Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional battery post terminals are used with separate nuts and fastening components, then the assembly can be manufactured, but the assembly process becomes time-consuming and labor-intensive

Engineering Contradiction:
Improveassembly speedVSAvoidnumber of fastening components
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate fastening components (post, nut, and fastening mechanism) into a single integrated battery post terminal assembly. The terminal incorporates a built-in fastening mechanism that eliminates the need for separate nuts and fastening components, thereby reducing assembly time and increasing productivity while maintaining structural integrity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The battery post terminal assembly is designed to perform multiple functions: it provides electrical connection (terminal function) and mechanical fastening (fastening mechanism) in a single component. This multi-functionality reduces the number of parts needed and simplifies the assembly process, directly addressing the productivity issue.

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

2Reliability

If multiple separate components are used for battery post terminals, then manufacturing flexibility is maintained, but the risk of corrosion and structural failure increases

Engineering Contradiction:
Improvecorrosion resistanceVSAvoidnumber of connection points
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

By integrating the fastening mechanism directly into the terminal structure, the patent reduces the number of connection points where corrosion could occur. The single integrated assembly minimizes exposed surfaces and potential failure points compared to multiple separate components, thereby improving reliability and corrosion resistance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The terminal assembly utilizes composite construction with a polymer body and metal fastening elements, creating a structure that combines the corrosion resistance of polymers with the mechanical strength of metals. This composite approach enhances overall reliability while reducing susceptibility to galvanic corrosion between dissimilar metals.

Inventive Principle:
Principle #40Composite materials

3Strength

If complex fastening mechanisms are used to ensure secure connections, then connection strength is improved, but manufacturing cost and complexity increase

Engineering Contradiction:
Improveconnection strengthVSAvoidfastening mechanism complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The integration of the fastening mechanism into the terminal body allows for optimized connection strength without adding external complexity. The unified structure enables direct load paths and efficient force distribution, achieving strong connections while keeping the overall design simple and manufacturable.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A battery post terminal assembly includes a conductive band and a clamp mechanism. The conductive band includes a first free end and a second free end. The conductive band defines an aperture for receiving a battery post of a battery. The clamp mechanism includes a wedge member that defines a recess between a first surface and a second surface thereof. The recess has an open end and a closed end that is narrower than the open end. The first surface is convex. The first free end and the second free end are positioned in the recess. The first free end is movable along the first surface toward the closed end to be moved by the first surface toward the second free end to tighten the conductive band around the battery post.
