Battery Holder Isolation Assembly Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles' batteries often fail prematurely due to excessive vibrations and shocks, and existing solutions are costly and difficult to replace or dispose of safely, especially in harsh environments like marine and off-road applications.
Innovation Solution
A battery holder and isolation assembly that secures the battery to a vehicle while mechanically isolating it from vibrations and shocks, using a combination of jackets, mats, and fasteners to absorb and dissipate forces, and accommodate various battery sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is directly mounted to the vehicle, then the mounting structure is simple, but the battery is exposed to excessive vibrations and shocks causing premature failure
Solution Approach 1:
The patent introduces a battery holder assembly as an intermediary component between the battery and vehicle mounting surface. This assembly includes vibration isolation elements (rubber pads, foam materials) and structural components (jacket, top plate, retainer bracket) that mediate the connection, absorbing vibrations and shocks while securing the battery. The intermediary structure protects the battery from direct exposure to vehicle vibrations without requiring complex integration into the vehicle itself.
Solution Approach 2:
The patent applies beforehand cushioning by incorporating vibration isolation elements (rubber pads, foam materials) into the battery holder assembly before the battery is subjected to vibrations and shocks. These cushioning elements are pre-positioned between the battery/jacket and the mounting surface to absorb and dampen vibrations and shocks before they can damage the battery, thereby extending battery life in harsh environments.
2Reliability
If a protective assembly is used to isolate the battery, then the battery is protected from vibrations and shocks, but the assembly becomes more difficult to replace and dispose
Solution Approach 1:
The patent divides the protective assembly into distinct, separable segments: the jacket that receives the battery, the top plate that encloses the battery, and the retainer bracket that secures the assembly to the vehicle. These segmented components can be independently removed and reinstalled, allowing the battery to be accessed and replaced by simply removing the top plate and retainer bracket, rather than dealing with a monolithic difficult-to-disassemble structure.
Solution Approach 2:
The patent incorporates dynamic fastening mechanisms including threaded fasteners with locking features and releaseable retainer brackets that can be quickly engaged and disengaged. The retainer bracket includes features that allow it to be securely fastened during operation but easily released when replacement is needed, providing dynamic adaptability between the protected state during use and the easily replaceable state when maintenance is required.
3Manufacturing precision
If the battery holder is designed to fit specific battery sizes, then the fit is precise, but the holder cannot accommodate different battery sizes and shapes
Solution Approach 1:
The patent designs the jacket and top plate as universal components with adjustable dimensions and configurations that can accommodate multiple battery sizes and shapes. The jacket includes adjustable sidewalls and the top plate includes adjustable openings, allowing the same holder assembly to fit different battery types (e.g., Group 24, Group 27, Group 31) while maintaining precise fit and protection. This multi-functional design eliminates the need for multiple specialized holders for different battery sizes.
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 effectively prolongs battery life by protecting it from external shocks and vibrations, allowing for easier replacement and disposal, while being adaptable to different battery sizes and shapes, thus enhancing durability and safety.
Implementation Method 1
The lower mat absorbs shocks and vibrations and is placed under the battery on a battery mounting surface, mounting bracket, or other surface. The lower mat may be at least partially formed of any shock-absorbing material such as rubber, gel, or foam
Implementation Method 2
The lower mat may include a number of openings extending therethrough for allowing the lower mat to bulge outward and stretch inward under compression and tension forces

AI summary
A battery holder comprises a jacket, an upper plate, and a retainer bracket. The jacket forms an open-topped chamber and includes an upper outwardly extending lip. The upper plate and the retainer bracket are fastened to the upper lip for securing a battery in the open-topped chamber. Another embodiment of the battery holder comprises a lower mat, an upper mat, and a strap. The lower mat and the upper mat include at least one pad formed of shock-absorbing material and having a number of openings for allowing the pad to bulge outwardly and flex inwardly. Another embodiment of the battery holder comprises a lower mat and a number of clips. The lower mat includes a shock absorbing pad. The clips secure a battery to the lower mat and include a number of slits for preventing the battery from sliding.
