Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If drilling holes and using bolts with nuts or welding devices are used to attach grounding connectors to metal structures, then reliable electrical bonding is achieved, but the process becomes time-consuming and costly

Engineering Contradiction:
Improveelectrical bonding reliabilityVSAvoidbonding process time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The bonding connector is divided into separate components: a body portion with gripping members for attaching to the metal structure, and a cap portion with a fastener receiving member. This segmentation allows the connector to be attached using simple manual fastening rather than requiring drilling or welding equipment, significantly reducing installation time while maintaining reliable electrical bonding through the conductive path between the body and cap portions.

Inventive Principle:
Principle #1Segmentation

2Reliability

If drilling holes and using bolts with nuts or welding devices are used to attach grounding connectors to metal structures, then reliable electrical bonding is achieved, but the cost increases

Engineering Contradiction:
Improveelectrical bonding reliabilityVSAvoidbonding process cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention extracts the need for complex drilling and welding equipment by using a pre-formed bonding connector with integrated gripping members. The connector is designed to attach to metal structures through simple mechanical fastening with a fastener received in the fastener receiving member, eliminating the need for expensive power tools and specialized welding equipment, thereby reducing overall bonding process costs while maintaining reliable electrical connection.

3Strength

If heavy power tools like drills or welding devices are used to attach connectors, then secure attachment is achieved, but the equipment becomes heavy and cumbersome

Engineering Contradiction:
Improveattachment strengthVSAvoidequipment weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The bonding connector is designed with self-service characteristics where the body portion's gripping members directly engage with the metal structure, and the cap portion receives a simple fastener to secure the connection. This design eliminates the need for heavy external power tools or welding equipment, allowing the connector to achieve secure attachment through its own structural features and simple manual fastening, thereby dramatically reducing equipment weight and complexity.

Inventive Principle:
Principle #25Self-service
