Solution Overview

Problem

Current robot waist structures require the entire waist skeleton to be replaced for design changes, leading to high costs and inefficiencies.

Innovation Solution

A modular robot waist skeleton design comprising a waist inner skeleton and a waist outer skeleton, where the outer skeleton is divided into lower, middle, and upper parts, allowing for independent replacement of the outer skeleton to change the appearance and shape without replacing the entire waist skeleton.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the entire waist skeleton is replaced to change the appearance and shape of the robot waist, then the appearance design flexibility is improved, but the manufacturing cost and complexity increase

Engineering Contradiction:
Improveappearance design flexibilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The waist skeleton is segmented into an inner skeleton and an outer skeleton. The inner skeleton maintains the movement joints and structural function, while the outer skeleton defines the appearance and shape. This segmentation allows independent replacement of the outer skeleton to achieve appearance changes without replacing the entire waist skeleton, thereby reducing manufacturing cost and complexity while maintaining design flexibility.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the entire waist skeleton is replaced to change the appearance and shape of the robot waist, then the appearance design flexibility is improved, but the time and efficiency are reduced

Engineering Contradiction:
Improveappearance design flexibilityVSAvoidreplacement time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The waist skeleton is divided into functional inner skeleton and cosmetic outer skeleton. This segmentation enables selective replacement of only the outer skeleton for appearance changes, significantly reducing replacement time and improving efficiency compared to replacing the entire waist skeleton.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the waist outer skeleton is divided into multiple parts, then the ease of replacement is improved, but the device complexity increases

Engineering Contradiction:
Improveease of replacementVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The outer skeleton is divided into multiple modular parts that can be independently assembled and replaced. This segmentation improves ease of replacement and maintenance while the modular design allows for standardized connection interfaces, minimizing the increase in structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The outer skeleton parts are designed to fit together in a nested or modular fashion around the inner skeleton, with standardized connection interfaces. This nesting approach facilitates easy assembly and disassembly for replacement while maintaining a compact and integrated overall structure, balancing ease of replacement with structural simplicity.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The present application relates to the technical field of robots, and in particular, relates to a robot waist skeleton (20) and a robot, wherein the robot waist skeleton (20) includes a waist inner skeleton (22) and a waist outer skeleton (21), surrounding the waist inner skeleton (22), the waist outer skeleton (21) being connected to the waist inner skeleton (22). According to the embodiments of the present application, when the appearance and shape of a robot waist need to be changed, only the outer skeleton (21) of the robot waist is directly replaced, with no need to wholly replace the robot waist skeleton (20), such that the cost is lowered.
