Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lift truck attachments with scales reduce the lifting capacity and make removal and repair difficult due to redundant parts and complex sensor arrangements.
Innovation Solution
A lift truck attachment system with a carriage-mounted scale and integrated sensors, utilizing rails, plates, and mounting brackets to measure load without significant loss in lifting capacity, allowing easy installation, removal, and repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional attachments with scales are added to a standard carriage, then load measurement capability is improved, but lift capacity is reduced and device complexity increases
Solution Approach 1:
The patent combines the scale attachment and sensor mounting functions into a single integrated carriage-mounted scale assembly. The sensor is directly mounted on the carriage structure at the interface between the carriage and scale, eliminating the need for separate sensor attachments and redundant mounting components. This merging approach provides load measurement capability while maintaining lift capacity and reducing overall device complexity.
2Measurement precision
If additional attachments with scales are added to a standard carriage, then load measurement capability is improved, but lift capacity is reduced
Solution Approach 1:
The patent extracts only the essential sensor mounting function from traditional scale attachments, eliminating redundant structural components. By mounting the sensor directly on the carriage at the load interface and using a minimal mounting bracket system, the design achieves load measurement capability with minimal additional weight, thereby preserving maximum lift capacity.
3Measurement precision
If traditional scale attachments are used, then load measurement is achieved, but removal and repair become difficult
Solution Approach 1:
The patent segments the scale system into modular components: the carriage-mounted scale assembly, the sensor, and the mounting bracket. This segmentation allows the sensor to be easily removed and replaced independently from the scale assembly, and the mounting bracket can be quickly detached from the carriage. This modular design significantly improves ease of repair and maintenance while maintaining load measurement capability.
