Foldable Garden Shredder With Rotating Support for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional garden shredding apparatuses are bulky and inconvenient to transport and store due to their excessive height and size, with issues such as occluded particle outlets, interference between components during retraction, and compromised usability when batteries are removed for size reduction.
Innovation Solution
A shredding apparatus with a shredder assembly that rotates about a first axis within an open space in the support assembly, allowing for a compact internal layout and reducing overall size in the retracted state, featuring a frame assembly with a chassis and support portion, and a particle discharging section that avoids interference, along with a detachable particle collection bag and hanger system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the shredder assembly is made foldable and retractable into the collection bin, then the bulkiness disadvantage is partially overcome, but the particle outlet opening becomes occluded by the collecting section
Solution Approach 1:
The shredder assembly is divided into separable components including the shredder body, collection bin, and support portion. The shredder body can be detached from the collection bin, allowing the particle outlet to remain unoccluded while the collection bin is stored separately, thus resolving the contradiction between compact storage and discharge functionality.
Solution Approach 2:
The shredder assembly incorporates a rotatable connection between the shredder body and support portion, enabling dynamic adjustment between operating position and retracted position. This rotational mechanism allows the particle outlet to be positioned away from the collecting section during operation, preventing occlusion while maintaining compact dimensions when retracted.
2Stability of the object's composition
If the shredder assembly is fixed to the opposite end of the support portion to lock the retracted state, then the retracted state is locked, but interference occurs between the shredder assembly and the frame structure during rotation
Solution Approach 1:
The locking function is extracted from the frame structure and implemented as a separate locking mechanism that engages with the shredder assembly. This allows the shredder assembly to rotate freely within the open space without interfering with the frame structure, while still achieving a locked retracted state through the dedicated locking mechanism.
Solution Approach 2:
A locking mechanism acts as an intermediary between the shredder assembly and the support portion. This intermediary component enables the locked retracted state without requiring direct fixation to the frame structure, thereby preventing collision and interference during the rotation process.
3Volume of moving object
If the battery is removed to reduce the overall size of the retracted shredder assembly, then the compact layout and reduced size are achieved, but use convenience is significantly compromised
Solution Approach 1:
The power system is segmented into a removable battery pack that can be detached from the shredder assembly. This allows the battery to be stored separately when not in use, reducing the overall size of the retracted assembly, while maintaining full functionality and convenience during operation when the battery is installed.
Solution Approach 2:
The battery installation is designed as a dynamic, tool-free attachment process that allows quick installation and removal. This enables the battery to be easily attached when needed for operation and detached for compact storage, resolving the contradiction between size reduction and operational convenience.
