Solution Overview
Problem
In home appliances with rotatable doors, decorative plates attached to the front surface often interfere with the main body when the door is opened, causing a step difference and requiring complex fastening methods.
Innovation Solution
A system where a decorative plate is moved upward when the door opens, using a wire connected to a holder and the main body, guided by slots on the door, to prevent interference and allow easy attachment without separate 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 relative to the door through a guide slot mechanism. When the door opens, the decorative plate automatically moves upward along the guide slot to clear the interference zone with the main body. This dynamic adjustment resolves the contradiction by allowing the plate to maintain its aesthetic lower position when closed while avoiding interference when open.
Solution Approach 2:
The connection between the decorative plate and door is segmented into multiple components: the guide slot in the door, the movable mounting structure on the plate, and the wire constraint system. This segmentation allows independent movement of the decorative plate relative to the door, enabling the plate to adjust its position dynamically to avoid interference while maintaining aesthetic positioning.
2Reliability
If a separate fastening member such as a screw is used to attach the decorative plate, then the attachment reliability is improved, but the mounting complexity increases
Solution Approach 1:
The mounting structure integrates multiple functions into a single unified component system. The guide slot serves both as a movement guide and as part of the attachment mechanism. The wire constraint system combines positioning and securing functions. This merging eliminates the need for separate fastening members like screws while maintaining reliable attachment through the integrated mechanism.
Solution Approach 2:
The decorative plate's mounting structure utilizes the door's guide slot and the wire constraint system to automatically secure itself without requiring external fastening members. The wire passes through the mounting structure and attaches to the door, creating a self-contained attachment system that is both simple and reliable.
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 decorative plate interference with the main body during door rotation and allows easy mounting and detachment without additional fastening components.
Implementation Method 1
