Solution Overview

Problem

Conventional driving force transfer devices for end-effectors require multiple shafts with single rotational degrees of freedom, leading to increased size, manufacturing and maintenance costs, and complex assembly processes.

Innovation Solution

A driving force transfer device utilizing a single double shaft member with two rotational degrees of freedom, where the first and second rotation shafts receive driving forces from separate power transfer means, allowing the end-effector to have independent rotational movements, potentially using gears or pulleys for power transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple shafts with single rotational degrees of freedom are used, then the end-effector can achieve multiple rotational degrees of freedom, but the size of the driving force transfer device increases

Engineering Contradiction:
Improverotational degrees of freedomVSAvoidsize of driving force transfer device
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent combines multiple shaft functions into a single integrated shaft structure. The driving force transfer device uses one shaft that simultaneously provides multiple rotational degrees of freedom through different sections or modes of the same shaft, eliminating the need for separate shafts for each degree of freedom.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single shaft in the invention serves multiple functions that would traditionally require separate shafts. It provides multiple rotational degrees of freedom, transmits multiple driving forces, and connects to multiple power transfer means, making it a universal component that replaces several specialized shafts.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple shafts are used, then the end-effector can achieve multiple rotational degrees of freedom, but the manufacturing cost increases

Engineering Contradiction:
Improverotational degrees of freedomVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By merging multiple shaft functions into a single shaft, the patent reduces the total number of parts that need to be manufactured, processed, and quality-checked. This consolidation directly reduces manufacturing cost while maintaining the capability for multiple rotational degrees of freedom.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If multiple shafts are used, then the end-effector can achieve multiple rotational degrees of freedom, but the assembling steps increase

Engineering Contradiction:
Improverotational degrees of freedomVSAvoidassembling steps
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent reduces assembly complexity by combining multiple shaft assembly steps into a single shaft installation. Instead of aligning and fastening multiple separate shafts to the end-effector, the single integrated shaft requires only one assembly operation, significantly reducing the number of assembling steps.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If multiple shafts are used, then the end-effector can achieve multiple rotational degrees of freedom, but the maintenance/repairing cost increases

Engineering Contradiction:
Improverotational degrees of freedomVSAvoidmaintenance/repairing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

By integrating multiple shaft functions into one component, the patent reduces maintenance cost. Instead of needing to diagnose, disassemble, and potentially replace multiple separate shafts, the maintenance personnel only need to service a single integrated shaft, reducing both time and cost for maintenance and repair operations.

Inventive Principle:
Principle #5Merging (Combining)
