Swap Body Locking Head for Longitudinal Guide Immobilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for immobilizing and securing swap bodies are ineffective for models with longitudinal or few transverse crossmembers, as they rely on detecting transverse crosspieces, which are absent in newer designs, leading to instability and accident risks during loading and unloading.
Innovation Solution
A device with a head featuring lateral arms equipped with anti-slip pads and a wide detection plate to secure both longitudinal and transverse crossmembers, along with retractable locking tabs, ensures universal compatibility and stability, using a steel structure with a hydraulic cylinder to actuate the arms for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detection means has a small width to detect transverse crosspieces, then the device can effectively lock bodies with transverse crossmembers, but it cannot detect or lock bodies with longitudinal or few transverse crossmembers
Solution Approach 1:
The detection means is designed with a width of at least 90 mm to serve multiple functions: it can detect both transverse crosspieces (when present) and longitudinal crossmembers (when present), making the device compatible with various body configurations including those with only longitudinal crossmembers
Solution Approach 2:
The locking function is divided into two independent systems: detection means (wide plate at least 90 mm wide) for locating the body center, and locking means (lateral arms with locking pads) for securing the body. This segmentation allows each component to be optimized for its specific function while working together to handle diverse body types
2Ease of operation
If the device uses traditional transverse crossbar detection, then it can secure bodies with standard crossmember configurations, but it fails to secure bodies without or with few transverse crossmembers
Solution Approach 1:
The lateral arms are designed to perform dual functions: they can lock onto transverse crosspieces when present, and alternatively lock onto longitudinal crossmembers or guides when transverse crosspieces are absent, making the device universally applicable to various body configurations
Solution Approach 2:
The lateral arms are movable rather than fixed, allowing them to dynamically adjust their position and locking point based on the body configuration. This dynamic capability enables the arms to engage with different structural elements (transverse crosspieces, longitudinal crossmembers, or guides) depending on what is available
3Adaptability or versatility
If the detection plate is made wide (at least 90 mm) to detect longitudinal crossmembers, then the device can locate bodies without transverse crosspieces, but the detection system becomes more complex
Solution Approach 1:
The detection function and centering function are merged into a single wide detection plate (at least 90 mm wide). This unified component simultaneously detects the presence of longitudinal crossmembers and centers the device on the body, eliminating the need for separate detection and centering mechanisms

AI summary
A locking device head (1) secures a mobile crate (15) unloaded from the truck. This head (1) is positioned on the locking and securing device, which slides under the crate (15) and immobilizes it by blocking its underside. The head comprises a metal structure supporting at least one means for detecting the underside of the crate (15) and locking means (3a, 3b, 10a, 10b) for the crate (15). The locking means consist of at least two lateral arms (3a, 3b) extending symmetrically from the metal structure (2) until they rest on the guides (18) of the crate (15). Each arm (3a, 3b) is equipped with an anti-slip pad (6a, 6b) to support the corresponding guide (18). The head (1) further includes retractable cleats (10a, 10b) oriented upwards to retract or block the transverse cross members (17) of the body (15).
