Solution Overview
Problem
In home appliances with rotatable doors, decorative plates attached to the front surface often interfere with the main body when opened due to a step difference in height, and existing solutions require separate fastening members for attachment.
Innovation Solution
A home appliance design featuring a holder moveably mounted to the door with a wire connected to the main body, allowing the decorative plate to move upward when the door opens and return by self-weight when closed, without the need for additional fastening members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the decorative plate is positioned lower than the door to match furniture design, then the aesthetic appearance is improved, but the decorative plate interferes with the main body when the door is opened
Solution Approach 1:
The decorative plate is made movable rather than fixed, allowing it to change position dynamically. When the door opens, the decorative plate moves upward along the guide slot to avoid interfering with the main body, and returns to its original lower position when the door closes, maintaining aesthetic appearance.
Solution Approach 2:
The decorative plate is separated from the door structure into an independent movable component mounted on a holder. This segmentation allows the decorative plate to move independently relative to the door, resolving the conflict between aesthetic positioning and operational clearance.
2Reliability
If a separate fastening member is used to attach the decorative plate, then the attachment reliability is improved, but the device complexity and ease of manufacture deteriorate
Solution Approach 1:
The fastening function is merged into the holder structure itself. The holder includes a receiving space that accommodates the decorative plate, and the wire is integrated into the holder to provide both suspension and attachment functions, eliminating the need for separate fastening members.
Solution Approach 2:
The holder serves multiple functions: it mounts the decorative plate, guides its movement along the slot, and integrates the wire attachment mechanism. This multi-functionality reduces the number of components while maintaining reliable attachment.
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
Prevents interference between the decorative plate and the main body during door rotation and allows easy attachment and detachment of the decorative plate without additional fastening components.
Implementation Method 1
a wire connected to the holder and the main body such that a tension thereof varies depending rotation of the door, and configured to move the holder by the tension
Implementation Method 2
The decorative plate may be moved in a lower direction of the door by self-weight of the decorative plate when the door is closed
