Robot Shaft Unit Modular Adjustment Mechanism

Solution Overview

Problem

Existing robots require disassembly and reassembly of the second shaft unit to change the operating range, which is time-consuming and increases component count and costs.

Innovation Solution

A robot design featuring a detachable securing member between the second and third members of the second shaft unit, allowing the operating range to be adjusted by shifting the second shaft unit without disassembly, using flat plate members for securing and reducing component complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the second shaft unit is disassembled and reassembled to change the operating range, then the operating range can be adjusted, but the adjustment process becomes time-consuming and complex

Engineering Contradiction:

Improveoperating range adjustmentVSAvoidadjustment time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The robot arm is divided into modular sections (first shaft unit, second shaft unit) that can be independently adjusted. The securing member allows each module to be quickly repositioned without disassembling the entire structure, enabling rapid operating range changes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The securing member provides a dynamic adjustment mechanism that allows the second shaft unit to be quickly repositioned along the first shaft unit. This dynamic positioning capability enables rapid adaptation of the operating range without time-consuming disassembly and reassembly operations.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the second shaft unit is disassembled and reassembled to change the operating range, then the operating range can be adjusted, but the device complexity increases

Engineering Contradiction:

Improveoperating range adjustmentVSAvoidassembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The robot arm is divided into modular sections (first shaft unit, second shaft unit) that can be independently adjusted. The securing member allows each module to be quickly repositioned without disassembling the entire structure, enabling rapid operating range changes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The securing member serves multiple functions: it connects the first and second shaft units, allows for rapid positioning, and maintains structural integrity. This multi-functional component simplifies the overall device complexity while enabling operating range adjustment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If traditional disassembly methods are used to adjust the operating range, then the range can be changed, but the cost increases

Engineering Contradiction:

Improveoperating range adjustmentVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The securing member provides a dynamic adjustment mechanism that allows the second shaft unit to be quickly repositioned along the first shaft unit. This dynamic positioning capability enables rapid adaptation of the operating range without time-consuming disassembly and reassembly operations.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:
