Engineering Contradiction:
Improveassembly task capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent merges multiple tool functions into a single integrated tool assembly on one carriage, reducing the total number of manufacturing robots required. This consolidation directly lowers equipment costs, installation costs, and maintenance costs while preserving the capability to perform complex assembly tasks.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The universal tool assembly design allows a single carriage to handle multiple assembly operations with different tools, replacing multiple expensive specialized robots. The modular tool configuration enables flexibility in performing various assembly tasks without additional equipment investment.

3Device complexity

If carriages are restricted to single-axis movement, then the system design is simplified, but the manufacturing process flexibility is limited

Engineering Contradiction:
Improvesystem design simplicityVSAvoidprocess flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamic capabilities to the carriage by enabling rotational movement of the tool assembly and individual tools relative to the carriage body. This allows tools to be oriented in different directions and perform operations from multiple angles, providing process flexibility while maintaining the simple single-axis translation of the carriage itself.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent adds rotational degrees of freedom to the tool assembly, allowing tools to move from the single-axis linear motion of the carriage into additional rotational dimensions. This enables complex assembly operations requiring multi-axis tool positioning without complicating the underlying carriage guide rail system.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
