Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly apparatuses face challenges in securely gripping and positioning components for assembly, particularly in ensuring a stable and efficient transfer of components without requiring motive power, which can lead to damage or high costs.
Innovation Solution
A gripping mechanism comprising a rolling body, a frame, and a downward pushing section, where the frame houses the rolling body and utilizes a spring-based downward pushing mechanism to grip components between the rolling body and the frame, leveraging friction and gravity for secure holding without the need for motive power, allowing for stable conveyance and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If an electric gripping mechanism is used, then the gripping force can be controlled, but the device complexity and cost increase
Solution Approach 1:
The patent replaces electric gripping mechanisms with a purely mechanical spring-based system. The elastic member (spring) provides the gripping force through its elastic deformation, eliminating the need for motors, sensors, and control systems while achieving reliable gripping of components
Solution Approach 2:
The spring-based gripping mechanism is self-actuating and requires no external power source. The elastic member automatically generates gripping force through its inherent elasticity, and the system self-regulates the gripping pressure based on the spring's mechanical properties without requiring external control
2Reliability
If air suction or electric suction is used, then gripping can be achieved, but the reliability decreases due to potential damage and higher costs
Solution Approach 1:
The patent replaces suction-based gripping (pneumatic or electric) with direct mechanical contact gripping using a spring and roller. This mechanical approach provides more reliable and controllable gripping force that can be precisely adjusted by spring selection, eliminating the unpredictable nature of suction-based systems
Solution Approach 2:
The patent enables easy adjustment of gripping parameters by simply exchanging springs with different elastic coefficients. This allows optimization of gripping force for different component types and weights, improving reliability without changing the overall mechanism structure
3Adaptability or versatility
If a spring-based downward pushing mechanism is used, then the gripping force can be adjusted, but the device complexity increases
Solution Approach 1:
The patent achieves gripping force adjustment by changing the elastic coefficient of the spring through simple component exchange. This modifies the gripping parameter without altering the mechanism structure, providing versatility while maintaining simplicity
Solution Approach 2:
The spring-based mechanism serves multiple functions: it provides gripping force, positions the component vertically, and absorbs positioning errors. This multi-functionality is achieved through a single simple mechanical element rather than multiple complex subsystems

AI summary
A gripping mechanism includes a holder, a gripping roller, and a downward pushing section. The holder houses the gripping roller. The downward pushing section pushes downward on an object gripped between the holder and the gripping roller. Preferably, the downward pushing section has a first downward pushing mechanism, a second downward pushing mechanism, and a third downward pushing mechanism. The first downward pushing mechanism protrudes from a ceiling surface among inner surfaces of the holder. The second downward pushing mechanism and the third downward pushing mechanism protrude from respective surfaces opposite to the object among outer surfaces of the holder.
