Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for battery connection brackets require multiple components for different installation configurations, leading to inefficiencies and the need for various components to be stocked for specific mounting needs.
Innovation Solution
A multi-purpose fastening element with a flat connection body featuring multiple fastening holes and a fixing device with asymmetric recesses and locking pins, allowing for secure attachment to both walls and mounting rails without requiring specific positioning knowledge, enabling flexible and reversible attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components are used for wall mounting and mounting rail attachment, then secure fixation is achieved, but device complexity and inventory requirements increase
Solution Approach 1:
The connection body is designed with a universal fixing device that can attach to both walls and mounting rails. The fixing device includes a recess that accepts either a locking pin (for wall mounting) or engages with mounting rail holes, allowing one component to serve multiple mounting purposes without requiring separate wall plates or mounting-specific variants.
2Manufacturing precision
If multiple configuration-specific components are maintained, then precise positioning is achieved, but ease of operation and installation flexibility decrease
Solution Approach 1:
The connection body incorporates an asymmetric fixing device with a recess that can dynamically adapt to different mounting scenarios. The recess is positioned and shaped to work with either wall mounting (using locking pin through recess into wall) or mounting rail attachment (recess engaging with rail holes), allowing the same component to achieve precise positioning in both configurations without requiring the installer to select between different component variants.
3Adaptability or versatility
If a single multi-purpose component is used, then ease of operation and versatility improve, but achieving secure fixation and torsion-proof positioning becomes more difficult
Solution Approach 1:
The fixing device features an asymmetric recess with specific dimensional characteristics that enable secure fixation across different mounting types. The recess has a depth and cross-section designed to accommodate a locking pin for wall mounting while also engaging properly with mounting rail holes. The asymmetric positioning of the recess relative to the connection body's fastening holes ensures that when mounted on a rail, the geometry naturally prevents rotation and achieves torsion-proof positioning.
Solution Approach 2:
The locking pin serves as an intermediary element that mediates between the connection body and the mounting surface. Whether the mounting surface is a wall or a mounting rail, the locking pin passes through or engages with the recess to create a secure mechanical connection. This intermediary approach allows the same fixing mechanism to achieve reliable fixation in both wall mounting and rail mounting scenarios.
4Reliability
If additional wall plates and mounting-specific components are provided, then reliable attachment is achieved, but loss of time and inventory management complexity increase
Solution Approach 1:
The connection body is designed as a universal mounting component that eliminates the need for separate wall plates. The fixing device with its specifically positioned recess can directly attach to walls using a locking pin or to mounting rails by engaging with rail holes, providing reliable attachment in both scenarios with a single component type, thereby reducing installation time and simplifying inventory management.
