Solution Overview
Problem
Existing alignment devices for bicycles and similar vehicles lack precision and ease in aligning components such as brake levers and gearshift levers, particularly when these components are mirror-symmetrical, and often require insecure attachment methods.
Innovation Solution
An alignment device with a swivel arm and laser, featuring a vehicle coupling with a rotary bearing device, allowing secure attachment to the vehicle and enabling precise alignment of components through rotational and tilting adjustments, using a locking mechanism to fix the swivel arm in position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual alignment methods are used, then the alignment process is simple, but the alignment precision is insufficient
Solution Approach 1:
The patent replaces manual visual alignment with an optical measurement system using a laser that projects reference lines and points. The laser alignment device provides precise optical references that eliminate the imprecision of eye-based alignment while maintaining operational simplicity through intuitive visual cues.
Solution Approach 2:
The patent introduces a laser as an intermediary tool between the alignment device and the vehicle components. The laser projects visible reference lines and points that serve as mediators, allowing the user to accurately align brake levers, gear levers, and other components without direct mechanical contact or complex measurement procedures.
2Measurement precision
If the pivot arm is made adjustable for precise alignment, then alignment precision improves, but the device complexity increases
Solution Approach 1:
The patent implements a pivot arm with articulation capabilities that allow dynamic adjustment of the laser's position and angle. The pivot bearing device enables smooth rotation and positioning, making the adjustable system as easy to operate as a fixed one while achieving superior alignment precision through multiple degrees of freedom.
Solution Approach 2:
The locking device is designed to secure the pivot arm in the desired position after adjustment. This preliminary locking action maintains the aligned position during use, allowing the user to adjust once for precision and then easily lock it, combining adjustability with operational simplicity.
3Stability of the object's composition
If a locking device is added to fix the pivot arm position, then alignment stability improves, but the device complexity increases
Solution Approach 1:
The locking device is designed to be self-operating through a simple mechanism that the user can engage and disengage without additional tools or complex procedures. The locking device serves itself by maintaining the aligned position passively once locked, reducing the need for continuous active control and minimizing operational complexity.
4Measurement precision
If the laser can be rotated and positioned precisely, then alignment precision improves, but the ease of operation decreases
Solution Approach 1:
The pivot arm provides dynamic rotation capability with smooth movement characteristics. The articulation allows the laser to be rotated and positioned in multiple directions with ease, making the precise positioning as intuitive as natural hand movements while achieving high alignment precision through the extended range of motion.
