Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a link mechanism with multiple members capable of relative rotational movement is used, then the device can achieve complex motion patterns, but frictional forces and jamming in coupling portions cause unstable operation and vibration absorption failure
Solution Approach 1:
The patent extracts the vibration absorption function from the complex link mechanism by introducing a dedicated vibration absorption member. This separate component specifically handles vibration damping without interfering with the motion control functions of the link mechanism, thereby resolving the instability caused by friction and jamming while preserving the complex motion capability.
Solution Approach 2:
The patent segments the system into distinct functional modules: the link mechanism for motion control and the vibration absorption member for vibration damping. This segmentation allows each component to perform its specific function optimally without the interference that occurs in integrated designs, improving overall reliability.
2Ease of operation
If magnetic forces are used to restrain rotation of the support member, then rotation can be controlled without contact, but the magnetic force generation requires additional components and complexity
Solution Approach 1:
The patent replaces the magnetic force-based rotation restraint with a mechanical vibration absorption member that uses elastic deformation to achieve the same restraining effect. This mechanical approach eliminates the need for magnets and opposite pole magnets, reducing device complexity while maintaining ease of operation.
3Use of energy by moving object
If rotational movement in coupling portions is used to reduce motor load, then vibration can be absorbed through contact, but frictional forces and jamming cause unstable operation
Solution Approach 1:
The patent introduces a vibration absorption member as an intermediary component between the motor and the load. This member absorbs vibrations through elastic deformation before they can affect the motor, reducing motor load variations while avoiding the friction and jamming problems of direct contact-based vibration absorption.
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
Stable absorption of vibrations in multiple directions, preventing friction and jamming, ensuring consistent operation and effective crushing of samples.
Implementation Method 1
a first elastic member which is coupled with each of the first support member and the base and is stretchable in a longitudinal direction... Vibration of the first support member in plural directions is absorbed by the base via the first elastic member
Implementation Method 2
the inclined shaft is rotated and driven around an axis line of the rotating shaft... the first support member vibrates around the axis line of the inclined shaft and vibrates to cause its outer periphery to rise and fall

AI summary
A sample crushing device is provided having a function of stably absorbing vibration of a support member supporting a sample container and vibration of other members which accompanies the vibration. When a rotating shaft 20 is rotated and driven by rotation driving mechanism, revolving motions of a first support member 12 around an axis line C1 of a rotating shaft 20 and rotational movement of an inclined shaft 10 around an axis line C2 are restrained by a base 1 via first elastic members 14. As a result, the first support member 12 and sample containers 41 are vibrated in plural directions, and samples housed in the sample containers 41 are crushed by crushing media. Vibration of the first support member 12 in plural directions is absorbed by a base 1 via the first elastic members 14 coupled with each of the first support member 12 and the base 1.
