Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a conventional electronic bicycle safety locking system is used, then the system can provide automated locking and recording functions, but the system becomes unreliable during power outages and prone to human error
Solution Approach 1:
The locking system is divided into independent mechanical locking members (first locking member with positioning convex, second locking member with blocker, third locking member with guider) that can function independently of the electronic control system. Each locking member operates through dedicated displacement paths that can be mechanically controlled without power, ensuring reliability during power outages while maintaining automated control capability when powered.
Solution Approach 2:
The locking mechanism incorporates self-servicing features through spring-based reset forces that automatically return locking members to their initial positions after operation. The mechanical components self-regulate their movement through defined displacement paths and limiting tracks, eliminating the need for external power or complex electronic control during basic locking operations.
2Adaptability or versatility
If a conventional electronic locking system with many complicated structures for electronic records and managements is used, then the system can provide comprehensive management functions, but managing the system becomes difficult
Solution Approach 1:
The essential locking function is extracted from the complex electronic management system and implemented through simple mechanical components. The locking mechanism uses basic mechanical elements (locking members, displacement limiters, springs) that can be managed independently of the electronic record-keeping system, reducing overall system complexity while maintaining management capabilities.
Solution Approach 2:
The mechanical locking mechanism is designed to be universally applicable to different bicycle types through standardized mounting on the bicycle frame. The same basic locking structure can serve multiple functions: securing the bicycle, providing mechanical backup during power outages, and operating independently of electronic systems, thereby simplifying management across diverse bicycle fleets.
3Reliability
If the locking mechanism uses multiple locking members with displacement paths, then the locking reliability is improved, but the device complexity increases
Solution Approach 1:
The locking members are nested within a compact locking mechanism structure where the first, second, and third locking members are arranged in sequence along the bicycle frame. Each locking member operates within its own defined displacement path but shares common mounting structures and control elements, reducing overall spatial requirements and structural complexity while maintaining multi-stage locking reliability.
Solution Approach 2:
The locking mechanism incorporates dynamic elements including springs that provide reset forces to return locking members to their initial positions. The displacement paths allow locking members to move dynamically between locked and unlocked states, with the third locking member extendably controlled by the control module to adapt to different locking conditions, thereby achieving reliable locking without excessive structural complexity.

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 device ensures secure locking and unlocking of bicycles during power outages and reduces the risk of human error, providing a reliable and versatile solution for different bicycle types by using a combination of spring forces and sensor integration for effective operation.
Implementation Method 1
The first locking member has a reset force and is telescopically located and limited at the locking groove along a wheel axis of the bicycle
Implementation Method 2
The reciprocating displacement limiter has a reset force and is located at the bicycle locking mechanism, and the reciprocating displacement limiter corresponds with the lock-in part and can open or close a displacement path of the lock-in part
Implementation Method 3
the reset force of the reciprocating displacement limiter is a spring or a force of gravity
Implementation Method 4
The second locking member has a reset force and is telescopically located and limited at the locking groove along the axis
Implementation Method 5
The third locking member has a push surface that reciprocally pushes the reciprocating displacement limiter
