Vehicle Dispenser With Adjustable Movable Lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air fresheners for vehicles lack adjustable fragrance control and do not provide controlled ambient emission of fragrances when the vehicle is not in use, varying in fragrance intensity based on time of day and year.
Innovation Solution
A dispenser with a housing containing a resistive heating wire in thermal communication with a volatile material container, featuring a movable lid with adjustable positions and a permeable membrane to control fragrance release, allowing for user-adjustable fragrance intensity and ambient emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a typical air freshener uses a fixed heating element without adjustment mechanisms, then the device structure remains simple, but the fragrance intensity cannot be controlled or adjusted
Solution Approach 1:
The patent implements a movable lid with multiple adjustable positions (fully closed, partially open, fully open) that allows users to dynamically control fragrance emission. This mechanical adjustment mechanism enables fragrance intensity control without complex electronics, resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The patent changes the physical parameter of lid position (open/closed states) to control the emission parameter of fragrance. By adjusting the lid position, users can vary the fragrance intensity and ambient emanation, achieving controllable fragrance release through a simple mechanical parameter change
2Reliability
If a typical air freshener operates continuously without control mechanisms, then the device remains simple, but the fragrance emission varies with time of day and year without user control
Solution Approach 1:
The movable lid provides dynamic control over fragrance emission, allowing users to adjust between fully closed (no emission), partially open (controlled emission), and fully open (maximum emission) states. This ensures reliable controlled ambient emanation regardless of time of day or year, while keeping the control mechanism mechanically simple
3Quantity of substance
If the lid is fully closed to prevent fragrance loss, then fragrance retention is improved, but no fragrance is emitted to the environment
Solution Approach 1:
The movable lid enables dynamic adjustment between retention and emission modes. When fully closed, fragrance is retained in the reservoir; when partially or fully open, fragrance is emitted to the environment. This single mechanical component resolves the contradiction by allowing users to select the desired operational state
