Gate Lock Lever Guide Structure for Adjustable Machine Consoles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction machines face challenges in maintaining operability of the gate lock lever when the height position of the control lever is adjusted relative to the operator's seat, leading to discomfort and reduced usability for operators of varying physiques.
Innovation Solution
A construction machine with a console device featuring a rotational frame and a height adjusting mechanism, where a guide member with a guide groove restricts the movement of the gate lock lever's shaft body, ensuring the gripping part remains consistent despite adjustments to the control lever's height position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a construction machine is disassembled into multiple components for transport, then transportability is improved, but reassembly requires high technical knowledge and time consumption
Solution Approach 1:
The construction machine is divided into multiple detachable components including boom, arm, bucket, counterweight, and track assembly. Each component can be independently transported and stored, enabling flexible deployment and reducing transport volume requirements.
Solution Approach 2:
Connection parts are pre-equipped with identification markers and guide structures that indicate the correct assembly sequence and orientation. Technical information including assembly instructions and identification data are stored in advance in storage units attached to each component, allowing operators to quickly locate and assemble parts without requiring extensive technical knowledge.
2Ease of operation
If connection parts are designed for easy assembly, then ease of operation is improved, but connection strength may be compromised
Solution Approach 1:
Connection parts incorporate intermediate elements such as pins, bolts, and locking mechanisms that mediate between the simple assembly operation and the strong mechanical connection. These intermediaries transfer and distribute loads while maintaining ease of attachment and detachment through standardized interfaces.
Solution Approach 2:
The connection system utilizes parameter changes in the form of identification markers and guide structures that change the assembly process from complex technical judgment to simple visual matching. The markers provide visual feedback that confirms proper alignment and connection, ensuring strength without requiring operator expertise.
3Measurement precision
If technical information is provided in detailed manuals, then measurement precision is improved, but ease of operation deteriorates due to complexity
Solution Approach 1:
Critical technical information including assembly instructions, identification data, and assembly sequence is extracted from comprehensive manuals and embedded directly into storage units attached to each component. This allows operators to access only the specific information needed for the current assembly task, eliminating the need to consult complex manuals while maintaining assembly precision.
Solution Approach 2:
Identification markers use visual indicators such as colored codes, patterns, or illuminated displays that provide immediate visual feedback about component identity and correct assembly orientation. This visual information system replaces text-heavy manuals with intuitive color-coded or symbol-based guidance that maintains precision while dramatically improving ease of operation.

AI summary
A left console device (13) positioned on an entrance passage (9A)-side is provided with a support shaft (15) disposed on a seat base (11), and a rotational frame (17) rotatably supported by the support shaft (15) . A gate lock lever (25) is provided with a base plate (25A) that is rotatably supported via a first shaft body (17D) on the rotational frame (17) and in which a second shaft body (25D) is disposed, and a lever member (25B) that is provided with a gripping part (25E) and is disposed to be integral with the base plate (25A). A guide plate (26) is rotatably attached to a seat base (11). A guide groove (27) disposed on the guide plate (26) restricts a movement of the second shaft body (25D) to suppress a change in a height position of the gripping pin (25E) of the lever member (25B) when the rotational frame (17) rotates centering on the support shaft (15) together with the gate lock lever (25) .
