Problem

The manufacturing of ion traps made from nonconductive bulk material with electrical connections is complicated, leading to longer production times and potential defects due to the need for additional steps and processes.

Innovation Solution

A monolithic trap module with a spring element made from a non-conductive substrate, featuring a conductive area connected to an electrode, allows for electrical connections through compression, eliminating the need for separate connection methods like wire-bonding or soldering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wire-bonding, soldering, or separate connectors are used to create electrical connections on ion traps, then electrical connectivity is achieved, but manufacturing complexity increases and production time extends

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidmanufacturing process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the electrical connection function directly into the trap body by forming conductive areas on the nonconductive substrate that serves as both the structural body and the electrical connection interface. This eliminates the need for separate connectors, wire-bonding, or soldering steps, thereby reducing manufacturing complexity while maintaining reliable electrical connectivity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The nonconductive substrate serves multiple functions: it provides the structural body of the ion trap, supports the electrodes, and simultaneously provides the electrical connection interface through formed conductive areas. This multi-functionality reduces the number of separate components needed and simplifies the overall manufacturing process.

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

2Reliability

If separate connection methods like wire-bonding or soldering are used, then electrical connections are established, but production time increases

Engineering Contradiction:
Improveelectrical connection stabilityVSAvoidproduction speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The electrical connection structure is integrated into the trap body formation process itself. Conductive areas are formed directly on the nonconductive substrate during the same manufacturing steps used to create the trap structure, eliminating sequential operations like wire-bonding or soldering that would extend production time.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The conductive areas are prepared in advance as part of the substrate processing before final assembly. This preliminary formation of connection interfaces ensures that electrical connectivity is already established when components are assembled, eliminating time-consuming post-assembly connection steps.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If multiple manufacturing steps are added to create electrical connections, then connectivity is achieved, but the risk of defects increases

Engineering Contradiction:
Improveelectrical connection qualityVSAvoidproduction defect rate
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

By combining the electrical connection formation with the trap body fabrication process, the patent reduces the total number of manufacturing steps. Fewer discrete steps mean fewer opportunities for defects to occur during assembly, handling, or joining operations, thereby improving overall manufacturing precision.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The nonconductive substrate itself serves as the foundation for electrical connections through formed conductive areas, eliminating the need for separate connection components that would require additional assembly steps. This self-integrated approach reduces handling and assembly operations that could introduce defects.

Inventive Principle:
Principle #25Self-service
