Solution Overview

Problem

Existing console sliding armrest designs are prone to malfunction and reliability issues due to multiple components that are susceptible to environmental factors and misalignment, leading to sticking and slipping problems, which complicates the sliding operation and increases manufacturing costs.

Innovation Solution

A console sliding armrest assembly with a simplified guide assembly featuring a slider frame, guide plate, and a spring-biased rail system, where the rail is protected within a 'C' shaped channel to prevent environmental contamination, and a resilient arm with detents limits sliding movement, ensuring stable operation and reduced component count.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple biasing assemblies with multiple components are used to facilitate sliding movement, then the sliding operation can be controlled, but the device complexity increases and reliability decreases due to susceptibility to environmental contamination and component failure

Engineering Contradiction:
Improvesliding operation controlVSAvoidlong-term reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent combines multiple separate biasing assemblies into a single integrated biasing assembly. The first and second biasing members are merged into one component that provides both biasing forces, reducing the total number of parts from four (two rails, two biasing members) to three (two rails, one biasing assembly). This integration reduces complexity and improves reliability by eliminating potential failure points while maintaining the controlled sliding operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single biasing assembly performs multiple functions that were previously distributed across separate components. It provides biasing force for both the first and second rails, maintains contact between the rails and slide assembly, and compensates for environmental contamination effects. This multi-functional design simplifies the overall structure while ensuring reliable operation throughout the product lifecycle.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If multiple biasing assemblies with multiple components are used to facilitate sliding movement, then the sliding operation can be controlled, but the manufacturing cost increases due to the number of components required

Engineering Contradiction:
Improvesliding operation controlVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent merges multiple biasing components into a single integrated assembly, directly reducing the total part count. This consolidation reduces manufacturing costs by decreasing the number of components that need to be produced, inventoried, and assembled. The single biasing assembly can be manufactured as one unit or pre-assembled module, simplifying the supply chain and reducing assembly time and labor costs.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If a complex biasing assembly with multiple components is used, then the sliding movement can be facilitated, but the assembly is susceptible to environmental contamination and malfunction over time

Engineering Contradiction:
Improvesliding movement facilitationVSAvoidenvironmental contamination susceptibility
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

By integrating the biasing functions into a single assembly, the patent reduces the number of interfaces and joints where environmental contaminants can enter and cause malfunction. Fewer separate components mean fewer potential failure points and less surface area exposed to contaminants like dust, moisture, and debris, thereby improving resistance to environmental degradation while maintaining smooth sliding movement.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If multiple separate biasing assemblies are used, then the sliding operation can be controlled, but the device complexity increases prohibitive from cost and reliability standpoint

Engineering Contradiction:
Improvesliding operation controlVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent directly addresses device complexity by merging multiple separate biasing assemblies into one integrated unit. The single biasing assembly contains both biasing members and their mounting structures, reducing the component count from four separate parts to three integrated components. This simplification makes the overall device less complex while preserving the controlled sliding operation capability.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A console sliding armrest assembly for a vehicle includes a storage compartment having an opening for allowing ingress and egress of objects, and a console lid pivotally connected to the storage compartment. The lid may include a sliding armrest operatively engaged therewith. A guide assembly may be disposed within the lid for guiding the armrest, and may include a slider frame connected to the armrest. A guide plate may be connected to the lid for supporting the armrest, and a rail may be secured in the slider frame. The guide plate may be slidably engaged with the rail for allowing sliding movement of the armrest. A spring may be disposed between the slider frame and the rail, and may be engaged to either the slider frame or the rail for biasing the rail against the guide plate, and for thereby regulating tension in the guide assembly.
