Solution Overview
Problem
Conventional suspended mount apparatuses for heavy goods face challenges in achieving both space saving and weight saving while maintaining adequate fatigue strength, often resulting in larger and heavier designs that compromise on sound and frictional wear prevention.
Innovation Solution
A mount apparatus comprising resin-made attachment parts and vibration receiving parts, supported by a dropout prevention plate arranged at a predetermined interval, with an elastic member interposed between the vibration receiving part and the dropout prevention plate to prevent collision and enhance durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the mount apparatus is made of resin to achieve weight saving, then weight is reduced, but fatigue strength may be insufficient
Solution Approach 1:
The invention uses resin materials with high strength-to-weight ratio for the attachment parts and vibration receiving part, creating a composite structure that maintains fatigue strength while achieving weight saving compared to conventional metal constructions
Solution Approach 2:
The invention changes the material parameters by selecting specific resin materials with optimized mechanical properties, and adjusts structural parameters such as wall thickness and reinforcement ribs to ensure adequate fatigue strength while minimizing weight
2Area of stationary object
If the dropout prevention plate is arranged close to the vibration receiving part to prevent collision, then space is saved, but frictional wear and sound of beating occur
Solution Approach 1:
The invention introduces an elastic member as an intermediary element between the dropout prevention plate and the vibration receiving part. This elastic member acts as a mediator that prevents direct contact and collision between the plate and the vibration receiving part, thereby eliminating frictional wear and sound of beating while maintaining compact spacing
Solution Approach 2:
The elastic member provides beforehand cushioning by being pre-installed between the dropout prevention plate and the vibration receiving part. This cushioning layer prevents direct impact and collision before they can occur, eliminating frictional wear and unwanted noise while maintaining the compact design
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
The solution achieves both space and weight savings while improving fatigue strength, reducing sound and frictional wear, and enhancing the overall strength and durability of the mount apparatus.
Implementation Method 1
a vibration receiving part (20), fixed to the attachment parts (10), for receiving input vibrations from a vibration source through an elastic material
Implementation Method 2
an elastic member is preferably interposed between the vibration receiving part and the dropout prevention plate. In this way, collision between the vibration receiving part and the dropout prevention plate can be preferably prevented, and sound of beating and frictional wear caused by the collision
