Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs with LED gauges face challenges in accurately displaying battery discharge levels when removed from electronic devices due to light interference from neighboring LEDs, making it difficult to determine the on/off states and thus the discharge level.
Innovation Solution
Incorporating a partition wall system that guides light from LEDs to the display unit without affecting neighboring off-state LEDs, ensuring accurate on/off operation display and discharge level indication, even when the battery pack is not connected to a device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple LEDs are arranged closely to display battery discharge level, then the display can show more detailed battery status information, but light from neighboring LEDs interferes with each other causing inaccurate display
Solution Approach 1:
The patent divides the display area into separate segments using partition walls between adjacent LEDs. Each LED is isolated in its own light-emitting region, preventing light from neighboring LEDs from interfering with the display accuracy. This segmentation allows multiple LEDs to be arranged closely while maintaining individual light control and display precision.
Solution Approach 2:
Partition walls are introduced as intermediary structures between adjacent LEDs. These partition walls act as light barriers that guide and confine light from each LED to its corresponding display region, preventing light interference between neighboring LEDs while maintaining the compact arrangement of multiple LEDs.
2Area of stationary object
If LEDs are arranged in a compact display unit, then the battery gauge occupies less space, but light interference between neighboring LEDs makes it difficult to accurately determine battery state
Solution Approach 1:
The compact display unit is segmented into distinct light-emitting regions using partition walls. This segmentation allows LEDs to be arranged in a compact space while each LED's light is confined to its specific region, preventing interference and maintaining measurement precision despite the reduced overall area.
Solution Approach 2:
Each LED is provided with localized light guidance through partition walls that create distinct light-emitting regions. This local quality control ensures that light from each LED is directed only to its corresponding display area, maintaining accurate battery discharge level detection even in a compact arrangement where LEDs are closely spaced.

AI summary
A battery pack including a battery gauge. The battery gauge includes a circuit board, light emitting devices electrically connected to a battery cell on the circuit board and turned on or off according to a voltage of the battery cell, a display unit disposed outside a pack case at positions corresponding to the light emitting devices, and a partition wall guiding light of the light emitting device to a part of the display unit corresponding to the light emitting device. Since the partition wall prevents light of the light emitting device from affecting the neighboring light emitting device, an on/off operation of the light emitting device is accurately displayed on the display unit, so that a battery discharge level can be accurately detected.
