuously emitted, but volatile liquid evaporates unnecessarily during storage
Solution Approach 1:
The system dynamically controls the opening state of the liquid transfer member based on user needs. The user actuator enables the transfer member to open only when aroma emission is desired, keeping it closed during storage periods, thereby preventing unnecessary evaporation and loss of volatile liquid while maintaining availability when needed.
Solution Approach 2:
The system changes the operational parameter of the liquid transfer member from continuously open to conditionally open. The user actuator controls when the transfer member opens (only when aroma release is required) versus when it remains closed (during storage), optimizing both emission availability and preventing unnecessary liquid evaporation.
