Boom Component Display Apparatus for Crane Assembly Sequence Verification
Solution Overview
Problem
In crane boom assemblies composed of multiple unit booms, it is challenging to ensure that the unit booms are connected in the appropriate sequence for optimal strength and safety, as they can be assembled in various sequences due to interchangeable connecting parts.
Innovation Solution
A boom component display apparatus comprising processing units, information transmit means, and a display unit that outputs and displays identification information and connecting sequence information, allowing operators to verify the correct assembly sequence by showing the relation between unit boom identification and connecting sequence, with optional features like power source connection and memory storage for reference sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If unit booms are made with interchangeable connecting parts for multipurpose use, then adaptability and versatility are improved, but the risk of incorrect assembly sequence increases
Solution Approach 1:
The patent implements a feedback mechanism where the central control unit receives identification information from each unit boom's processing unit, determines the correct assembly sequence, and sends control signals back to guide proper assembly. This feedback loop ensures that even with interchangeable parts, the booms are assembled in the correct sequence, resolving the contradiction between versatility and reliability.
2Ease of operation
If unit booms are assembled in various sequences due to interchangeable parts, then ease of operation is improved, but manufacturing precision and assembly correctness deteriorate
Solution Approach 1:
The patent applies preliminary action by equipping each unit boom with a processing unit that contains identification information and transmitting capabilities before assembly. The central control unit预先 determines the correct assembly sequence based on this pre-loaded information, and operators simply need to follow the control signals, thus maintaining ease of operation while ensuring assembly precision.
3Measurement precision
If identification information is transmitted and displayed for each unit boom, then assembly sequence verification is improved, but device complexity increases
Solution Approach 1:
The patent employs universality by making each unit boom's processing unit multi-functional: it stores identification information, transmits this information to the central control unit, and receives control signals. This eliminates the need for separate verification devices, reducing overall system complexity while maintaining high verification accuracy.

AI summary
A boom component display apparatus 1 of the present invention is provided with processing units 4, connector assemblies 6 and a display unit 5. The processing units 4 are installed on each of a plurality of unit booms 11a thru 11g that compose a boom assembly 3 of a crane 100 and outputs identification information of each unit boom. The connector assemblies 6 transmits the identification information outputted from the processing units 4. The display unit 5 displays a connecting sequence information to show the relation between the connecting sequence of a plurality of unit booms 11a thru 11g and the identification information of a plurality of unit booms 11a thru 11g, basing on the identification information sent from the processing units 4 through the connector assemblies 6. By depending upon the boom component display apparatus of the present invention, it is possible to prevent the unit booms from being assembled in the wrong connecting sequences.
