Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household refrigeration appliances face challenges in installing drain pipes due to their rigid design, which results in fixed positions that do not accommodate different orientations of inner containers, leading to inefficient use of space and increased production and assembly efforts for various angle configurations.
Innovation Solution
A drain pipe with sections of different elasticities allows for flexible positioning and adjustment relative to the socket, enabling a secure and precise coupling while maintaining dimensional stability, allowing a single drain pipe to be used across various inner container configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid drain pipe is used, then dimensional stability is ensured, but positioning flexibility is reduced
Solution Approach 1:
The drain pipe is divided into multiple sections with different material properties. The first section (15) is made of elastic material to provide positioning flexibility, while the second section (18) is made of rigid plastic material to provide dimensional stability. This segmentation allows each part to fulfill its specific functional requirement independently.
Solution Approach 2:
Different sections of the drain pipe are assigned different material qualities based on their functional requirements. The first section has elastic properties for adaptation, while the second section has rigid properties for stability. This local differentiation of material properties resolves the contradiction between flexibility and stability.
2Adaptability or versatility
If multiple drain pipes with different angles are produced, then adaptability to various inner containers is improved, but production effort and complexity increase
Solution Approach 1:
A single drain pipe design with an elastic first section can accommodate multiple inner container configurations and socket orientations. The elastic section adapts to different angles and positions, making one drain pipe type universal for various applications, thereby eliminating the need to produce multiple specialized drain pipes.
Solution Approach 2:
The drain pipe incorporates an elastic, dynamically adaptable section that can change its shape and angle to fit different mounting configurations. This dynamic property allows a single static component to serve multiple functional positions, reducing the variety of components needed.
3Manufacturing precision
If a rigid drain pipe is positioned to fit different socket orientations, then coupling precision is improved, but forces on the connection piece increase
Solution Approach 1:
The material parameter of the first section is changed to elastic material, allowing it to deform and adapt to different socket orientations without applying excessive forces. This parameter change enables precise coupling while reducing mechanical stress on the connection piece.
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
This solution facilitates a more flexible and needs-based installation of the drain pipe, reducing installation complexity and space requirements, while enabling precise positioning without applying undue forces on the connection piece, thus improving usability and reducing production costs.
Implementation Method 1
The first pipe section, with the particularly greater material elasticity, is arranged so that it overlaps with the socket at least in regions when it is mounted on the socket
Implementation Method 2
The drain pipe has a first pipe section, the material of which has a first elasticity, and the drain pipe has a second pipe section, viewed along a longitudinal axis of the drain pipe, that is different from the first pipe section and the material of which has a second elasticity that is different from the first elasticity
