Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery holders are bulky, consume excessive space, and obscure battery polarity, making it difficult to determine and accommodate different polarities on printed circuit boards.
Innovation Solution
A compact battery holder design with a base and top that includes a window for viewing polarity and latches for easy access, featuring conductors with mounting surfaces that connect to the printed circuit board, minimizing height and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing battery holders completely enclose the battery, then the battery is protected and held securely, but the polarity of the battery cannot be viewed without opening or removing the battery holder
Solution Approach 1:
The battery holder is segmented into a base and a top portion that can be separated. The top includes a window that segments the viewing area, allowing polarity visibility while maintaining enclosure. This segmentation resolves the contradiction by providing both security (when closed) and visibility (through the window or when separated).
Solution Approach 2:
A window is introduced as an intermediary element in the top of the battery holder. This window allows light to pass through, enabling visibility of the battery polarity without requiring complete opening or removal of the holder. The window acts as a mediator that provides information while maintaining the protective enclosure.
2Reliability
If existing battery holders are designed to enclose the battery completely, then the battery is protected, but the height and area of the battery holder become large and bulky
Solution Approach 1:
The battery is nested within a compact holder structure where the top and base are designed to fit closely together. The conductors are integrated within the holder structure rather than extending externally, creating a nested arrangement that minimizes overall dimensions while maintaining protective enclosure.
Solution Approach 2:
The design optimizes the three-dimensional space by arranging components in different dimensions. The window in the top provides vertical access for visibility without increasing horizontal area. The conductors are positioned to minimize height while maintaining electrical connectivity, effectively utilizing spatial dimensions to reduce overall size.
3Ease of manufacture
If existing battery holders are designed without considering space minimization, then the structure is simple and robust, but the area and height consume excessive space on printed circuit boards
Solution Approach 1:
Multiple functions are merged into a single compact structure. The base and top form the protective enclosure while also housing the conductors and providing mounting surfaces. The window is integrated into the top structure, combining visibility function with the protective cover. This merging reduces overall area while maintaining structural simplicity and robustness.
Solution Approach 2:
The battery holder structure serves multiple functions simultaneously: protection (enclosure), visibility (window), electrical connection (conductors with mounting surfaces), and mounting (latches and connectors). This multi-functionality allows a single compact structure to replace what would otherwise require multiple separate components, minimizing area while maintaining ease of manufacture.

AI summary
A battery holder for attachment to a printed circuit board includes a base, a positive conductor, a negative conductor and a top. The base is to be fixed to the printed circuit board and the two conductors are fixed to the base. The top includes a window for viewing the polarity of the battery and is selectively attached to the base by a series of latches.
