Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The durability of mechanisms for adjusting and securing the position of armrests in vehicle console boxes is not adequately improved, leading to potential instability and ergonomic issues during vehicle operation.
Innovation Solution
A console box assembly featuring a slide lock mechanism with a rod and bush system, where a biasing element and actuator work together to selectively engage and disengage the armrest, combined with a scissor linkage mechanism for height adjustment, enhancing the armrest's adjustability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple sliding mechanism is used for the arm rest, then the device complexity is reduced, but the durability and reliability of the adjustment mechanism deteriorates
Solution Approach 1:
A rod is introduced as an intermediary component between the arm rest and carrier. The rod transmits the sliding motion while being selectively engageable by the slide lock mechanism, distributing mechanical stresses and improving durability without significantly increasing overall complexity
Solution Approach 2:
The adjustment mechanism is segmented into distinct functional components: the sliding arm rest, the rod for motion transmission, and the slide lock mechanism with bush and actuator. This segmentation allows each component to be optimized for its specific function, improving overall reliability
2Reliability
If a robust slide lock mechanism is implemented, then the reliability of arm rest positioning is improved, but the device complexity increases
Solution Approach 1:
The slide lock mechanism incorporates a biasing element that automatically urges the bush into engagement with the rod, maintaining secure positioning without requiring continuous external force or complex control systems. The mechanism essentially locks itself into position
Solution Approach 2:
The slide lock mechanism transitions between engaged and disengaged states dynamically in response to actuator movement. The biasing element provides continuous force to maintain engagement, creating a reliable binary state system for positioning

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides improved durability and ergonomic adjustability of the armrest, ensuring secure positioning and comfortable operation while reducing wear and tear, thus enhancing the overall usability and longevity of the console box.
Implementation Method 1
a biasing element configured to bias the second bush into the first position
Implementation Method 2
a first bush disposed about the rod, the first bush comprising an internal surface configurable to contact the rod

AI summary
A console box assembly is provided. The console box assembly comprises a carrier and an armrest configured to slide relative to a carrier. The console box assembly further comprises: a rod coupled to one of the carrier and the armrest, wherein the rod is elongate in a direction in which the armrest is configured to slide relative to the carrier; and a slide lock mechanism coupled to the other of the carrier and the armrest, wherein the slide lock mechanism is configured to selectively engage the rod in order to restrict sliding of the armrest relative to the carrier, wherein the slide lock structure comprises: a first bush disposed about the rod, the first bush comprising an internal surface configurable to contact the rod, and a slope surface on opposite side of the first bush from the internal surface, a second bush configurable to engage the first bush at the slope surface in order to urge the internal surface of the first bush against the rod, an actuator to drive the second bush between a first position, in which the second bush engages the first bush and urges the internal surface of the first bush against the rod, and a second position, in which the second bush is disengaged from the first bush; and a biasing element configured to bias the second bush into the first position.
