Solution Overview

Problem

The bulky electrochemical battery in electric or hybrid motor vehicles occupies a large volume, limiting the space for connection means between vehicle systems and exposing them to damage, reducing passenger compartment volume and increasing the risk of shock or damage.

Innovation Solution

An energy storage device with a profiled and hollow stretcher supporting the battery, where connecting means such as hydraulic lines, electrical cables, or mechanical rods extend through the device, utilizing the available volume inside the battery to house these connections, providing protection and maintaining the device's compact size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the battery contains a large number of electrochemical modules to ensure maximum autonomy, then the energy storage capacity is improved, but the volume occupied by the battery increases

Engineering Contradiction:
Improveenergy storage capacityVSAvoidbattery volume
Core Design Contradiction:
Use of energy by moving objectVSVolume of stationary object

Solution Approach 1:

The patent applies nesting by placing connecting means (hydraulic lines, electrical cables, mechanical rods) inside the hollow interior chambers of the battery's structural elements (stretchers and housing). This allows the connecting means to be nested within the battery's existing structure, utilizing otherwise wasted space and eliminating the need for separate routing paths outside the battery.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent transitions from two-dimensional surface routing of connecting means to three-dimensional internal routing by creating hollow profiled elements with interior chambers. This dimensional change allows connecting means to pass through the volume of the battery structure rather than along its external surfaces, effectively using the third dimension (depth/volume) to resolve space constraints.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If connection means extend above the battery between the upper face of the battery and the passenger compartment floor, then the connecting means can be routed, but the volume available to passengers is reduced and the connecting means are exposed to damage

Engineering Contradiction:
Improveconnecting means routingVSAvoidrisk of impact or damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The connecting means are nested within the hollow interior chambers of the battery structure, protecting them from external damage while routing them through the battery's own structural elements. This eliminates their exposure to the passenger compartment environment and potential impact hazards.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The hollow profiled structural elements of the battery act as intermediary protective channels, mediating between the need to route connecting means and the need to protect them from damage. These structural elements serve as both load-bearing components and protective conduits for the connecting means.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If connection means extend above the battery, then the connecting means can be connected, but the volume available for passengers is severely limited

Engineering Contradiction:
Improveconnecting means connectionVSAvoidpassenger compartment volume
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The connecting means are nested within the battery's hollow structural elements, removing them from the passenger compartment space entirely. This nesting approach allows the connecting means to be routed through the battery's interior chambers without encroaching on passenger volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent moves the routing of connecting means from the vertical space above the battery (which would reduce passenger volume) to the horizontal/three-dimensional space within the battery structure itself, effectively using the battery's internal volume rather than external space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
