Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In robot devices with parallel links, the arrangement of multiple speed reducers coaxially on a base part with integrally formed flanges complicates the processing and coupling of these flanges due to tool limitations, making it difficult to handle the increased number of flanges and maintain structural integrity.
Innovation Solution
The use of adapter components to simplify the processing of flanges on the base part, allowing for the coupling of multiple speed reducers with a reduced number of components, by strategically arranging and processing the flanges to accommodate the speed reducers in a compact and efficient manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple flanges are integrally formed on a base part to arrange speed reducers in parallel, then the structural integrity is maintained, but the processing difficulty increases due to tool access limitations
Solution Approach 1:
The base part is divided into multiple separable flange components that can be processed independently and then assembled together. This segmentation allows each flange to be accessed and processed by standard tools without the complexity of machining multiple flanges simultaneously on a single integral structure, while still achieving the desired structural integrity through proper assembly and fastening of the segmented flanges to the base part.
2Adaptability or versatility
If three hollow flanges are arranged in parallel with long distance between outer and innermost flanges, then the speed reducers can be accommodated, but the processing becomes difficult due to tool strength restrictions
Solution Approach 1:
Instead of arranging flanges in a linear parallel configuration that requires long-distance tool access, the flanges are positioned to utilize three-dimensional space more efficiently. The adapter components are designed with a compact geometry that allows flanges to be arranged in a configuration accessible from multiple directions, reducing the maximum tool reach required while still accommodating the necessary speed reducers.
3Volume of moving object
If two small-sized speed reducers are arranged to sandwich the first arm, then the joint size is reduced, but the number of flanges and coupling components increases
Solution Approach 1:
Multiple flange interfaces and coupling functions are merged into integrated adapter components. Each adapter component combines the flange structure with mounting features and coupling mechanisms, so that instead of requiring separate components for each flange and coupling element, a single integrated adapter performs multiple functions. This reduces the total component count while maintaining the compact joint structure achieved by sandwiching the first arm between two small-sized speed reducers.

AI summary
A robot device simplifies processing of flanges integrated with a base part, making it possible to use a small number of adapter components to connect corresponding decelerators to the processed flanges. The base part houses decelerators that drive a first arm and a second arm that have a parallel link. Two first decelerators are arranged on either side of the first arm so as to be parallel and drive the first arm. A second decelerator is arranged parallel to the two first decelerators and drives the second arm. Two first adaptor components are respectively arranged between the base part and the two first decelerators and connect the base part and the first decelerators; and a second adapter component is arranged between the base part and the second decelerator and connects the base part and the second decelerator.
