Removable Motorcycle Stand Handle with Tapered Interlock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle stands lack the ability to easily reconfigure and compactly store or ship, as their handles are not designed to serve as structural elements after use and are limited in orientation options.
Innovation Solution
A removable handle system using male and female mating members with a screw fastener, allowing for forward or rearward orientation and serving as a structural part, with tapered surfaces for interlocking and rotational stability, enabling easy removal and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the handle is made removable for reconfiguration and storage, then adaptability and storage efficiency are improved, but structural strength and reliability deteriorate
Solution Approach 1:
The handle is divided into two separate components: a handle body and a mating member. The mating member can be removed from the main chassis, allowing the handle to be reconfigured or stored separately, while the segmented design maintains structural integrity when assembled
Solution Approach 2:
Tapered surfaces are pre-formed on the mating members before assembly. These tapered surfaces automatically guide and align the components during insertion, ensuring proper positioning and maximizing structural strength before the fastening operation begins
2Ease of operation
If the handle is made removable for reconfiguration, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The fastening function is extracted from the handle design and implemented using a standard screw fastener. This separates the removable mating member from the fastening mechanism, allowing easy removal and installation using common tools while avoiding complex integrated fastening systems
Solution Approach 2:
The mating members feature asymmetric tapered surfaces with specific geometric profiles. This asymmetric design provides intuitive alignment during assembly, ensuring the components mate in the correct orientation while simplifying the user operation through natural guidance
3Stability of the object's composition
If tapered surfaces are used for interlocking, then stability and rotational resistance are improved, but manufacturing precision requirements increase
Solution Approach 1:
The tapered surfaces are designed with specific geometric parameters (angle, length, profile) that optimize both stability and manufacturability. By carefully selecting these parameters, the design achieves high rotational stability while remaining compatible with standard manufacturing processes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the motorcycle stand to be reconfigured for different orientations, used as a structural element, and compactly stored or shipped, enhancing user convenience and space efficiency.
Implementation Method 1
A screw is used to apply lateral force to keep the male and female members mated
Implementation Method 2
Mating tapered (conical) surfaces are also used to interlock the male and female laterally and rotationally

AI summary
A removable handle for a motorcycle stand that can be removed/replaced to face forward or rearward and on left or right side of motorcycle. When installed the handle is indexed at a precise angle to provide the correct angle for lifting the motorcycle. The handle is capable of being removed easily by removal of a single screw and when installed it is held tight by virtue of the mating male/female members that contain a star-shaped key section, a tapered/conical section and a cylindrical section. When the handle is removed from the motorcycle stand it is compact for shipping and/or storage.
