Digital X-ray Detector Removable Battery Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable digital X-ray detectors face limitations due to tethered power and communication constraints, which can interfere with positioning and operation, and wireless detectors experience slower data transfer rates and battery downtime with periodic recharging, leading to heat generation and reduced battery longevity.
Innovation Solution
A digital detector with a user-accessible connector that can receive either a removable battery or a tether for power, allowing wireless communication and data storage in an internal memory device, enabling flexible operation modes and minimizing downtime by allowing battery replacement and recharging without interrupting data acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a tether is used to provide power and communication, then data transfer rate is improved, but positioning flexibility deteriorates
Solution Approach 1:
The connector is designed to dynamically switch between two operational states: tethered mode (cable connected) for high-speed data transfer and wireless mode (battery powered) for flexible positioning. This dynamic configuration allows the system to adapt to different operational requirements, resolving the contradiction between data transfer rate and positioning flexibility.
2Ease of operation
If an internal battery is used for wireless operation, then positioning flexibility is improved, but downtime increases due to periodic recharging
Solution Approach 1:
The power system is segmented into a removable battery component and a fixed detector body. This segmentation allows the battery to be independently replaced when depleted, eliminating the need to recharge the entire detector unit. The detector can remain in use with a fresh battery while the old battery is recharged separately, thus minimizing downtime and maintaining positioning flexibility.
3Ease of operation
If an internal battery is frequently recharged, then wireless operation is maintained, but heat generation increases and battery longevity decreases
Solution Approach 1:
The battery is extracted as a separate, removable component from the detector system. This extraction allows the battery to be replaced rather than repeatedly recharged, eliminating the cyclic thermal stress that occurs during frequent charging cycles. The detector can maintain continuous wireless operation by swapping in pre-charged batteries, thereby reducing heat generation and extending battery longevity while preserving wireless operational capability.
4Duration of action of stationary object
If a removable battery is used, then battery longevity is improved by reducing recharging cycles, but device complexity increases
Solution Approach 1:
The connector is designed with universal functionality to accommodate both tethered power/communication and removable battery configurations. This multi-functionality is achieved through a standardized interface that can receive either a tether or a battery pack, allowing the system to operate in wireless mode with extended battery longevity while maintaining the option for tethered operation. The added complexity is minimal and justified by the significant improvement in battery lifespan and operational flexibility.
