Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB connectors lack a direction adjustment mechanism, leading to entanglement, cable distortion, and instability due to fixed direction connections, which can result in wire breakage and dislocation.
Innovation Solution
A USB connector with a rotating mechanism comprising a top cover, connector seat, cable slot, cable rotating seat, and bottom cover, featuring a pivot slot and positioning holes, allowing the connector to rotate 180 degrees and maintain cable orientation, preventing twisting and ensuring stable signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed direction mechanism is used to connect the cable to the USB connector, then the structure is simple, but the connectors and cables become entangled and the cable cannot restore to its original shape after distortion
Solution Approach 1:
The patent applies the dynamics principle by introducing a rotating mechanism that allows the connector to change its orientation dynamically. The connector can rotate 180 degrees around a pivot axis, transforming from a fixed static structure to a dynamic one that adapts to different cable positions. This resolves the contradiction by maintaining structural simplicity while enabling cable flexibility and preventing entanglement.
Solution Approach 2:
The patent segments the connector into distinct functional components: a rotating seat that pivots, a positioning mechanism with multiple positioning holes, and a cable guide structure. This segmentation allows each component to perform its specific function - the rotating seat provides motion, the positioning holes provide stable positions, and the cable guide prevents entanglement - while maintaining overall structural simplicity.
2Reliability
If the cable is constantly pulled and twisted, then the connector becomes dislocated, but adding a rotation mechanism increases device complexity
Solution Approach 1:
The rotating mechanism with pivot axis and positioning holes provides controlled mobility that actually enhances stability. The connector can dynamically adjust to pulling forces through rotation rather than dislocation, and the multiple positioning holes ensure it settles into stable positions. This dynamic stability prevents dislocation without requiring complex locking mechanisms.
Solution Approach 2:
The rotating seat acts as an intermediary between the cable and the connector body. It absorbs and accommodates pulling and twisting forces through controlled rotation around the pivot axis, preventing these forces from directly dislocating the connector. This intermediary mechanism protects the connection stability while maintaining simple overall structure.
3Adaptability or versatility
If the connector is restricted to a fixed direction, then the structure is simple, but the USB connector cannot adapt to different cable arrangements
Solution Approach 1:
The connector achieves adaptability through dynamic rotation capability. The rotating seat allows the connector to orient itself in different directions (0度和180度positions) based on cable arrangement, transforming a fixed-direction connector into an adaptive one. This dynamic adaptation is achieved with minimal additional structure - primarily the pivot axis and positioning mechanism.
4Strength
If the cable is distorted or twisted, then it cannot restore to original shape and wires may break, but preventing rotation increases cable stress
Solution Approach 1:
The rotating mechanism provides controlled movement that prevents uncontrolled cable distortion. By allowing the connector to rotate smoothly around the pivot axis, the cable can move without twisting or bending excessively. The positioning holes provide stable stopping points that prevent over-rotation, protecting the cable from damage while maintaining operational flexibility.
Solution Approach 2:
The rotating seat serves as an intermediary that decouples cable movement from wire stress. When the cable moves, the rotation absorbs the motion rather than transmitting it as twisting stress to the wires inside. This protective function maintains cable durability while allowing necessary cable movement and positioning flexibility.
