Detachable DC Battery Pack Rails for Mis-Mounting Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical-device systems face issues with stress concentration and breakage at connection locations between support walls and the reference surface in battery-pack-type devices, leading to potential breakage during mounting and usage.
Innovation Solution
Incorporating battery-side distinguishing members on the battery-pack-type devices to differentiate compatible electrical devices and reinforce connection points, preventing incorrect mounting and enhancing the structural integrity by connecting the distinguishing members to both support walls and the reference surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery-side distinguishing members are added to differentiate compatible electrical devices, then device compatibility and prevention of mistaken mounting are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The battery-side distinguishing members are designed with asymmetric shapes that correspond to complementary asymmetric receiving structures on the electrical device. This asymmetry ensures that only compatible devices can be mounted correctly, preventing mistaken mounting while maintaining a relatively simple overall structure.
Solution Approach 2:
The battery-side distinguishing members serve dual functions: they act as compatibility indicators to prevent mistaken mounting, and simultaneously serve as reinforcing structures to reduce stress concentration at connection points. This multi-functionality improves reliability without proportionally increasing complexity.
2Strength
If battery-side distinguishing members are connected to both support walls and reference surface to reinforce connection points, then strength and resistance to breakage are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The battery-side distinguishing members are integrated into the battery pack housing as a unified structure rather than being separate components. This merging of functions (distinguishing + reinforcing) into a single structural element simplifies manufacturing compared to adding separate reinforcing plates or brackets.
Solution Approach 2:
The distinguishing members perform multiple functions simultaneously: providing mechanical reinforcement at connection points and enabling compatibility identification. This multi-functionality reduces the need for additional separate components, thereby easing manufacturing despite the enhanced strength requirements.
3Reliability
If battery-side distinguishing members are provided to ensure correct device compatibility, then reliability and device matching are improved, but ease of operation and mounting simplicity decrease
Solution Approach 1:
The asymmetric design of the distinguishing members and their receiving structures provides intuitive tactile feedback during mounting. Users can immediately sense whether the battery is oriented correctly without needing to interpret labels or indicators, maintaining ease of operation while ensuring compatibility.
Solution Approach 2:
The distinguishing members enable the system to self-verify compatibility through the mechanical interface itself. The presence or absence of the distinguishing member in its receiving structure automatically indicates compatibility, eliminating the need for separate identification steps or user judgment.

AI summary
A detachable DC power source includes: a reference surface extending in front-rear and left-right directions; support walls protruding upward from opposite ends of the reference surface and extending in the front-rear direction; battery-side rails protruding outward in the left-right direction from the upper ends of the pair of support walls and extending in the front-rear direction; and a first battery-side distinguishing region disposed between the support walls in the left-right direction and at a connection location between the reference surface and one of the support walls. A first battery-side distinguishing member is provided in the first battery-side distinguishing region and is directly connected to the one the support walls and to the reference surface. The detachable DC power source may be used to power an electrical device having a first device distinguishing part capable of receiving the first battery distinguishing member.
