Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional pivoting unit with arched tracks and grooves is used, then bit pivoting function is achieved, but friction is large requiring high power and producing loud noise

Engineering Contradiction:
Improvemanufacturing costVSAvoidpower consumption
Core Design Contradiction:
Ease of manufactureVSUse of energy by moving object

Solution Approach 1:

The patent replaces the conventional mechanical arched track-and-groove pivoting mechanism with a hydraulic cylinder-driven pivoting system. The hydraulic system uses fluid pressure to generate the necessary pivoting force, eliminating the high-friction mechanical contact of the arched tracks. This substitution reduces power consumption and noise while maintaining the bit pivoting function.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a hydraulic cylinder as the pivoting actuator, using hydraulic pressure to drive the pivoting motion. The hydraulic system provides smooth, controlled force application with minimal friction compared to the conventional mechanical arched track system, thereby reducing power consumption and eliminating the need for large friction-based mechanical components.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Ease of operation

If conventional pivoting unit with large friction is used, then bit pivoting is achieved, but loud noise is produced

Engineering Contradiction:
Improvebit access efficiencyVSAvoidnoise
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the noisy mechanical arched track-and-groove system with a hydraulic pivoting mechanism. The hydraulic system operates silently compared to the high-friction mechanical contact of conventional systems, eliminating loud noise while maintaining efficient bit pivoting operation through fluid-driven motion.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If high power system is used to drive conventional pivoting unit, then pivoting function is achieved, but machine tool becomes bulky

Engineering Contradiction:
Improvepivoting reliabilityVSAvoidmachine tool size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent uses a hydraulic cylinder with compact design to provide the necessary pivoting force. Hydraulic systems offer high force density, meaning substantial force can be generated in a small volume. This allows reliable bit pivoting operation without requiring a large power system, thereby keeping the overall machine tool compact and reducing its bulk.

Inventive Principle:
Principle #29Pneumatics and hydraulics

4Adaptability or versatility

If conventional chain-type bit-storing apparatus is used, then bit storage function is achieved, but manufacturing cost is high

Engineering Contradiction:
Improvebit storage capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent replaces the complex mechanical arched track-and-groove pivoting mechanism with a simpler hydraulic cylinder system. This substitution reduces the number of precision-machined components, simplifies assembly, and lowers manufacturing complexity, thereby reducing overall manufacturing cost while maintaining full bit storage and pivoting functionality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A machine tool is provided with a chain-type bit-storing apparatus which includes a frame, two sprockets, a chain and a pivoting unit. The frame includes a cutout. The sprockets are placed in the frame. The chain is driven by the sprockets. The chain includes links each including a socket for containing a bit, two plates for supporting the socket, first and second blocks placed between the plates, first and second bearing units for rotationally supporting the first and second blocks on the plates, and a connecting unit for pivotally connecting the first block thereof to the second block of an adjacent link. The pivoting unit is used to pivot the socket of a selected one of the links to move an open end of the socket out of the frame through the cutout.
