Angular Strut Anti-Twist Design for Concrete Pump Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing truck-mounted concrete pumps face challenges in using struts as carriers for additional components due to the lack of anti-twist protection with round tubes, limiting the attachment of further parts without connecting both struts.
Innovation Solution
The use of struts with an angular cross-section, featuring twist-proof fork heads and fastening clips, allows for secure mounting of additional components without the risk of unintentional rotation, enabling the strut to function as a holder for various parts like grease tanks, mast rests, and hydraulic pipe holders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If round tubes are used as struts, then the struts can be made slimmer and lighter, but screw clamps cannot be easily implemented due to lack of anti-twist protection
Solution Approach 1:
The strut cross-section is changed from a symmetric round shape to an asymmetric angular shape. This asymmetry provides inherent anti-twist protection and creates flat surfaces that facilitate the attachment of components using screw clamps, resolving the contradiction between weight reduction and component attachment capability.
Solution Approach 2:
The angular cross-section of the strut provides localized flat surfaces at specific positions, creating optimal areas for component attachment. This local quality enhancement allows screw clamps to be effectively used without requiring the entire strut to be redesigned, maintaining weight efficiency while improving adaptability.
2Adaptability or versatility
If struts are used as carriers for additional components, then the functionality of the pump is enhanced, but the struts require additional attachment options which increases complexity
Solution Approach 1:
The angular cross-section of the strut serves itself by providing inherent anti-twist protection and convenient attachment surfaces. The strut's own geometric features enable component attachment without requiring additional specialized attachment mechanisms, thereby enhancing functionality while avoiding increased complexity.
Solution Approach 2:
The angular strut design serves multiple functions simultaneously: it provides structural support, prevents twisting, and enables component attachment through its flat surfaces. This multi-functionality reduces the need for separate attachment systems, enhancing versatility without proportionally increasing complexity.
3Reliability
If both struts are connected to attach components, then anti-twist protection is achieved, but the attachment process becomes more complex
Solution Approach 1:
The asymmetric angular cross-section provides inherent anti-twist protection through its geometric shape itself, eliminating the need to connect both struts for this purpose. The flat surfaces of the angular section allow component attachment using standard screw clamps on a single strut, simplifying the attachment process while maintaining reliability.
