Assembly Cartridge for Bar Clamp Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of multiple component devices, such as bar clamps, is challenging due to the complexity of components, lack of open access, and the need to assemble springs under tension or compression, making it difficult to assemble efficiently on the main assembly line.
Innovation Solution
A separate cartridge with an open framework is used to define component locations and facilitate access during assembly, allowing the cartridge and its components to be assembled off the main assembly line, then inserted into the device housing for completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If components are assembled directly in the clamp housing on the main assembly line, then the device can be assembled in one location, but the assembly process becomes difficult due to lack of open access and component complexity
Solution Approach 1:
The clamp assembly is divided into two main segments: the housing and the cartridge. The cartridge contains all the complex drive and brake mechanisms, separating them from the housing assembly. This segmentation allows the cartridge to be assembled separately in a controlled environment with proper access, while the housing remains simple for final assembly.
Solution Approach 2:
The cartridge serves as an intermediary component that encapsulates the complex drive and brake mechanisms. By introducing this intermediate assembly unit, the patent simplifies the overall assembly process while maintaining all necessary functional components within a manageable, pre-assembled package.
2Productivity
If all components are assembled on the main assembly line, then integration is simplified, but productivity decreases due to assembly difficulties
Solution Approach 1:
The cartridge and its components are assembled in advance, off the main assembly line, in a dedicated setup that provides optimal access and lighting. This preliminary assembly of the complex cartridge portion eliminates time-consuming on-line assembly operations and increases overall productivity.
3Reliability
If springs are assembled under tension and/or compression, then the drive and brake mechanism can function properly, but the assembly process becomes more difficult
Solution Approach 1:
The spring-loaded drive and brake mechanisms are extracted from the housing and placed within the cartridge. This extraction allows springs to be installed in the cartridge under controlled tension and compression conditions, ensuring proper functionality while simplifying the overall assembly process through the cartridge's modular design.

AI summary
The assembly method of the invention uses a cartridge that is separate from the housing of the device being manufactured. The cartridge is configured such that the location of the various components is defined and the components are easily accessed. The cartridge and its components may be assembled off of the main assembly line. Once the cartridge is assembled, the cartridge and assembled components can be placed in the housing. The assembly of the device can then be completed.
