Foldable Grass Mower Collection Box with Rotating Support Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grass mower collection boxes are bulky, making them inconvenient for transportation and storage due to their large size, which is necessary for increased capacity but results in excessive space occupation.
Innovation Solution
A foldable collection box design featuring support assemblies with rotating upper and lower arm portions, an adaptation groove, and a clamping groove, allowing the box to be compactly folded for storage, reducing occupied space and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the collection box is designed as big as possible to enlarge collection capacity, then the collection capacity is improved, but the occupied space increases causing inconvenience to transportation and collection
Solution Approach 1:
The collection box employs a foldable structure with support assemblies that allow the box to transition between an expanded state during operation (maximizing collection capacity) and a collapsed state for storage and transportation (minimizing occupied space). The upper and lower arm portions can rotate relative to each other, enabling dynamic volume adjustment.
Solution Approach 2:
When collapsed, the collection box structure nests within itself, with the bottom plate and side edge portions folding inward toward the upper cover. This nesting arrangement significantly reduces the volume occupied by the collection box during storage and transportation while maintaining full collection capacity when deployed.
2Quantity of substance
If the collection box is designed as big as possible to enlarge collection capacity, then the collection capacity is improved, but the weight increases causing inconvenience to transportation and collection
Solution Approach 1:
The foldable support assemblies allow the collection box to achieve large collection capacity during operation without requiring a permanently large structure. When collapsed for transportation, the weight is concentrated in a compact form, making it easier to handle and transport compared to a permanently large rigid box.
Solution Approach 2:
The collection box is divided into modular components including the upper cover, bottom plate, side edge portions, and support assemblies. This segmentation allows the structure to achieve large volume when assembled for use while maintaining lower overall weight through efficient material distribution and the ability to collapse components together during storage.
3Volume of moving object
If the collection box is made foldable with support assemblies, then the occupied space is reduced, but the device complexity increases
Solution Approach 1:
The support assemblies incorporate rotating joints between upper and lower arm portions that enable the foldable functionality. These rotating mechanisms provide the necessary movement for collapsing and expanding the collection box while maintaining a relatively simple structural design that does not overly complicate the overall device.
Solution Approach 2:
The support assemblies integrate multiple functions into single components, combining structural support, folding capability, and connection between the upper cover and bottom plate. This merging of functions reduces the number of separate parts needed and simplifies the overall structure despite the added foldable functionality.

AI summary
A foldable gardening tool collection box comprises an upper cover (31), a bottom plate (33), side edge portions (34), and support assemblies (35). The support assemblies (35) are disposed between the upper cover (31) and the bottom plate (33). The support assembly (35) comprises an upper arm portion (351), a lower arm portion (352), and a rotating portion (36). The upper arm portion (351) and the lower arm portion (352) can rotate oppositely around a rotary shaft (A) through the rotating portion (36). The collection box (3) at least comprises two support assemblies (35). The support assemblies (35) are disposed on the collection box (3), so that the collection box (3) having the support assemblies (35) can be folded to be stored, and occupied space of the collection box (3) is greatly reduced; meanwhile, the support assembly (35) has a simple structure and has a small number of parts, and the weight of the collection box (3) is reduced.
