Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If exposed bus bar design is used, then electrical connection is achieved, but maintenance safety deteriorates due to risk of accidental contact

Engineering Contradiction:
Improvemaintenance safetyVSAvoidrisk of accidental contact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The bus bar is nested within a cavity formed by the first and second panels, with the second panel's lower surface extending over the cavity to enclose the bus bar. This nesting structure provides physical protection while maintaining electrical connection functionality, directly addressing the safety hazard of exposed bus bars.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The cavity structure acts as an intermediary barrier between the bus bar and external environment, preventing direct contact while allowing electrical connections to be made through designated access points. This mediator structure resolves the contradiction by providing both protection and functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If exposed bus bar design is used, then electrical connection is achieved, but repair complexity increases due to need for specialized equipment and trained technicians

Engineering Contradiction:
Improvebattery replacement easeVSAvoidmaintenance equipment complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The battery system is segmented into modular units with individual battery modules that can be replaced independently. The backbone structure with standardized cavities and coupling elements enables modular replacement without requiring disassembly of the entire system or specialized laboratory equipment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design enables end-users to perform battery replacements themselves through simple coupling element mechanisms that require no specialized tools or technical expertise. The self-service capability is achieved through intuitive mechanical coupling and positioning features.

Inventive Principle:
Principle #25Self-service

3Productivity

If traditional battery system design is used, then electrical functionality is maintained, but downtime increases during repairs

Engineering Contradiction:
Improvesystem availabilityVSAvoidrepair downtime
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The backbone structure with pre-formed cavities and positioning features is prepared in advance to receive battery modules. Coupling elements are pre-configured to enable quick connection and disconnection, allowing rapid battery replacement without system disassembly or reconfiguration.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system employs dynamic coupling elements that can be quickly connected and disconnected to facilitate rapid battery module replacement. The mechanical coupling design allows for fast attachment and detachment operations, minimizing system downtime during maintenance.

Inventive Principle:
Principle #15Dynamics

AI summary

An apparatus may include a first panel including a first upper surface and a first lower surface. The first upper surface may include a cavity extending into the first upper surface towards the first lower surface and a bus bar within the cavity. In addition, the apparatus may include a second panel having a second lower surface in direct contact with the first upper surface, wherein the second lower surface extends over a substantial portion of the cavity. In addition, the bus bar may include a first coupling element. The first coupling element may be configured to be mechanically coupled to a terminal of a battery module. Further, the cavity may position the first coupling element to align with the terminal.
