Home Appliance Wire Guide Layout for Heat and Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home appliances with high internal temperatures, such as cooking appliances, pose a risk of wire overheating and damage due to exposure to high temperatures, and existing wire arrangements either suffer from poor workability during maintenance or increase noise and manufacturing costs.
Innovation Solution
The implementation of a wire guide system within the home appliance casing that shortens the wire installation path, insulates wires from heat and cold air, and minimizes exposure by arranging wires slightly toward the rear, away from the front of the appliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wire is disposed inside the main body of the home appliance, then the wire is protected from external damage, but the wire is exposed to high temperatures from the heating device causing overheating and damage
Solution Approach 1:
The wire routing is divided into multiple segments: a first wire extending from the door along the front surface to a first position, and a second wire extending from the first position to the rear surface. This segmentation allows the wire to avoid the high-temperature heating device while maintaining electrical connection, resolving the contradiction between protection and temperature exposure.
Solution Approach 2:
The first position acts as an intermediary point where the wire transitions from the front surface to the rear surface of the home appliance. This intermediary location allows the wire to bypass the high-temperature zone near the heating device, enabling the wire to maintain connectivity while avoiding thermal damage.
2Temperature
If the wire is arranged around the outer edge of the casing to avoid heat, then the wire temperature is reduced, but the wire length increases leading to increased manufacturing costs and noise
Solution Approach 1:
The wire routing utilizes different regions of the home appliance casing with different thermal characteristics. The wire passes through the front surface, travels along edges to a first position, then to the rear surface, strategically using cooler regions while minimizing overall path length. This local quality approach reduces wire temperature without significantly increasing wire length or manufacturing cost.
3Temperature
If the wire is extended to the rear of the home appliance to avoid heat, then the wire is insulated from heat, but the wire length increases causing increased noise in communication and imaging devices
Solution Approach 1:
The wire is routed to extend beyond the rear surface of the home appliance to a second position before connecting to the electronic component. This preliminary extension allows the wire to maintain a shorter effective length within the noisy environment, reducing noise interference in communication and imaging devices while still providing heat insulation through the extended path.

AI summary
An appliance includes a casing having a storage space, a door, a first electronic component disposed outside the casing, a second electronic component disposed at the door, a wire, and a wire guide. The door is disposed at a front of the storage space and configured to open and close at least a portion of the storage space. The wire is configured to electrically connect the first electronic component and the second electronic component. The wire guide is disposed at the casing and has a guide channel that is configured to store the wire.
