Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current capping machines lack operational flexibility in adjusting axial loads for different screw cap types, requiring complex and time-consuming processes, especially when integrated springs are used, and are costly when dedicated capping heads are needed for each type.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-loaded compression springs are integrated into the motion transmission group, then the axial load can be applied during vertical translation, but the adjustment becomes operationally complex and time-consuming
Solution Approach 1:
The motion transmission group is divided into separable modules: the first module contains the compression spring, while the second module can be quickly coupled or uncoupled from the first. This segmentation allows the spring-containing module to be replaced as a complete unit rather than requiring complex in-situ adjustment, significantly reducing operational time while maintaining the pre-loaded spring mechanism's functional benefits.
Solution Approach 2:
The system transitions from a static, fixed spring configuration to a dynamic, interchangeable module system. The motion transmission group can be reconfigured by coupling different modules with different pre-loaded springs according to different cap types, enabling rapid adaptation without complex adjustment procedures.
2Adaptability or versatility
If dedicated capping heads are provided for each cap type, then operational flexibility is improved, but system cost increases
Solution Approach 1:
A single capping head design is made universal by combining it with interchangeable motion transmission modules. Each module is configured with specific pre-loaded springs for different cap types, allowing one capping head to perform multiple functions across different cap types without requiring dedicated heads for each type, thereby reducing overall system complexity and cost.
Solution Approach 2:
The motion transmission modules are pre-configured with appropriate compression springs for specific cap types before being installed on the capping head. This preliminary preparation allows for rapid switching between cap types by simply replacing the pre-configured module rather than adjusting a single complex mechanism, enhancing adaptability while maintaining simplicity.
3Adaptability or versatility
If frequent cap changes are required, then production flexibility is needed, but specialized personnel and equipment are required for spring replacement
Solution Approach 1:
The system is designed to enable operators to perform module replacements without requiring specialized personnel or equipment. The coupling mechanism between modules is simplified to allow straightforward attachment and detachment of spring-containing modules, making the system self-sufficient for routine changes and eliminating the need for specialized intervention.
Solution Approach 2:
By segmenting the motion transmission group into replaceable modules, the complex task of spring replacement is transformed into a simple module swap operation. This segmentation isolates the complex spring mechanism within a self-contained module that can be handled and replaced by standard operators using basic tools or even hand operations.
