Solution Overview

Problem

The flexibility of conductive parts in shielded connector units leads to tilting issues during assembly, necessitating manual support or jigs, which complicates the workability of connecting upper and lower shielded connectors.

Innovation Solution

A shielded connector unit design featuring a hard protector with an interference part at its lower portion to prevent excessive tilting, ensuring the conductive parts and upper connectors remain stable by interfering with the instrument's support, eliminating the need for manual or jig-based support during assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If flexible conductive parts are used to connect lower and upper shielded connectors, then the connectors can be connected at different positions, but the conductive parts and upper connectors may tilt during assembly, requiring manual support or jigs

Engineering Contradiction:
Improveability to connect at different positionsVSAvoidworkability during assembly
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The protector is designed with an interference part that proactively prevents tilting by interfering with the support on the first instrument or shielding shell before tilting can occur. This preliminary anti-action eliminates the need for manual support during assembly while maintaining the flexibility needed for connecting at different positions.

Inventive Principle:
Principle #9Preliminary anti-action

2Stability of the object's composition

If manual support or jigs are used to prevent tilting during assembly, then tilting can be controlled, but the workability and assembly process become more complex

Engineering Contradiction:
Improvecontrol of tiltingVSAvoidassembly process complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The protector is designed to automatically prevent tilting through its own structure - the interference part on the protector works with the support on the first instrument or shielding shell to self-regulate the position of the conductive parts and upper connectors during assembly, eliminating the need for external jigs or manual support.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the conductive parts are made flexible to allow movement, then connection flexibility is improved, but excessive tilting occurs during assembly

Engineering Contradiction:
Improveconnection flexibilityVSAvoidtilting control
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The protector provides localized stability at specific points - the interference part creates a localized constraint that prevents excessive tilting at critical positions during assembly, while the rest of the conductive parts maintain their flexibility for connection at different positions. This local quality approach balances flexibility and stability.

Inventive Principle:
Principle #3Local quality

AI summary

A shielded connector unit includes a lower shielded connector to be connected downwards to a lower positioned first instrument, an upper shielded connector to be connected sideways to a second instrument positioned above the first instrument, and a flexible conductive part made up of an electric wire which is adapted to connect the lower shielded connector to the upper shielded connector and a braid which is adapted to enclose a bare portion of the electric wire existing between a shielding shell of the lower shielded connector and a shielding shell of the upper shielded connector. The shielded connector unit further includes a hard protector that is adapted to enclose and protect the conductive part from the outside while ensuring flexibility of at least a portion of the conductive part.
