Solution Overview

Problem

Existing tilt structures for consoles in construction machines require complex mechanisms to change the tilt of the console from outside, complicating the configuration and operation.

Innovation Solution

A tilt structure comprising a first frame, a swingable second frame, a slider, a pivotable connection member, and a control member forming a link mechanism with three turning pairs and one sliding pair, allowing simple motion to change the tilt of the console by locking or unlocking the link mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a mechanism for rotating the tilt bracket is provided to change the tilt of the console from outside, then the tilt can be adjusted, but the configuration becomes complicated

Engineering Contradiction:

Improveconsole tilt adjustmentVSAvoidmechanism configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Instead of rotating the tilt bracket from the outside to change console tilt, the invention inverts the approach by having the console itself rotate relative to the tilt bracket. The rotation mechanism is integrated into the console assembly rather than the tilt bracket, simplifying the overall configuration while achieving the same functional result of adjustable console tilt.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The invention merges the rotation function and tilt function into a unified mechanism. The console assembly includes both the rotation mechanism and the tilt bracket as integrated components, allowing both rotation and tilt adjustments to be achieved through a coordinated system rather than separate mechanisms, thereby reducing overall complexity.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If a complex mechanism is used to rotate the tilt bracket, then the tilt can be changed, but the operation becomes complicated

Engineering Contradiction:

Improvetilt adjustment capabilityVSAvoidoperation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The invention inverts which component performs the rotation - instead of the tilt bracket rotating, the console rotates on the tilt bracket. This inversion simplifies the operation because the console rotation can be directly controlled by the operator without requiring complex intermediate mechanisms, making the adjustment process more intuitive and easier to operate.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If the tilt bracket is rotated to change console tilt, then the position can be adjusted, but the configuration inside the console becomes complex

Engineering Contradiction:

Improveposition adjustmentVSAvoidinternal configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The invention inverts the rotation function from the tilt bracket to the console assembly. By making the console rotatable on the tilt bracket rather than rotating the tilt bracket itself, the internal configuration of the console is simplified. The rotation mechanism becomes part of the console's external interface with the tilt bracket, reducing the complexity of internal arrangements required to achieve position adjustment.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A tilt structure to be provided allows the tilt of a console to be changed through simple motion and has a simple configuration. A link mechanism (a mechanism similar to a slider crank mechanism) composed of three turning pairs and one sliding pair is formed using a first frame 20, a second frame 25, a slider 37, and a connection member 30. The tilt structure includes a control member 40 or 47 for fixing or unfixing the tilt of the second frame 25. The control member 40 or 47 is provided controllably in order to lock or unlock motion of the link mechanism.
