Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household refrigeration appliances with interior lighting often have complex and difficult installation processes for lighting fixtures, which can be time-consuming and require specialized skills.
Innovation Solution
A household refrigeration appliance design featuring a pocket-shaped recess in the inner container for easy installation of interior lighting, using a counter-fastening device that integrates with the housing of the lighting fixture, allowing for simple and secure attachment, particularly utilizing LEDs and a heat-insulating foam for efficient cooling and illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening methods are used for interior lighting, then the lighting can be securely attached, but the installation process becomes complex and time-consuming
Solution Approach 1:
The fastening system is divided into two separate components: a fastening device integrated into the pocket-shaped recess of the inner container, and a counter-fastening device integrated into the housing of the interior lighting. This segmentation allows each component to be independently designed and manufactured, simplifying the overall installation process while maintaining secure attachment.
Solution Approach 2:
The counter-fastening device is nested within the housing of the interior lighting fixture, with the fastening device nested within the pocket-shaped recess of the inner container. This nested structure allows for compact integration without adding external complexity to either the lighting fixture or the container.
2Reliability
If complex fastening systems are used, then secure attachment is achieved, but installation requires specialized skills and more time
Solution Approach 1:
The fastening system is designed to be self-aligning and self-locking. The fastening device with its opening and the counter-fastening device with its overlapping areas automatically guide each other into the correct position during installation, eliminating the need for specialized alignment skills or additional fastening steps.
Solution Approach 2:
Instead of using a traditional approach where the lighting fixture has the fastening mechanism and the container has the receiving structure, this invention inverts the design by integrating the fastening device into the container's pocket-shaped recess and the counter-fastening device into the lighting housing. This inversion simplifies the installation process while maintaining attachment security.
3Ease of operation
If simple fastening methods are used, then installation is easy, but the attachment may not be secure
Solution Approach 1:
The fastening system combines two different structural elements (the fastening device with its opening and the counter-fastening device with its overlapping areas) that work together to provide both ease of installation and secure attachment. The complementary design of these two components creates a robust fastening solution.
Solution Approach 2:
The overlapping areas of the counter-fastening device are designed with curved surfaces that complement the shape of the opening in the fastening device. This curved geometry allows for easy insertion while providing substantial mechanical interlocking for secure attachment.
