Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex assembly process of robots, particularly the precise alignment of rotary axes in multiple assemblies, makes the integration of warehouses and maintenance work challenging, leading to difficult and time-consuming assembly procedures.
Innovation Solution
A robot design featuring a first assembly with a storage that includes a first fastening element, allowing the second assembly to be movable and easily assembled using complementary fastening elements, which ensures precise positioning and alignment without the need for elaborate alignment procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bearings are inserted and installed during assembly, then the robot assemblies can be connected, but the assembly process becomes complex with many individual parts that must be precisely aligned
Solution Approach 1:
The patent combines the bearing and the fastening element into a single integrated component. The bearing is designed with an integrated fastening element that directly connects to the complementary fastening element on the second assembly, eliminating the need for separate bearing installation and reducing the number of individual parts that must be aligned during assembly.
Solution Approach 2:
The bearing is pre-integrated into the first assembly with the fastening element already in position. This preliminary integration means that during final assembly, the bearing does not need to be separately installed and aligned - it is already positioned correctly as part of the first assembly, simplifying the assembly process.
2Ease of manufacture
If bearings are permanently integrated into one assembly, then assembly is simplified, but very precise relative positioning and alignment of rotation axes is required
Solution Approach 1:
The fastening elements are designed to be self-aligning during assembly. The complementary shapes of the fastening elements automatically guide the assemblies into the correct relative position and alignment as they are joined, eliminating the need for external alignment procedures or highly precise pre-positioning of the assemblies.
Solution Approach 2:
The fastening elements have asymmetric, complementary shapes that provide built-in alignment features. These asymmetric geometries ensure that the assemblies can only be joined in the correct orientation, automatically achieving precise alignment of rotation axes without requiring external alignment tools or procedures.
3Productivity
If complementary fastening elements are used, then assembly is simple and rapid, but the bearing must be pre-integrated into the assembly
Solution Approach 1:
The bearing and fastening element are merged into a single integrated component. This combination allows the bearing to be pre-integrated into the assembly without adding separate fastening components, enabling simple and rapid assembly through the complementary fastening elements while avoiding the complexity of multiple separate parts.
