Game Controller Internal Frame Recess Battery Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game controllers face challenges in making their internal structural bodies more compact due to the need for separate battery compartments and the risk of battery swelling contacting flexible substrates.
Innovation Solution
A game controller design featuring an internal frame with a recess for the battery and a flexible substrate that covers part of the battery's surface, creating a gap to prevent contact and allowing for a compact layout, with a retaining member to prevent battery ejection and a flexible substrate that can deform to accommodate swelling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a separate battery compartment is provided in the internal structural body, then the battery can be accommodated, but the internal structural body becomes larger and less compact
Solution Approach 1:
The patent merges the battery accommodation function with the internal frame structure by forming a recess directly in the internal frame. This eliminates the need for a separate battery compartment, thereby reducing the overall volume of the internal structural body while maintaining the battery's secure placement.
Solution Approach 2:
The internal frame is designed to serve multiple functions: it provides structural support, houses the flexible substrate, and simultaneously accommodates the battery through its recess. This multi-functionality reduces the need for additional dedicated components, making the internal structural body more compact.
2Reliability
If the flexible substrate covers the entire second surface of the battery, then complete coverage is achieved, but the risk of contact with swollen battery increases
Solution Approach 1:
The flexible substrate is designed to cover only specific portions of the battery's second surface rather than the entire surface. This localized coverage strategy reduces the area where contact with a swollen battery could occur, thereby improving reliability while minimizing harmful contact effects.
Solution Approach 2:
The patent introduces a gap between the flexible substrate and the battery surface, which acts as an intermediary space. This gap prevents direct contact between the substrate and the battery, even when the battery swells, thereby reducing the risk of harmful contact while maintaining necessary electrical connections through conductive patterns.
3Reliability
If the first height is made greater than the second height, then a gap is formed to prevent contact, but the internal structural body volume increases
Solution Approach 1:
The patent creates a gap between the flexible substrate and the battery by making the first height slightly greater than the second height. This partial separation is sufficient to prevent contact with swollen batteries while minimizing the increase in internal structural body volume, as the gap is kept to the minimum necessary dimension.

AI summary
A game controller according to the present disclosure includes: a housing; and an internal structural body accommodated inside of the housing. The internal structural body includes at least: an internal frame having an installation surface and a recess adjacent to the installation surface; a battery that is accommodated in the recess of the internal frame and has a first surface that opposes a bottom surface of the recess and a second surface on a side opposite to that of the first surface; and a flexible substrate that is installed on the installation surface of the internal frame and includes a conductive pattern. The flexible substrate is arranged so as to cover at least a portion of the second surface of the battery accommodated in the recess.
