Appliance Door Bearing Locking for Coordinated Pivot Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliance doors lack coordinated mobility and secure locking mechanisms, leading to inefficient operation and assembly processes.
Innovation Solution
A household appliance device with a locking unit featuring an elastic actuating means and a guide means that allows flexible operation and secure fixing of the door, incorporating a locking mechanism that can transmit spring force and engage in a recess for secure positioning, enabling coordinated mobility and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking unit with elastic actuating means is added to fix the door bearing unit, then the door mobility and positioning accuracy are improved, but the device complexity increases
Solution Approach 1:
The locking means is integrated into the guide means as a tooth-like extension, combining two separate components into one unified structure. This reduces the number of parts while maintaining the locking function, thereby improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The elastic actuating means automatically actuates the locking means to engage with the recess in the door bearing unit. The spring-loaded mechanism self-regulates to maintain proper engagement force, reducing the need for additional control components and simplifying the overall system while ensuring reliable positioning.
2Ease of manufacture
If the locking means is designed as an integrated tooth with guide means, then the manufacturing complexity is reduced, but the assembly flexibility may be limited
Solution Approach 1:
While the locking means and guide means are integrated, the locking unit is designed as a separate modular assembly that can be independently positioned along the guide surface. This segmentation at the assembly level maintains manufacturing simplicity while providing flexibility in assembly configuration and adaptation to different door positions.
Solution Approach 2:
The locking unit can be dynamically positioned at different locations along the guide surface before final assembly. The elastic actuating means allows the locking means to engage with the recess at various positions, providing adaptability in assembly configuration while the integrated tooth design maintains ease of manufacture.
3Volume of moving object
If the door is largely incorporated into the storage space, then the space utilization is improved, but the door accessibility and operation convenience may be reduced
Solution Approach 1:
The door bearing unit is designed to extend beyond the storage space in the vertical dimension while the door itself is largely incorporated horizontally. The locking unit operates in this extended dimension, allowing the door to be securely stored within the storage space volume while maintaining accessibility through the vertically extended bearing unit that protrudes for operation.
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 solution provides enhanced mobility and secure locking of the appliance door, ensuring stable operation and convenient assembly by allowing flexible actuation and secure engagement of the locking mechanism, improving user experience and component efficiency.
Implementation Method 1
the locking means is intended to transmit a spring force to the guide means
Implementation Method 2
the locking unit has at least one locking means and at least one elastic actuating means, which is intended to actuate the locking means
