Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controllers with button battery compartments require time-consuming disassembly and often experience poor contact due to improper snap connections and wear, leading to unreliable battery replacement.
Innovation Solution
A remote controller back shell design featuring a snap-fit connection between the body and battery compartment, with a pinching part, male and female buckles, and a resilient block for easy battery replacement and secure positioning, ensuring quick and reliable battery access without disassembling the entire device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery compartment is fixed on the circuit board with a snap connection, then the battery compartment is securely positioned, but the button battery cannot be quickly replaced and requires disassembling the whole machine
Solution Approach 1:
The battery compartment is separated from the main body through a removable connection structure. The battery compartment includes a buckle that connects to a corresponding structure on the remote controller body, allowing the battery compartment to be independently removed without disassembling the entire device. This segmentation enables quick battery replacement while maintaining secure positioning during use.
2Ease of manufacture
If the snap connection between the battery compartment and circuit board is used, then the battery compartment is easily assembled, but the buckle may wear out and cause the button battery to shift
Solution Approach 1:
A resilient sheet is introduced between the button battery and the battery compartment to provide cushioning and compensation. This resilient sheet can deform to accommodate wear in the buckle connection, maintaining reliable electrical contact between the button battery and circuit board even as the mechanical connection experiences wear over time.
3Device complexity
If the button battery is held in place with a simple snap connection, then the structure is simple, but the button battery may shift during dropping or impact
Solution Approach 1:
The battery compartment includes a specifically designed buckle structure with corresponding engagement features. This localized structural enhancement provides strong mechanical retention and positioning for the button battery, preventing shifting during dropping or impact, while the overall structure remains relatively simple and easy to manufacture.
