Roller Pallet Push Handle With Detachable Spring Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller pallets are limited in manual manipulation, especially when transporting loads without a suitable surface for manual action, and lack flexibility for both manual and motorized transport options.
Innovation Solution
A push handle with a rigid or foldable design, featuring a U-shaped handle and two pivotably connected fixing legs with plug-in pins and a spring clip for detachable attachment to the base, allowing for easy handling and adaptation to different transport methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the roller pallet is designed with fixed handle and push handle for manual manipulation, then manual transport capability is improved, but motorized transport capability deteriorates
Solution Approach 1:
The handle and push handle are designed to be foldable and detachable, allowing the structure to dynamically change from an extended operational state to a compact stored state. This enables the roller pallet to adapt between manual transport mode (handles extended) and motorized transport mode (handles folded or detached)
2Stability of the object's composition
If the push handle is made rigid and fixed to the base, then structural stability is improved, but ease of detachment and adaptability deteriorates
Solution Approach 1:
The push handle is segmented into multiple components: the hand grip portion, the fixing leg with plug-in pin, and the spring clip. This segmentation allows the handle to be assembled and disassembled in simple steps while maintaining structural stability when connected
Solution Approach 2:
The spring clip automatically engages with the base structure when the plug-in pin is inserted, providing self-locking functionality. This eliminates the need for complex fastening mechanisms while ensuring stable attachment during use
3Ease of operation
If the fixing leg is designed with simple plug-in pin for easy attachment, then ease of operation is improved, but reliability of attachment deteriorates
Solution Approach 1:
The spring clip acts as an intermediary component between the plug-in pin and the base structure. It provides a simple mechanical interaction for the user (pushing the pin) while simultaneously creating a reliable locked connection through the spring's elastic engagement with the base

AI summary
The invention relates to a rolling pallet equipped with a base (1) arranged mostly horizontally and with wheels (2, 3) attached to the underside of the base (1). At least two wheels (3) are each designed to pivot about a mostly vertical axis. Furthermore, at least one bracket (4, 5) extending mostly vertically and arranged on the base (1) is provided. According to the invention, the bracket (4, 5) is designed as an L-shaped push bar (4, 5) that can be detachably attached to the base (1) in side view (S).
