Refrigerator Hinge Cam Adjustment for Door-to-Body Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator hinge supporting apparatuses lack the ability to adjust the gap between the main body and the door, leading to poor sealing, noise, and increased energy consumption due to inconsistent gap settings.
Innovation Solution
A hinge supporting apparatus featuring a cam member that varies the installation position of the connection member between the door and the main body, allowing for adjustable gap control through a simple structure comprising a connection member, cam member, and fixing member, enabling the gap to be narrowed or widened.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gap between the main body and the door is set to be narrower than a predetermined gap, then the sealing performance is improved, but the door cannot be closed well or noise occurs when the door is opened and closed
Solution Approach 1:
The hinge supporting apparatus employs a movable connection member that can be adjusted to different positions along the connection direction. This dynamic adjustment capability allows the gap between the door and main body to be optimized, resolving the contradiction between achieving narrow gap for sealing and maintaining sufficient gap for proper door operation and noise prevention.
2Object-affected harmful factors
If the gap between the main body and the door is set to be larger than the predetermined gap, then the door can be closed well and noise is reduced, but the main body and the door are unable to keep airtight
Solution Approach 1:
The adjustable connection member enables dynamic optimization of the gap size. Users can adjust the connection member to achieve the appropriate gap that balances noise reduction with airtightness requirements, resolving the contradiction between these two opposing requirements.
3Device complexity
If the hinge supporting apparatus is designed with fixed connection member position, then the structure is simple, but the gap between the main body and the door cannot be controlled
Solution Approach 1:
The hinge supporting apparatus is divided into separable components: a connection member that can be independently adjusted along the connection direction, a cam member for positioning, and a fixing member for securing. This segmentation allows the connection member to be repositioned to control the gap while maintaining overall structural simplicity.
Solution Approach 2:
The connection member is designed to be movable and adjustable rather than fixed, enabling gap control functionality. The adjustable design incorporates a cam member and fixing member that allow easy repositioning without significantly increasing overall device complexity.
4Adaptability or versatility
If the hinge supporting apparatus is designed with adjustable connection member position, then the gap control capability is improved, but the structure becomes more complex
Solution Approach 1:
The adjustment mechanism is segmented into distinct functional components: the movable connection member, the cam member for positioning, and the fixing member for securing. This segmentation allows each component to perform its specific function with simple design, avoiding unnecessary complexity in the overall structure.
Solution Approach 2:
The cam member acts as an intermediary between the connection member and the main body, providing a simple mechanical means for positioning and securing the connection member at different locations. This intermediary component enables gap control functionality without requiring complex adjustment mechanisms.
