Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable connectors with thermally welded reinforcing plates face issues with cable peeling due to torque applied during flexible cable connections, and they are not easily removable or mountable on receptacles.
Innovation Solution
An adapter for cable connectors featuring a pair of operation portions with guide pins, a protection portion, and a reinforcing portion, along with a lock spring mechanism, which securely holds the cable end portion and prevents peeling, while allowing easy mounting and dismounting from a receptacle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reinforcing plate is thermally welded to the cable end using adhesives, then the cable can be electrically connected, but the cable may peel from the reinforcing plate when torque is applied
Solution Approach 1:
The adapter is divided into multiple functional segments: a reinforcing plate for thermal welding to the cable, a body portion for receiving the cable end, guide pins for positioning, and operation portions for insertion/removal. This segmentation allows each part to specialize in resisting specific forces, with the reinforcing plate handling thermal welding bonds and the body portion handling mechanical torque resistance through its structured geometry.
Solution Approach 2:
The adapter combines multiple materials with complementary properties: the reinforcing plate uses thermally weldable material for strong cable bonding, while the body portion uses rigid material resistant to peeling forces. This composite structure integrates the advantages of different materials to simultaneously achieve strong cable attachment and peeling resistance.
2Device complexity
If the male connector is simply connected by thermally welding the reinforcing plate, then the structure is simple, but the cable secured by adhesives may be peeled under torque
Solution Approach 1:
The adapter merges multiple functions into a single integrated component: the reinforcing plate for thermal welding, the body portion for cable reception and positioning, guide pins for alignment, and operation portions for manual handling. This unified structure provides both structural simplicity and enhanced peeling resistance compared to separate components.
Solution Approach 2:
The adapter extends the connection structure from a simple flat plate to a three-dimensional body portion with vertical walls and internal cavities. This dimensional expansion creates multiple surfaces for adhesive bonding and mechanical interlocking, significantly increasing resistance to peeling forces while maintaining reasonable structural complexity.
3Strength
If the cable connector is designed for secure cable fixation, then peeling is prevented, but ease of mounting and dismounting on receptacle is reduced
Solution Approach 1:
The adapter incorporates operation portions that enable dynamic insertion and removal actions. These portions are designed with appropriate geometry and flexibility to allow the adapter to be easily pushed onto and pulled off the receptacle, while the reinforced body portion maintains strong cable fixation during normal use. The structure transitions from a static rigid form to one that accommodates operational dynamics.
4Manufacturing precision
If guide pins are added for precise positioning, then mounting accuracy is improved, but device complexity increases
Solution Approach 1:
The guide pins are integrated as protrusions directly formed on the body portion of the adapter, merging the positioning function into the main structure rather than being separate components. This integration provides precise positioning guidance during receptacle mounting while avoiding the complexity of additional detachable parts.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adapter effectively secures the cable by forming a stationary surface that prevents peeling under applied forces and facilitates easy mounting and dismounting, ensuring stable electrical connections.
Implementation Method 1
The male connector formed on the cable side is conventionally formed by thermally welding a reinforcing plate made of an electric insulating synthetic resin on one surface of the cable end portion using adhesives

AI summary
An adapter for a cable connector secured with a cable end portion to make the electrical connection by being removably mounted on a receptacle of the cable connector includes a pair of operation portions, a pair of guide pins integrally formed in front of the operation portions and each having a pointed end portion at the front, a protection portion for connecting the operation portions at the rear lower part, a connection portion for connecting the operation portions at the front upper part, and a reinforcing portion for connecting the pair of guide pins, wherein the protection portion and the connection portion have an interval in the longitudinal and vertical directions and are disposed in parallel to each other, and the lower surfaces of the connection portion and the reinforcing portion are continuous flush to form a stationary surface for securing the cable end portion.
