Solution Overview

Problem

Existing lubricant dispensers with integrated electronic components and batteries are environmentally and cost-inefficient due to disposable nature and potential partial battery discharge during storage, leading to unreliable long-term operation.

Innovation Solution

The driver battery and gas-generating unit are integrated within the lubricant cartridge, with the electronic control unit lacking a power source, ensuring power is only supplied when attached, preventing pre-discharge and theft, and allowing for easy replacement of components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the battery is integrated in the lubricant cartridge, then the power supply is guaranteed for long-term operation, but the battery may be partially discharged during storage before use

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidbattery pre-discharge
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system is segmented into two separate replaceable units: a disposable lubricant cartridge containing the battery and gas generator, and a reusable electronic control unit. This segmentation allows the battery to be replaced with a fully charged one when the lubricant cartridge is replaced, eliminating pre-discharge issues during storage.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If the electronic control unit and battery are integrated in the lubricant cartridge, then the device is simpler to manufacture, but the entire cartridge must be disposed of after use, increasing environmental impact and cost

Engineering Contradiction:
Improveintegration simplicityVSAvoidelectronic component waste
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The system divides components into two segments with different lifecycles: the lubricant cartridge (consumable) and the electronic control unit (durable). The electronic control unit is detached and reused across multiple cartridges, significantly reducing electronic waste while maintaining manufacturing simplicity through standardized connection interfaces.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the battery is accessible in the lubricant dispenser, then it can be easily replaced, but it is at risk of being removed and stolen

Engineering Contradiction:
Improvebattery replaceabilityVSAvoidtheft risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The battery is merged with the disposable lubricant cartridge as a single integrated unit. When the lubricant cartridge is replaced, the battery is automatically replaced with a new one. This merging eliminates theft risk while maintaining ease of replacement, as users naturally replace the entire cartridge including the battery during routine maintenance.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If the electronic control unit has its own power source, then it can operate independently, but the battery may be partially discharged during storage and is vulnerable to theft

Engineering Contradiction:
Improveindependent operationVSAvoidstorage discharge
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The electronic control unit is designed with universal compatibility to work with multiple lubricant cartridges. It draws power from the battery in the cartridge during operation, eliminating the need for an independent power source. This multi-functional design allows the control unit to operate with any compatible cartridge while preventing storage discharge and theft.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A lubricant dispenser having a cartridge, a wall in the cartridge defining therein a lower chamber and an upper chamber, and a piston subdividing the lower chamber into a lower lubricant compartment and an upper gas compartment. The cartridge has an outlet opening into the lower lubricant compartment. A body of fluent lubricant fills the lower lubricant compartment. A housing in the upper chamber holds a gas generator connected through the wall to the gas compartment and electrically energizeable to generate gas and pressurize the gas compartment. A battery is secured to the housing. An electronic controller removably mounted in the upper chamber has electrical contacts connectable to the battery and to the gas generator. It is powerable by the battery for operating the gas generator and thereby pressurizing the gas compartment, moving the piston, and forcing the lubricant out of the outlet.
