Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate vibration isolation pad and load sensor are used, then vibration isolation and load measurement functions are achieved, but device complexity and installation difficulty increase

Engineering Contradiction:

Improvevibration isolation and load measurement capabilityVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the vibration isolation pad and load sensor into a single integrated element. The load sensor is embedded within the vibration isolation pad structure, allowing both vibration isolation and load measurement functions to be performed by one component rather than requiring separate elements, thereby reducing device complexity and installation difficulty

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated element serves multiple functions simultaneously: it provides vibration isolation through the elastic material layer while also measuring load through the embedded sensor. This multi-functional design eliminates the need for separate vibration isolation and load measurement components, simplifying the overall system

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate vibration isolation pad and load sensor are used, then vibration isolation and load measurement functions are achieved, but installation time and ease of installation deteriorate

Engineering Contradiction:

Improvevibration isolation and load measurement capabilityVSAvoidinstallation ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

By merging the vibration isolation pad and load sensor into one integrated component, the installation process is simplified from installing two separate elements to installing a single element, directly improving ease of operation and reducing installation time

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The load sensor is pre-integrated into the vibration isolation pad during manufacturing, so that the sensor positioning and connection work is completed in advance. This preliminary action eliminates the need for complex on-site installation procedures for the sensor, making the overall installation easier and faster

Inventive Principle:

Principle #10Preliminary action

3Reliability

If integrated load sensor arrangement is added to vibration isolation pad, then load measurement capability is achieved, but manufacturing complexity increases

Engineering Contradiction:

Improveload measurement capabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The load sensor is nested within the vibration isolation pad structure, with the sensor embedded in the elastic material layer. This nesting approach allows the sensor to be integrated into the pad during the molding or assembly process, avoiding the need for separate complex assembly steps and reducing manufacturing complexity

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The integration of the load sensor with the elastic material layer creates a composite structure that combines the vibration isolation properties of the elastic material with the measurement capabilities of the sensor. This composite approach allows both functions to be achieved through a unified manufacturing process rather than requiring separate manufacturing steps

Inventive Principle:

Principle #40Composite materials
