Solution Overview

Problem

Existing working vehicles require large holes for cable movement, leading to dust ingress and aesthetic deterioration.

Innovation Solution

A flexible longitudinal member coupled to a movable member, guided by a movable member with a guide mechanism, and a fixing member with a cutout portion, to prevent excessive deformation and dust ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a large long hole is formed in the plate to allow cable movement, then the cable can move with the seat, but dust flows into the cabin and aesthetic appearance deteriorates

Engineering Contradiction:

Improvecable movement capabilityVSAvoiddust ingress

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies the dynamics principle by making the plate itself movable rather than fixed. The plate is configured to move together with the seat, allowing the cable to move smoothly through the hole without requiring a large opening. This dynamic configuration maintains a smaller hole size while still accommodating cable movement, thereby preventing dust ingress and preserving aesthetic appearance.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The plate serves multiple functions: it guides the cable, moves with the seat to accommodate cable displacement, and maintains a relatively small opening to prevent dust ingress. By integrating these functions into a single movable plate component, the design avoids the need for separate large openings or additional sealing mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a large long hole is formed in the plate to allow cable movement, then the cable can move with the seat, but aesthetic appearance deteriorates

Engineering Contradiction:

Improvecable movement capabilityVSAvoidaesthetic appearance

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The plate is designed to move dynamically with the seat, which allows the cable to pass through a smaller hole while still accommodating the full range of motion. This reduces the visual impact of the hole and maintains better aesthetic appearance compared to a large static opening.

Inventive Principle:

Principle #15Dynamics

3Object-affected harmful factors

If a large-sized seal member is used to close the long hole, then dust ingress is prevented, but device complexity increases

Engineering Contradiction:

Improvedust ingress preventionVSAvoidseal member requirement

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

By making the plate movable, the system prevents dust ingress through a smaller opening without requiring additional seal members. The dynamic movement of the plate itself accommodates cable displacement, eliminating the need for separate sealing components and reducing overall device complexity.

Inventive Principle:

Principle #15Dynamics

AI summary

Provided is a working vehicle capable of suitably guiding a longitudinal member. A movable loader lever, cables and that are formed in a flexible longitudinal shape, are coupled to the loader lever, and move with movement of the loader lever, and a movable member that includes an insertion hole through which the cables and are inserted and that is provided to be relatively movable with respect to a vehicle body are included, a plate-shaped member that is fixed to the vehicle body and includes a cutout portion is further included, and the movable member is provided to be relatively movable with respect to the plate-shaped member such that the insertion hole moves within a range inside the cutout portion.
