Modular Laptop Chassis for Battery and Connector Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems require users to separate the base chassis top cover from the bottom cover to replace batteries, power connectors, or IO connectors, which can damage internal components and necessitate replacing the motherboard.
Innovation Solution
A modular design allowing users to lift a removable palm rest and touchpad assembly to access batteries and replace IO and power connectors without separating the base chassis covers, using a replaceable IO and power pin/port connector module that mates with the motherboard without replacing it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users separate the base chassis top cover from the bottom cover to replace batteries and connectors, then access to internal components is improved, but the risk of damaging internal components and chassis increases
Solution Approach 1:
The base chassis is segmented into modular components: a removable palm rest and touchpad assembly, a separate IO and power pin/port connector module, and the main base chassis housing the motherboard. This segmentation allows users to remove and replace specific components (batteries, connectors) without separating the top cover from the bottom cover, thus maintaining chassis integrity while providing access to internal components.
2Ease of repair
If users separate the base chassis covers to replace connectors, then connector replacement is enabled, but the motherboard must also be replaced increasing complexity
Solution Approach 1:
The IO and power pin/port connector module is designed as a separate, removable module that interfaces with the motherboard through a connector. This allows the connector module to be replaced independently without affecting the motherboard, significantly simplifying repair procedures and reducing device complexity.
Solution Approach 2:
The IO and power connectors are extracted from the motherboard assembly and placed in a separate removable module. This extraction enables users to replace only the connector module when connectors fail, rather than replacing the entire motherboard, thus reducing repair complexity and cost.
3Ease of operation
If a modular design with removable palm rest and touchpad assembly is implemented, then battery and connector replacement becomes easier, but device structure becomes more complex
Solution Approach 1:
The palm rest and touchpad assembly is designed as a removable module that can be easily detached from the base chassis. This segmentation provides users with direct access to batteries and connectors for replacement, while the modular design uses standardized connectors and mounting mechanisms that simplify the overall assembly process during manufacturing.

AI summary
A base chassis assembly for an information handling system for replacement of power and input/output (IO) connectors or a battery may comprise a base chassis top cover joined to a base chassis bottom cover and including a replaceable IO and power pin/port connector module and a removable palm rest and touchpad assembly enclosing a battery disposed within base chassis assembly. A connector module circuit board operably connected to power and IO connectors in the replaceable IO and power pin/port connector module slidable to slide the power and IO connectors into sidewall apertures of the base assembly upon installation of the replaceable IO and power pin/port connector module in the base chassis assembly and the removable palm rest and touchpad assembly removable with removal of at least one fastener to access and service the battery providing for simple servicing or replacement of parts for the information handling system.
