Home Appliance Oblique Support Foot for Tip-Over Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home appliances risk falling when their center of weight is biased, potentially causing damage to the appliance and nearby objects or injury to users, especially when placed on uneven surfaces or when doors are opened and heavy items are placed inside.
Innovation Solution
A support device with a bracket and foot system is designed to be obliquely installed at a certain angle, with the point of support positioned forward to reduce the risk of falling, and is integrated into the appliance's design to prevent exposure and maintain appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the support device is installed at the bottom of the home appliance, then the home appliance can keep its balance, but the support device may be exposed to the outside and compromise the appearance
Solution Approach 1:
The support device is nested within the home appliance body structure. The bracket is coupled to the front surface and bottom of the body, with the foot extending downward but remaining integrated into the overall appliance design, allowing the support function to be hidden within the appliance's form factor.
Solution Approach 2:
The support device is asymmetrically configured with the bracket coupled to both the front surface and bottom of the body at different positions. The foot is obliquely disposed rather than vertically aligned, creating an asymmetric structure that maintains balance while being integrated into the appliance's appearance.
2Device complexity
If the support device is installed vertically, then the structure is simple, but the point of support is not positioned forward enough to prevent falling when center of gravity shifts
Solution Approach 1:
The support device employs asymmetric geometry where the bracket has different coupling positions on the front surface and bottom, and the foot is obliquely disposed at a certain angle rather than vertically. This asymmetric configuration positions the point of support forward to prevent falling while maintaining structural integrity.
Solution Approach 2:
The support device transitions from a vertical orientation to an oblique orientation in three-dimensional space. The foot is disposed at a certain angle relative to the ground, utilizing spatial dimensionality to position the support point forward while maintaining connection to the appliance body.
3Stability of the object's composition
If the foot is made wide for stability, then the contact area with ground increases, but the support device protrudes outward and affects appearance
Solution Approach 1:
The foot has an asymmetric cross-sectional shape that is wider in the direction providing stability while remaining narrow in the direction that would cause protrusion. This asymmetric geometry allows the foot to provide sufficient ground contact area for stability without extending beyond the appliance's outer轮廓.
Solution Approach 2:
The foot exhibits local quality variation where different portions have different dimensions. The foot is configured to have sufficient width at the ground contact point for stability, while tapering or narrowing as it extends upward to avoid protruding from the appliance body, creating locally optimized geometry.

AI summary
A home appliance having a support device configured to prevent the home appliance from falling. A home appliance includes a body having an openable front surface, and a support device having a bracket configured to be coupled to the body, and a foot configured to support the body by being coupled to the bracket, wherein the foot is provided such that a point of support supporting the body by making contact with the ground, is formed in one end portion of the foot.
