Trolley for carrying goods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Replacing a large pool of trolleys with millions of shelves and posts is complex and costly, especially when inferior quality items are introduced, complicating logistics and requiring time-consuming processes.
Innovation Solution
The trolley design features hooks extending in a lateral direction and posts with specific openings, allowing for easy modification and reuse of existing posts, with shelves being the primary replacement component, ensuring compatibility and simplifying logistics by preventing old shelves from being used in the new pool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large pool of trolleys with millions of shelves and posts is replaced, then quality standards can be improved, but replacement costs and logistics complexity increase significantly
Solution Approach 1:
The system is segmented into three distinct components: posts, shelves, and trolleys. The invention allows selective replacement of only the shelf component while maintaining compatibility with existing posts and trolleys. This segmentation enables quality improvement of shelves without requiring complete pool replacement, thereby reducing logistics complexity and costs.
Solution Approach 2:
The post design with lateral openings and the shelf design with corresponding hooks create a universal connection system. The posts can accommodate different shelf types through the lateral openings, and the trolleys can work with various shelf configurations. This universality allows quality-improved shelves to be integrated into the existing pool without requiring replacement of other components.
2Quantity of substance
If inferior quality items are introduced to avoid hiring shelves, then costs are reduced, but logistics are complicated and require time-consuming processes
Solution Approach 1:
The invention applies local quality by making only the shelf component replaceable and upgradeable, while maintaining the existing posts and trolleys. This allows selective improvement of shelf quality without requiring complete pool replacement, enabling quality standards to be raised without proportionally increasing replacement costs or time investment.
Solution Approach 2:
The lateral opening configuration in posts and the corresponding hook design in shelves represent parameter changes that enable easy assembly and replacement. These parameter modifications allow for quick interchange of shelves, reducing the time required for pool maintenance and quality improvements compared to traditional integrated designs.
3Ease of operation
If hooks extend in longitudinal direction, then shelves can be easily attached to posts, but old shelves can be used in the new pool defeating the purpose of replacement
Solution Approach 1:
The invention introduces asymmetry by positioning the openings laterally on the posts rather than symmetrically on all sides. The hooks on shelves are designed to engage specifically with these laterally positioned openings. This asymmetric configuration maintains ease of attachment while preventing old shelves with different hook orientations from being used in the new pool, ensuring replacement effectiveness.
Solution Approach 2:
The invention transitions from traditional longitudinal hook engagement to lateral opening engagement, effectively changing the dimension of connection. The openings are positioned on the lateral sides of posts rather than on the longitudinal faces, creating a new engagement dimension that maintains operational ease while ensuring compatibility only with newly designed shelves.

AI summary
A trolley comprising a plurality of rectangular and elongated shelves comprising a plate providing a surface for carrying goods, such as potted plants and flowers, and hooks, and a plurality of posts provided with a series of openings, such as slots, receiving the hooks. The hooks extend in lateral direction and a series of openings is provided in precisely one side of the posts or in precisely two and opposite sides of the posts.
