Bicycle Battery Holder Locking Rail for Tool-Free Secure Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle battery holding devices lack user-friendliness and versatility in accommodating batteries of different lengths, and often require tools for assembly and disassembly, posing challenges in secure and tool-free fixation.
Innovation Solution
A holding device with a locking unit featuring a first and second locking element, an actuation unit, and a carrier unit that allows for one-sided axial fixation and easy electrical contacting, enabling tool-free operation and secure attachment of batteries of varying lengths without damaging them, using a combination of fastening elements and a guide rail for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing holding devices are used, then battery fixation is achieved, but tool-free operation and user-friendliness are compromised
Solution Approach 1:
The locking unit is designed to be actuated directly by the user without requiring external tools. The actuating unit engages with the locking element to release the battery, creating a self-service system where the user performs the entire locking and unlocking operation using only their hand, thus achieving both ease of operation and reliable fixation.
Solution Approach 2:
The holding device is divided into distinct functional components: the locking unit with locking elements for secure fixation, and the actuating unit for tool-free release. This segmentation allows each component to specialize in its function - the locking elements provide reliable mechanical engagement while the actuating unit provides user-friendly operation without tools.
2Adaptability or versatility
If holding devices accommodate batteries of different lengths, then versatility is improved, but device complexity increases
Solution Approach 1:
The carrier unit is designed with a universal receptacle structure that can accommodate batteries of varying lengths through a single standardized interface. The locking unit engages with the battery at a specific location regardless of total battery length, allowing the same holding device structure to universally secure different battery sizes without requiring multiple specialized components.
Solution Approach 2:
The locking mechanism focuses its securing action at a specific local region of the battery (where the locking elements engage), rather than requiring complex structures along the entire length. This localized engagement approach allows versatile accommodation of different battery lengths while maintaining simple overall device structure.
3Reliability
If fastening elements are used for secure attachment, then reliability is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The locking elements are designed to dynamically transition between locked and unlocked states. During assembly, the locking elements automatically engage with the battery to provide secure attachment. During disassembly, the actuating unit triggers a dynamic release mechanism that allows quick and tool-free unlocking, thus achieving both secure attachment and ease of operation.
Solution Approach 2:
The traditional mechanical fastening system requiring screws or clips is replaced with a spring-loaded locking element system. The spring provides continuous securing force for reliable attachment, while the actuating unit mechanically triggers the release, substituting complex manual fastening operations with a simple push-button or lever action that maintains security while enabling easy assembly and disassembly.
