Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic systems face challenges in assembly complexity, weight, and maintenance due to heavy skeletal segments and complex one-piece tube segments, which hinder easy assembly, maintenance, and fault finding.
Innovation Solution
A robotic system with shell-like housing parts that are complementary in shape, allowing easy access and assembly, and are connected via surface contact and form-fit elements to transmit forces and torques efficiently, enabling quick assembly and maintenance while minimizing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If skeletal segments with inner support structures are used, then assembly is easy, but weight increases and torque transmission efficiency decreases
Solution Approach 1:
The housing is divided into two separate shell parts (first shell part and second shell part) that are connected together. This segmentation allows each part to be optimized for its specific function while maintaining overall structural integrity, achieving a balance between assembly ease and weight reduction by eliminating the need for heavy internal support structures.
2Weight of moving object
If one-piece tube segments are used, then weight is reduced, but assembly complexity increases and maintenance becomes difficult
Solution Approach 1:
The housing is segmented into two shell parts that can be assembled separately and then connected. This segmentation reduces the complexity of assembly compared to a one-piece design, as each shell part can be manufactured and prepared independently, and allows for easier maintenance by providing access points without requiring complete disassembly.
Solution Approach 2:
The two shell parts are designed to fit together in a nested configuration, with the first shell part containing or surrounding the second shell part. This nesting arrangement achieves compact weight reduction similar to one-piece designs while maintaining the assembly and maintenance advantages of segmented structures.
3Weight of moving object
If one-piece tube segments are used, then weight is reduced, but accessibility for maintenance becomes poor
Solution Approach 1:
The housing is divided into two accessible shell parts that can be separated or opened to provide access to internal components. This segmentation maintains the weight advantages of tube segments while dramatically improving maintenance accessibility, as technicians can access the interior space without requiring complete disassembly of the entire housing structure.
4Device complexity
If shell-like housing parts are used, then assembly is simplified and weight is reduced, but force and torque transmission capability may be compromised
Solution Approach 1:
The two shell parts are connected together to form a unified housing structure that transmits forces and torques effectively. The connection between the first and second shell parts is designed to merge their structural capabilities, creating a rigid assembly that maintains force transmission capability comparable to or better than traditional designs while retaining the advantages of simplified assembly and reduced weight.

AI summary
The present invention relates to a robotic system having at least one robot arm which consists of a plurality of members/limbs, which are connected with each other by joints, in which the housing is configured to transmit the torques and forces, which are introduced into the member, onto a member being adjacent thereto, and in which the housing is composed of at least two housing parts being complementary in shape, which housing parts are connected to each other in a manner allowing the transmission of torques and forces.
