Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If direct battery connections are used in helmet mount assemblies, then power supply and data transmission are achieved, but flexibility to accommodate various battery types and power sources is limited

Engineering Contradiction:

Improveflexibility to accommodate various battery types and power sourcesVSAvoidcomplexity of connection system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter assembly serves as an intermediary device between the battery module interface and the electronic device. It includes a battery module interface that detachably couples to various battery types and a corresponding electrical connector that interfaces with the electronic device, thereby enabling flexible accommodation of different battery types without modifying the electronic device itself

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The adapter assembly is designed with a universal battery module interface that can detachably couple to multiple battery types (e.g., Li-ion, Li-polymer, NiMH) and power sources. The adapter body contains corresponding electrical connectors that maintain consistent interfacing with the electronic device, making the system multi-functional and adaptable to various power sources

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If battery packs are directly attached to helmet mount assembly, then power is provided, but seamless switching between battery packs without interrupting power cannot be achieved

Engineering Contradiction:

Improvecontinuous power supply during battery switchingVSAvoidbattery replacement process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The adapter assembly maintains continuous electrical connection with the electronic device throughout the battery switching process. The battery module interface is designed to detachably couple to one battery pack at a time while maintaining corresponding electrical connector engagement, allowing seamless battery replacement without interrupting power supply to the electronic device

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The adapter assembly automatically maintains electrical continuity during battery switching through its design. The battery module interface and corresponding electrical connector are configured so that the adapter remains engaged with the electronic device while allowing quick attachment and detachment of different battery packs, enabling the system to service itself during power transitions

Inventive Principle:

Principle #25Self-service

3Strength

If magnetic fasteners are used in adapter assembly, then secure attachment is achieved, but manufacturing precision requirements increase

Engineering Contradiction:

Improveattachment strengthVSAvoidprecision of interface alignment

Core Design Contradiction:

StrengthVSManufacturing precision

Solution Approach 1:

The adapter assembly replaces traditional mechanical fastening systems with magnetic fasteners. The battery module interface includes magnetic elements that provide secure attachment through magnetic attraction, eliminating the need for complex mechanical interlocking mechanisms and reducing manufacturing precision requirements for interface alignment

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
