Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw locking method is used to combine the clamp body and jaw, then the jaw can be securely fixed, but the jaw replacement requires a screwdriver which reduces user convenience and increases operation time
Solution Approach 1:
The locking mechanism is segmented into multiple functional components: a bolt with threaded portion, a rod, and an operating lever. This segmentation allows each component to perform its specific function while working together to achieve both secure fixation and easy operation. The bolt provides the locking force, the rod transmits motion, and the lever provides mechanical advantage for easy manipulation.
Solution Approach 2:
The locking mechanism is designed to be self-operating through the operating lever that the user can directly manipulate. The lever's movement automatically drives the rod and bolt to lock or unlock the jaw without requiring any external tools. The spring-loaded design allows the bolt to self-adjust and maintain secure fixation while enabling tool-free operation for jaw replacement.
2Reliability
If a screw locking method is used to combine the clamp body and jaw, then the jaw can be securely fixed, but the jaw replacement process becomes time-consuming
Solution Approach 1:
The locking mechanism transitions from a static screw connection to a dynamic lever-operated system. The operating lever can be quickly moved between locked and unlocked positions, enabling rapid jaw replacement. The spring-loaded bolt dynamically adjusts to maintain secure fixation during normal use while allowing swift release when the lever is actuated, thus improving jaw replacement speed without compromising fixation security.
Solution Approach 2:
The bolt is pre-positioned within the clamp body with its threaded portion aligned with the jaw's threaded hole. The spring maintains the bolt in a ready-to-lock position. When the operating lever is actuated, the preliminary alignment and spring force enable immediate locking or unlocking action, significantly reducing the time required for jaw replacement while ensuring reliable fixation.

AI summary
A crimping clamp includes a pair of clamp bodies, a pair of jaws and a pair of lock mechanisms. A head end of the clamp body includes a containing groove, a pair of perforations and at least one opening. The perforations are respectively disposed at two corresponding sides of the containing groove and correspond to each other. Each of the jaws includes a hole. When each of the jaws is combined in each containing groove, each hole corresponds to one of the openings. Each of the lock mechanisms includes a bolt, a rod and an operating lever. The bolt is movably inserted in the opening. One end of the rod is connected with one end of the bolt. The operating lever is movably inserted in the perforation, and one end of the operating lever is connected with the other end of the rod.
