Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing working vehicles face reduced workability due to sensor brackets obstructing maintenance tasks, particularly when fixed to the left and right side surfaces of a weight bracket, hindering access to the bonnet and other components.

Innovation Solution

A working vehicle design featuring a weight support portion with a support member that integrates a hollow structure, allowing for the accommodation of components and facilitating maintenance, while supporting a front detection section with adjustable angle and a hollow shape to minimize interference with headlights and hitch pins.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sensor brackets are fixed to the left and right side surfaces of the weight bracket, then the detection device can be properly positioned, but the brackets obstruct worker access to the bonnet and reduce workability

Engineering Contradiction:

Improvedetection device positioningVSAvoidworker access to bonnet

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent transitions from lateral mounting (left-right sides) to vertical mounting (upper surface) of the weight bracket. This dimensional change in attachment location eliminates the obstruction problem while preserving detection functionality, as the sensor brackets are now positioned above the bonnet area rather than beside it.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Strength

If solid support member is used, then structural strength is sufficient, but maintenance access and component accommodation are limited

Engineering Contradiction:

Improvesupport member strengthVSAvoidmaintenance access

Core Design Contradiction:

StrengthVSEase of repair

Solution Approach 1:

The support member is designed with a hollow internal structure that can accommodate cables, connectors, and other components. This nesting approach allows maintenance components to be integrated within the support member itself, improving access and organization while preserving external structural strength.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The support member is divided into external structural walls and internal hollow space. This segmentation allows the outer shell to provide strength while the inner cavity provides maintenance access and component accommodation, resolving the contradiction between structural integrity and serviceability.

Inventive Principle:

Principle #1Segmentation

3Ease of manufacture

If support member has constant lateral width, then manufacturing is simple, but it blocks light from headlights and reduces aerodynamic efficiency

Engineering Contradiction:

Improvesupport member fabricationVSAvoidheadlight light blockage

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The support member features variable cross-sectional dimensions along its length, with the lateral width being larger at the base for structural support and progressively narrower toward the top to reduce light blockage. This local variation in geometry optimizes both structural performance and optical clearance while remaining manufacturable.

Inventive Principle:

Principle #3Local quality
