Battery-Powered Grease Tank Design for Fewer Replacements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grease discharge devices for heavy machinery have limited grease storage capacity, requiring frequent cartridge replacements and restricting mobility due to the need for a power supply cord and air hose.
Innovation Solution
A grease discharge device with a grounded-type tank capable of storing 10 liters or more of grease, equipped with a pump unit driven by an attachable and detachable battery, allowing for increased storage and improved mobility without the need for a power supply cord or air hose.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a battery-driven portable grease discharge device with small grease storage is used, then ease of handling and mobility are improved, but the frequency of cartridge replacement increases
Solution Approach 1:
The device is divided into separable components: a removable battery unit and a grease storage tank. This allows the battery to be detached and recharged independently while the grease tank can be refilled or replaced separately, reducing downtime and maintaining portability despite larger grease capacity.
2Adaptability or versatility
If a battery-driven portable grease discharge device is used, then mobility and work area flexibility are improved, but power supply reliability is reduced due to battery limitations
Solution Approach 1:
The battery is designed to be detachable and replaceable, transforming from a fixed power source to a dynamic one. This allows the battery to be recharged or replaced on-site without returning to a base station, maintaining continuous operation capability and reliability while preserving mobility and work area flexibility.
3Loss of time
If a large grease storage tank is used, then the frequency of replacement is reduced, but weight and portability are worsened
Solution Approach 1:
The grease storage tank is designed as a separate removable component from the battery unit. This segmentation allows the tank to be optimized for larger capacity without proportionally increasing the weight of the powered unit, as the battery can be detached and the tank refilled or replaced independently, maintaining overall portability while reducing replacement frequency.
4Reliability
If conventional grease discharge devices with power supply cord and air hose are used, then power supply reliability is improved, but ease of handling and mobility are reduced
Solution Approach 1:
The power supply cord and air hose connections are completely removed from the system. The battery is extracted as an independent portable power source, eliminating the need for external power supply infrastructure. This extraction maintains sufficient power supply reliability for grease discharge operations while completely restoring full mobility and ease of handling to the device.
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 provides a significant increase in grease storage capacity, reducing the frequency of replacements and enhancing mobility by eliminating the need for power and air hoses, thereby improving ease of handling and work area flexibility.
Implementation Method 1
The pump unit is connected to the lid and configured to suction the grease in the tank and discharge the grease to an outside of the tank by driving of a motor
Implementation Method 2
The attachable and detachable battery drives the motor
Data Source
AI summary
A grease discharge device includes a grounded-type tank, a lid, a pump unit, and an attachable and detachable battery. The grounded-type tank is configured to store grease with an opening at an upper part of the tank. The lid closes the opening. The pump unit is connected to the lid. The pump unit suctions the grease in the tank and discharges the grease to an outside of the tank by driving of a motor. The attachable and detachable battery drives the motor.
