A jointing structure featuring a jointing member with multiple abutting members disposed on its side surfaces, allowing for secure engagement with various forcing tools and torque measuring devices, ensuring accurate torque measurement and transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional jointing structure is used, then the device complexity is low, but the engagement tightness between forcing tools and torque measuring devices is poor

Engineering Contradiction:

Improveengagement tightnessVSAvoidjointing structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The jointing structure is divided into multiple abutting members (first, second, third, and fourth abutting members) disposed on different side surfaces of the jointing body. Each abutting member independently engages with corresponding forcing tools, distributing the engagement function across multiple segmented elements rather than a single monolithic structure, thereby improving engagement tightness while maintaining manageable complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The abutting members are integrated within the jointing body structure, with each abutting member positioned on a specific side surface. The forcing tools are nested within the jointing structure through these abutting members, creating a hierarchical engagement system where tools are held securely by the nested abutting members, enhancing engagement reliability.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Measurement precision

If a conventional jointing structure is used, then the manufacturing process is simple, but the torque measurement precision is inaccurate

Engineering Contradiction:

Improvetorque measurement accuracyVSAvoidjointing structure fabrication

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

Different abutting members are positioned on different side surfaces of the jointing body, with each abutting member optimized for its specific location and engagement function. The first and second abutting members engage one type of forcing tool, while the third and fourth abutting members engage another type, providing locally optimized engagement quality for accurate torque measurement across different tool configurations.

Inventive Principle:

Principle #3Local quality

3Force

If a conventional jointing structure is used, then the device design is simple, but the force transmission effectiveness is poor

Engineering Contradiction:

Improveforce transmissionVSAvoidjointing structure design

Core Design Contradiction:

ForceVSDevice complexity

Solution Approach 1:

Multiple abutting members are combined within a single jointing body, with each abutting member contributing to the overall force transmission. The first, second, third, and fourth abutting members work together to securely hold forcing tools and transmit force effectively to the torque measuring device, merging multiple engagement functions into one integrated jointing structure.

Inventive Principle:

Principle #5Merging (Combining)
