Pivoting Battery Handle Cam Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery handles are difficult to assemble, often insecurely attached, and may detach during use, while flexible handles provide unstable transport due to swaying or rocking of the battery.
Innovation Solution
A pivoting battery handle with a crossbar interconnecting arms, pivotally attached to a battery cover with a cam mechanism that secures the handle in place, allowing easy assembly and secure attachment without tools, and folding for space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional pivoting battery handles are designed to pivot when not in use, then space consumption is reduced, but assembly difficulty increases requiring tools such as hand mallets, presses, or rollers
Solution Approach 1:
The handle assembly is divided into separate components: the handle body, the pivot pin, and the cam mechanism. These segments can be independently manufactured and then easily assembled together without requiring special tools, resolving the contradiction between space-saving pivot design and assembly difficulty
Solution Approach 2:
The pivot pin is inserted through a pre-formed opening in the handle, and the cam mechanism is nested within the handle structure. This nesting approach allows all components to be compactly arranged for space efficiency while maintaining simple assembly procedures without requiring mallets, presses, or rollers
2Ease of manufacture
If handles are formed of flexible members such as rope or strap, then assembly ease is improved, but transport stability deteriorates as the battery is prone to sway or rock
Solution Approach 1:
The handle material parameters are changed from flexible (rope or strap) to rigid structural material. This parameter change provides both ease of assembly through simple attachment mechanisms and transport stability by preventing battery sway and rocking during movement
3Area of stationary object
If handles are designed to pivot for space efficiency, then space consumption is reduced, but reliability deteriorates as the handle can detach while lifting or carrying the battery
Solution Approach 1:
The cam mechanism is pre-configured in the handle design to automatically engage with the battery cover during the pivoting motion. This preliminary action ensures that as the handle is rotated into its storage position, the cam automatically locks into place, preventing detachment during lifting or carrying while maintaining space efficiency in the folded position
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
The solution enables easy assembly and secure attachment of the handle to the battery, preventing detachment during use and providing stable transport by locking the handle in place, while allowing for space-saving folding when not in use.
Implementation Method 1
A cam is carried by the handle and positioned to interact with a surface on the battery cover... pivoting the handle so as to engage a cam on the handle with a surface of the recess, the cam pressing against the surface of die recess and moving the handle laterally in the recess

AI summary
A battery is disclosed. The battery includes a battery housing containing operable battery elements. A battery cover is secured to the battery housing and has a cover recess in an outer surface. A handle (48) is provided which has a crossbar interconnecting first and second arms. The handle is pivotally attached to the battery cover in the recess. The battery, handle is pivotable between a raised position relative to the battery cover and a lowered position in which the first and second arms and the crossbar are positioned within the cover recess. A cam (110) is carried by the handle and positioned to interact with a surface on the battery cover. A first mating attachment element (116) is also carried by the handle and mates with a second mating attachment element carried by the battery cover. A battery handle and a method of attaching a handle to a battery cover are also disclosed.
