Retractable Support Leg Design for Housing Stability and Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support parts for items like multifunction machines and furniture often obstruct passage and are difficult to retract when the items are moved, as they protrude from the housing structure, which can lead to instability and mobility issues.
Innovation Solution
A support part design featuring a leg part with an outer leg portion that protrudes from the housing to contact the installation surface, an inner leg portion that extends inward, and a connecting portion, along with a raising/lowering mechanism and operation section that allows the support part to be easily raised and lowered, minimizing obstruction and enhancing stability and mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the support part protrudes from the outer side surface of the housing to provide stable support, then the stability of the item is improved, but the support part obstructs passage and reduces mobility
Solution Approach 1:
The support part is designed to be movable between a lowered state (protruding from the housing to provide stability) and a retracted state (stored inside the housing to enable mobility). The raising/lowering section allows the support part to transition between these states dynamically, resolving the contradiction between stability and mobility.
Solution Approach 2:
The support part is stored within the housing structure when not in use, with the inner leg portion housed inside the outer side surface of the housing. This nesting arrangement allows the support part to be compact during transport while still providing full support functionality when deployed.
2Ease of operation
If the support part is designed to be easily retracted for mobility, then the ease of operation is improved, but the stability support capability may be compromised
Solution Approach 1:
The support part incorporates a raising/lowering mechanism that enables easy transition between extended and retracted states. The operation section provides user control over this movement, ensuring that retraction is simple while the extended position provides adequate support stability.
3Reliability
If the entire support part protrudes from the housing, then the support function is maximized, but the device complexity and obstruction increase
Solution Approach 1:
The support part is divided into an outer leg portion and an inner leg portion, with the inner portion being retractable while the outer portion remains fixed or partially fixed. This segmentation allows the support function to be maintained through the outer portion while the inner portion provides adjustable support that can be retracted to reduce complexity and obstruction.

AI summary
A support part that supports a lower portion of a housing upon installation of an item on an installation surface, includes: a leg part including an outer leg portion, an inner leg portion, and a connecting portion, the outer leg portion being provided so as to come into contact with the installation surface and extending from a gap between the lower portion of the housing and the installation surface so as to protrude outward of an outer side surface of the housing, the inner leg portion being disposed above the outer leg portion and extending inward of the outer side surface of the housing, the connecting portion connecting the outer leg portion and the inner leg portion inside the outer side surface of the housing; a raising/lowering section that is provided at the lower portion of the housing and that supports the inner leg portion of the leg part so as to raise and lower the inner leg portion; and an operation section that is provided so that a portion of the operation section protrudes outward of an outer side surface of the connecting portion of the leg part and that operates a raising/lowering movement of the raising/lowering section.
