E-Bike Display Mount With Locking Slide for Reliable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display units for electric bicycles are ergonomically challenging to attach and detach, prone to misalignment, and can fail due to frequent use or low ambient temperatures, especially with elastically deformable mounting tabs.
Innovation Solution
A display unit with a retaining section that can be inserted into a mount and positively locked using a locking slide, allowing for intuitive and ergonomic attachment and detachment, featuring a hinge-like or parallel movement mechanism for secure integration into the handlebar stem.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If elastically deformable mounting tabs are used for attaching display elements, then the display elements can be flexibly mounted, but the mounting tabs can break due to frequent use or low ambient temperatures
Solution Approach 1:
The patent extracts the elastically deformable mounting tab from the system and replaces it with a rigid locking slide mechanism guided by guide rails. This removes the fragile component while maintaining the attachment function through a different mechanical principle (rigid guidance with lateral locking instead of elastic deformation).
Solution Approach 2:
The patent replaces the disposable mounting tab that can break with a more durable locking slide mechanism. The locking slide is designed to be replaceable if needed, but the overall system achieves significantly improved durability and reliability compared to the original mounting tab design.
2Ease of operation
If guide rail systems are used for mounting display elements, then the display elements can be easily inserted, but the components can become misaligned relative to the holder
Solution Approach 1:
The patent introduces guide rails as an intermediary element between the mounting bracket and the locking slide. The guide rails mediate the insertion process by providing precise lateral guidance, ensuring that the locking slide and display element become perfectly aligned with the holder during insertion, thereby eliminating misalignment issues.
Solution Approach 2:
The patent replaces the simple guide rail system with a more sophisticated mechanism combining guide rails and a locking slide. The guide rails provide precise mechanical guidance, while the locking slide engages with undercut features to lock the display element in place, achieving both ease of insertion and high alignment precision.
3Ease of operation
If frequent attachment and detachment operations are performed, then the display elements can be easily removed and attached, but the mounting tabs can break and cause holder failure
Solution Approach 1:
The patent introduces a dynamic locking mechanism where the locking slide can move laterally within the guide rails to engage and disengage from the undercut features. This dynamic system allows easy attachment and detachment through simple lateral motion of the locking slide, while the rigid guide rails and locking mechanism maintain holder reliability even with frequent operations.
Solution Approach 2:
The patent replaces the elastic mounting tab mechanism with a rigid locking slide and guide rail system. This mechanical substitution eliminates the fatigue and breaking issues associated with elastic deformation under frequent cycling, while maintaining ease of operation through the simple lateral locking and unlocking action.
4Reliability
If a locking mechanism with locking slides is used, then the display elements can be securely fixed, but the device complexity increases
Solution Approach 1:
The patent designs the locking slide to perform multiple functions: it provides lateral guidance within the guide rails, engages with the undercut to lock the display element, and can be easily actuated for release. The guide rails themselves serve dual purposes of guidance and structural support. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The locking slide is nested within the guide rail structure, with the locking mechanism integrated into the overall mounting assembly. The guide rails are integrated with the mounting bracket, creating a compact nested arrangement that minimizes the space and component count required for the locking mechanism.
