Chain Clamp Device for Multi-Position Hoisting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for lifting equipment to elevated positions are inefficient, as they can only be attached to the bottom of a chain, require multiple operations for multiple items, are complex to assemble, and are not versatile for use with ropes or cables.
Innovation Solution
A clamp device with a body member and door member, featuring eyelets, projection members for chain engagement, and a locking mechanism, allowing attachment at any chain link and secure hoisting, as well as a version for ropes/cables with a clamping mechanism, enabling efficient and versatile lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing devices are attached only to the bottom of a chain, then the device structure is simple, but multiple hoisting operations are required for multiple items and the burden on the hoisting device is high
Solution Approach 1:
The clamp device is designed to attach to any link along the chain rather than only the bottom link, enabling multiple items to be hoisted simultaneously in a single operation. This multi-position attachment capability transforms the device from a single-point attachment tool to a multi-point attachment system, dramatically improving hoisting efficiency without significantly increasing device complexity
Solution Approach 2:
The device incorporates a movable jaw with spring-loaded engagement mechanisms that can dynamically adapt to different chain link positions. The spring-loaded design allows the clamp to self-adjust and securely engage with chain links at various positions along the chain, enabling flexible multi-position attachment while maintaining simple device construction
2Device complexity
If existing devices have only one hook attached to the lower end portion, then the device structure is simple, but multiple hoisting operations are required for multiple items
Solution Approach 1:
The clamp device enables simultaneous attachment of multiple items at different chain positions, transforming the hoisting process from sequential single-item operations to parallel multi-item operations. This eliminates the time loss associated with multiple separate hoisting operations while maintaining reasonable device structural simplicity through the use of standardized clamp mechanisms at each attachment point
Solution Approach 2:
Multiple clamp devices can be pre-attached to different positions along the chain before the hoisting operation begins. This preliminary positioning allows all items to be ready for simultaneous lifting, eliminating the need for sequential attachment operations and reducing total hoisting time without adding complex assembly procedures
3Reliability
If existing devices require a wrench and other hardware such as screws and nuts for assembly, then the attachment is secure, but the assembly process is complicated and hardware is easily lost
Solution Approach 1:
The design extracts and eliminates the need for separate fastening hardware such as screws, nuts, and wrenches by integrating the attachment function directly into the clamp mechanism itself. The self-contained clamp design achieves secure attachment through its inherent mechanical structure rather than relying on separate fastening components, simplifying assembly and preventing hardware loss
Solution Approach 2:
The clamp device is designed to be self-assembling and self-securing without requiring external tools or additional hardware. The spring-loaded engagement mechanisms and movable jaw design allow the device to automatically secure itself to the chain link through simple manual operation, eliminating the need for wrenches, screws, and nuts while maintaining reliable attachment
4Adaptability or versatility
If existing devices are designed only for steel chain, then the device structure is specialized, but the device cannot be used with rope, cable, or other cord type members
Solution Approach 1:
The clamp device is designed with a universal attachment mechanism that can securely engage with multiple types of hoisting members including steel chains, ropes, cables, and cord-type members. The movable jaw and spring-loaded engagement system can adapt to different geometries and materials, providing versatile compatibility across various hoisting applications without requiring multiple specialized devices
Solution Approach 2:
The device incorporates adjustable parameters such as movable jaw positioning and spring pressure that can be modified to accommodate different hoisting member types. By changing these parameters, the same basic device structure can effectively engage with chains, ropes, cables, and other materials, achieving versatility without increasing fundamental device complexity
