Leg Member Mounting Structure for Vibration Isolation in Electronic Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatuses suffer from sound quality deterioration due to internal and external vibrations, which are not effectively mitigated by existing leg member mounting structures, and these structures often complicate installation and increase manufacturing processes.
Innovation Solution
A mounting structure for a leg member that includes a bottom plate with first female screw holes and a support column with a first male screw member and shaft member, allowing the leg member to be integrally attached to the housing while minimizing vibration transmission, using a loosely fitted shaft member and additional support members to prevent separation and rotation, eliminating the need for retaining members and simplifying manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the insulator is fixed to the housing by screwing, then the insulator is securely attached to the housing, but external vibration from the floor surface is easily transmitted to the housing
Solution Approach 1:
The support column is divided into two functional parts: a shaft member for loose fitting that provides vibration isolation, and a first male screw member for secure attachment. This segmentation allows each part to fulfill its specific function without compromising the other.
Solution Approach 2:
The shaft member acts as an intermediary between the housing and the floor surface, providing a loose fit that allows relative movement and thereby isolates the housing from vibration while still providing structural support.
2Object-affected harmful factors
If the insulator is used without being fixed to housing, then vibration transmission is reduced, but installation work becomes time-consuming and effort-intensive as the user must hold the housing floating from the floor surface
Solution Approach 1:
The support column is divided into two functional parts: a shaft member for loose fitting that provides vibration isolation, and a first male screw member for secure attachment. This segmentation allows each part to fulfill its specific function without compromising the other.
Solution Approach 2:
The shaft member's loose fit automatically provides vibration isolation without requiring additional components or complex installation procedures, while the first male screw member enables simple screw-in attachment.
3Stability of the object's composition
If a retaining member is attached to the tip end portion of the support column to prevent it from coming off, then the support column is secured, but the degree of freedom is reduced in arranging components inside the housing and additional manufacturing processes are required
Solution Approach 1:
The first male screw member integrates both the securing function (preventing the support column from coming off) and the attachment function (screwing into the housing) into a single component, eliminating the need for separate retaining members and reducing structural complexity.
Solution Approach 2:
The first male screw member serves multiple functions: it secures the support column to the housing, provides the attachment mechanism, and eliminates the need for separate retaining members, thereby simplifying the overall structure.

AI summary
A mounting structure of a leg member includes a bottom plate constituting a housing and a leg member. A first female screw hole is formed on the bottom plate. The leg member includes a leg member main body and a support column. The support column has a first male screw member and a shaft member. In case the first male screw member is screwed into the first female screw hole and passes from a bottom surface side to a top surface side of the bottom plate, the shaft member is loosely fitted in the first female screw hole and the first male screw member is locked to the top surface.
