Ice Bucket Locking Flap Design for One-Handed Refrigerator Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for ice buckets in refrigerators require both hands to operate, have complex structures, high material costs, and suffer from reduced performance due to spring aging and corrosion, leading to reduced user convenience and reliability.
Innovation Solution
A locking device for ice buckets featuring a projection, an elastic module with a wave-shaped elastic piece, a locking flap, and a cover part, which provides one-handed operation and improved durability without using metal springs, ensuring consistent elastic force over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal spring is used in the locking device, then the locking mechanism can be implemented, but the elastic force is reduced over time due to spring aging and corrosion
Solution Approach 1:
The patent replaces the metal spring mechanical system with an elastic piece made of polymer material. This substitution eliminates the problems of spring aging and corrosion while maintaining the elastic force generation function. The polymer elastic piece provides consistent elastic force over time without the degradation issues associated with metal springs.
Solution Approach 2:
The patent uses polymer material for the elastic piece instead of traditional metal spring material. This material change provides both the necessary elastic properties and resistance to corrosion and aging, solving the reliability and durability contradiction simultaneously.
2Reliability
If a spring and opening button are separately installed, then the locking function is achieved, but the structure becomes complicated and material cost increases
Solution Approach 1:
The patent combines the spring and opening button functions into a single integrated elastic piece. The elastic piece itself serves as both the locking mechanism and the release mechanism, eliminating the need for separate components. This merging simplifies the structure, reduces material cost, and maintains the locking function.
Solution Approach 2:
The elastic piece performs multiple functions: it provides the locking force to hold the ice bucket in place, and it can be pressed to release the locking mechanism. This multi-functionality eliminates the need for separate spring and button components, reducing structural complexity.
3Reliability
If both hands are required to operate the opening button, then the locking mechanism can be released, but user convenience is reduced
Solution Approach 1:
The elastic piece is designed to be pressable by a single hand, allowing the user to easily release the locking mechanism without requiring both hands. The integrated design provides a large enough pressing surface on the elastic piece that can be easily actuated by one hand, improving accessibility while maintaining reliable locking operation.
