Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If conventional lead acid battery jump starters are used, then power output is sufficient for heavy duty applications, but weight becomes extremely high (hundreds of pounds) and portability is lost

Engineering Contradiction:

Improvepower outputVSAvoidweight

Core Design Contradiction:

PowerVSWeight of moving object

Solution Approach 1:

The patent changes the chemical parameters of the battery system by using lithium-ion battery chemistry instead of conventional lead acid chemistry. This fundamental parameter change enables achieving high power output (capable of jump starting heavy duty vehicles) while dramatically reducing weight, thereby resolving the contradiction between power and portability

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs composite construction by combining lithium-ion battery cells with a conductive frame structure made of highly electrically conductive materials. This composite approach optimizes both power delivery capability and weight characteristics, allowing the device to maintain high power output while minimizing weight for portability

Inventive Principle:

Principle #40Composite materials

2Reliability

If battery cables are permanently attached to the jump starter, then electrical connectivity is ensured, but weight and size increase and portability decreases

Engineering Contradiction:

Improveelectrical connectivityVSAvoidweight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent segments the jump starter system into separate modular components: the main jump starter device and detachable battery cables. The cam-lock connectors enable reliable electrical connection when cables are attached, but allow the cables to be separated and stored separately, reducing the weight that must be carried during transportation while maintaining reliability when needed

Inventive Principle:

Principle #1Segmentation

3Power

If high power output is achieved for effective jump starting, then jump starting capability is sufficient for big engines, but device size becomes large requiring fork lift for movement

Engineering Contradiction:

Improvepower outputVSAvoidsize

Core Design Contradiction:

PowerVSVolume of moving object

Solution Approach 1:

The patent changes the energy density parameter by adopting lithium-ion battery technology, which provides significantly higher energy and power density per unit volume compared to conventional lead acid batteries. This enables achieving high power output for jump starting big engines while dramatically reducing the device volume, making it portable without requiring industrial equipment like fork lifts for movement

Inventive Principle:

Principle #35Parameter changes

4Weight of moving object

If detachable cable connectors are used to reduce weight, then portability is improved, but connection reliability and power handling capability may be compromised

Engineering Contradiction:

ImproveweightVSAvoidconnection reliability

Core Design Contradiction:

Weight of moving objectVSReliability

Solution Approach 1:

The patent extracts the cable connection function into separate detachable cam-lock connectors that can be attached or removed as needed. These connectors are designed with robust construction to maintain high connection reliability and power handling capability when attached, while allowing the cables to be separated and stored separately to reduce carrying weight, thus resolving the contradiction between portability and connection reliability
