Spring-Loaded Wipes Dispenser Lid for Reliable Air Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wet wipe dispensers often fail to provide an adequate air seal, leading to drying out of wipes, and require manual closure, which can be forgotten, resulting in spoilage. Additionally, they can be cumbersome to use and may not accommodate different types of wipes effectively.
Innovation Solution
A dispenser with a spring-loaded lid and extrusion means that automatically closes, featuring a mounting system for the inner container and a removable panel with varying resistance sections to facilitate easy access and prevent fouling, ensuring only compatible wipes are used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple sealable lid is used to close the container opening, then the device complexity is reduced, but the reliability of sealing is insufficient causing wipes to dry out
Solution Approach 1:
The lid is designed with spring-loaded mechanism that automatically closes and seals the opening after each wipe is dispensed, eliminating the need for manual closure and ensuring consistent sealing without requiring user intervention
Solution Approach 2:
The lid transitions from a static simple sealable design to a dynamic spring-loaded system that moves between open and closed positions, providing automatic sealing action that maintains reliability while managing complexity through controlled motion
2Device complexity
If manual closure is required, then the device complexity is reduced, but the loss of time occurs due to user forgetfulness and repeated opening/closing operations
Solution Approach 1:
The spring-loaded lid performs the closure function automatically without user intervention, eliminating time lost to manual operations while maintaining a relatively simple mechanical structure
3Reliability
If extrusion means with high resistance is used to prevent sheet separation, then the reliability of sheet retention is improved, but the ease of operation deteriorates as users cannot easily access wipes
Solution Approach 1:
The extrusion means incorporates varying resistance sections with different resistance levels at different locations, allowing easy access at low-resistance areas while maintaining reliable retention at high-resistance sections
Solution Approach 2:
The resistance characteristic of the extrusion means is made variable rather than uniform, dynamically adapting the resistance level based on the location where the sheet passes through, enabling both easy access and reliable retention
4Device complexity
If uniform resistance extrusion means is used, then the device complexity is reduced, but the adaptability deteriorates as it cannot accommodate different types of wipes effectively
Solution Approach 1:
The extrusion means features varying resistance sections with different resistance characteristics at different locations, enabling adaptation to different wipe types and materials while maintaining a single integrated structure without requiring multiple interchangeable components
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
The dispenser maintains a seal to prevent drying, allows easy access to wipes, and accommodates different types by adjusting resistance, ensuring effective use and replacement of components.
